:
1 Save me, O God, by thy name, and judge me by thy strength. 2 Hear my prayer, O God; give ear to the words of my mouth. 3 For strangers are risen up against me, and oppressors seek after my soul: they have not set God before them. Selah. 4 Behold, God is mine helper: the Lord is with them that uphold my soul. 5 He shall reward evil unto mine enemies: cut them off in thy truth. 6 I will freely sacrifice unto thee: I will praise thy name, O LORD; for it is good. 7 For he hath delivered me out of all trouble: and mine eye hath seen his desire upon mine enemies.
[AD 367] Hilary of Poitiers on Psalms 54:1-2
The suffering of the prophet David is … a type of the passion of our God and Lord Jesus Christ. This is why David’s prayer also corresponds in sense with the prayer of Christ, who being the Word, was made flesh. As man, Christ suffered all things in a human fashion and spoke in a human fashion in everything he said. He, who bore human infirmities and took on himself the sins of people, approached God in prayer with the humility proper to human beings. This interpretation, even though we are unwilling and slow to receive it, is required by the meaning and force of the words, so that there can be no doubt that everything in the psalm is uttered by David as Christ’s mouthpiece. For he says, “Save me, O God, by your name.” Thus he prays in bodily humiliation, using the words of his own prophet, the only-begotten Son of God, who at the same time was claiming again the glory that he had possessed from eternity. David asks to be saved by the name of God whereby he was called and wherein he was begotten, in order that the name of God, which rightly belonged to his former nature and kind, might be able to save him in that body wherein he had been born.

[AD 367] Hilary of Poitiers on Psalms 54:1-2
“Hear my prayer, O God, give ear to the words of my mouth.” The obvious thing for the prophet to say was, “O God, hear me.” But because he is speaking as the mouthpiece of him who alone knew how to pray, we are constantly and repeatedly assured that God will hear our prayer. The words of Paul teach us that no one knows how he ought to pray: “For we know not how to pray as we ought.” A human being in his weakness, therefore, has no right to demand that his prayer should be heard; for even the teacher of the Gentiles does not know the true purpose and intention of prayer, even after the Lord had provided a model. What we are shown here is the perfect confidence of Jesus, who alone sees the Father, who alone knows the Father, who alone can pray all night long—the Gospel tells us that the Lord continued all night in prayer7—who in the mirror of words has shown us the true image of the deepest of all mysteries in the simple words we use in prayer. And so, in demanding that his prayer be heard and in order to teach us that this was the prerogative of his perfect confidence, David added, “Give ear to the words of my mouth.” Now can any person have such confidence that he can desire that the words of his mouth should be heard? It is with words, for instance, that we express emotions and mental instincts, when inflamed by anger, moved by hatred to slander, by flattery to fawn, motivated by hope of gain or fear of shame to lie or by resentment at injury to insult someone? Was there ever a person who was pure and patient throughout his life who was not subject to these human shortcomings? The only person who could have confidently desired this is one who has not sinned, in whose mouth there has been no deceit, who gave his back to the smiters, who did not turn his cheek away from the blow, who did not avoid scorn and spitting, who never resisted the will of him who ordered it all but was always gladly obedient.

[AD 367] Hilary of Poitiers on Psalms 54:1
The doctrines of the Gospel were well known to holy and blessed David in his capacity of Prophet, and although it was under the Law that he lived his bodily life, he yet filled, as far as in him lay, the requirements of the Apostolic behest and justified the witness borne to him by God in the words: I have found a man after My own heart, David, the son of Jesse. He did not avenge himself upon his foes by war, he did not oppose force of arms to those that laid wait for him, but after the pattern of the Lord, Whose name and Whose meekness alike he foreshadowed, when he was betrayed he entreated, when he was in danger he sang psalms, when he incurred hatred he rejoiced; and for this cause he was found a man after God's own heart. For although twelve legions of angels might have come to the help of the Lord in His hour of passion, yet that He might perfectly fulfil His service of humble obedience, He surrendered Himself to suffering and weakness, only praying with the words: Father into Your hands I commend My spirit. Luke 23:46 After the same pattern, David, whose actual sufferings prophetically foretold the future sufferings of the Lord, opposed not his enemies either by word or act; in obedience to the command of the Gospel, he would not render evil for evil, in imitation of his Master's meekness, in his affliction, in his betrayal, in his fight, he called upon the Lord and was content to use His weapons only in his contest with the ungodly.

Now to this Psalm is prefixed a title arising out of an historical event; but before the event is described we are instructed as to the scope, time and application of the incidents underlying it. First we have: For the end of the meaning of that David. Then there follows: When the Ziphims came and said to Saul: behold, is not David hid with us? Thus David's betrayal by the Ziphims awaits for its interpretation the end. This shows that what was actually being done to David contained a type of something yet to come; an innocent man is harassed by railing, a prophet is mocked by reviling words, one approved by God is demanded for execution, a king is betrayed to his foe. So the Lord was betrayed to Herod and Pilate by those very men in whose hands He ought to have been safe. The Psalm then awaits the end for its interpretation, and finds its meaning in the true David, in Whom is the end of the Law, that David who holds the keys and opens with them the gate of knowledge, in fulfilling the things foretold of Him by David.

The meaning of the proper name, according to the exact sense of the Hebrew, affords us no small assistance in interpreting the passage. Ziphims mean what we call sprinklings of the face; these were called in Hebrew Ziphims. Now, by the Law, sprinkling was a cleansing from sins; it purified the people through faith by the sprinkling of blood, of which this same blessed David thus speaks: You shall sprinkle me with hyssop and I shall be cleansed ; the Law, through faith, providing as a temporary substitute, in the blood of whole burnt-offerings, a type of the sprinkling with the blood of the Lord, which was to be. But this people, like the people of the Ziphims, being sprinkled on their face and not in their faith, and receiving the cleansing drops on their lips and not in their hearts, turned faithless and traitors towards their David, as God had foretold by the Prophet: This people honours Me with their lips, but their heart is far from Me. They were ready to betray David because, the faith of their heart being dead, they had performed all the mystical ceremonies of the Law with deceitful face.

The suffering of the Prophet David is, according to the account we have given of the title, a type of the Passion of our God and Lord Jesus Christ. This is why his prayer also corresponds in sense with the prayer of Him Who being the Word was made flesh: in such wise that He Who suffered all things after the manner of man, in everything He said, spoke after the manner of man; and He who bore the infirmities and took on Him the sins of men approached God in prayer with the humility proper to men. This interpretation, even though we be unwilling and slow to receive it, is required by the meaning and force of the words, so that there can be no doubt that everything in the Psalm is uttered by David as His mouthpiece. For he says: Save me O God, by Your name. Thus prays in bodily humiliation, using the words of His own Prophet, the Only-begotten Son of God, Who at the same time was claiming again the glory which He had possessed before the ages. He asks to be saved by the Name of God whereby He was called and wherein He was begotten, in order that the Name of God which rightly belonged to His former nature and kind might avail to save Him in that body wherein He had been born.

And because the whole of this passage is the utterance of One in the form of a servant— of a servant obedient unto the death of the Cross— which He took upon Him and for which He supplicates the saving help of the Name that belongs to God, and being sure of salvation by that Name, He immediately adds: and judge Me by Your power. For now as the reward for His humility in emptying Himself and assuming the form of a servant, in the same humility in which He had assumed it, He was asking to resume the form which He shared with God, having saved to bear the Name of God that humanity in which as God He had obediently condescended to be born. And in order to teach us that the dignity of this Name whereby He prayed to be saved is something more than an empty title, He prays to be judged by the power of God. For a right award is the essential result of judgment, as the Scripture says: Becoming obedient unto death , yea, the death of the Cross. Wherefore also God highly exalted Him and gave unto Him the name which is above every name. Thus, first of all the name which is above every name is given unto Him; then next, this is a judgment of decisive force, because by the power of God, He, Who after being God had died as man, rose again from death as man to be God, as the Apostle says: He was crucified from weakness, yet He lives by the power of God 2 Corinthians 13:4 , and again: For I am not ashamed of the Gospel: for it is the power of God unto salvation to every one that believes. Romans 1:16 For by the power of the Judgment human weakness is rescued to bear God's name and nature; and thus as the reward for His obedience He is exalted by the power of this judgment unto the saving protection of God's name; whence He possesses both the Name and the Power of God. Again, if the Prophet had begun this utterance in the way men generally speak, he would have asked to be judged by mercy or kindness, not by power. But judgment by power was a necessity in the case of One Who being the Son of God was born of a virgin to be Son of Man, and Who now being Son of Man was to have the Name and power of the Son of God restored to Him by the power of judgment.
[AD 430] Augustine of Hippo on Psalms 54:1-2
There are two ways to interpret the affirmation that he “shall judge the living and the dead.” On the one hand, we may understand by “the living” those who are not yet dead but who will be found living in the flesh when he comes; and we may understand by “the dead” those who have left the body or who shall have left it before his coming. Or, on the other hand, “the living” may signify “the righteous,” and “the dead” may signify “the unrighteous”—since the righteous are to be judged as well as the unrighteous. For sometimes the judgment of God is passed on the evil people, as in the word, “But they who have done evil [shall come forth] to the resurrection of judgment.” And sometimes it is passed on the good, as in the word, “Save me, O God, by your name, and judge me in your strength.” Indeed, it is by the judgment of God that the distinction between good and evil is made, to the end that, being freed from evil and not destroyed with the evildoers, the good may be set apart at his right hand. This is why the psalmist cried, “Judge me, O God,” and, as if to explain what he had said, “and defend my cause against an unholy nation.”

[AD 430] Augustine of Hippo on Psalms 54:1
"O God, in Your name make me safe, and in Your virtue judge me" [Psalm 54:1]. Let the Church say this, hiding amid the Ziphites. Let the Christian body say this, keeping secret the good of its morals, expecting in secret the reward of its merits, let it say this: "In Your virtue judge me." You have come, O Christ, humble You have appeared, despised You have been, scourged hast been, crucified hast been, slain hast been; but, on the third day hast risen, on the fortieth day into Heaven hast ascended: You sit at the right hand of the Father, and no one sees: Your Spirit thence You have sent, which men that were worthy have received; fulfilled with Your love, the praise of that very humility of Yours throughout the world and nations they have preached: Your name I see to excel among mankind, but nevertheless as weak to us have You been preached. For not even did that Teacher of the Gentiles say, that among us he knew anything, "Save Christ Jesus, and Him crucified;" [1 Corinthians 2:2] in order that of Him we might choose the reproach, rather than the glory of the flourishing Ziphites. Nevertheless, of Him he says what? "Although He died of weakness, yet He lives of the power of God." He came then that He might die of weakness, He is to come that He may judge in the power of God: but through the weakness of the Cross His name has been illustrious. Whosoever shall not have believed upon the name made illustrious through weakness, shall stand in awe at the Judge, when He shall have come in power. But, lest He that once was weak, when He shall have come strong, with that fan send us to the left hand; may He "save us in His name, and judge us in His virtue." For who so rash as to have desired this, as to say to God, for instance "Judge me"? Is it not wont to be said to men for a curse, "God judge you"? So evidently it is a curse, if He judge you in His virtue; and shall not have saved you in His name: but when in name precedent He shall have saved you, to your health in virtue consequent He shall judge. Be thou without care: that judgment shall not to you be punishment, but dividing. For in a certain Psalm thus is said: "Judge me, O God, and divide my cause from the nation unholy."...

[AD 367] Hilary of Poitiers on Psalms 54:2
The obvious thing for the Prophet to say was, O God, hear me. But because he is speaking as the mouthpiece of Him, Who alone knew how to pray, we are given a constantly reiterated demand that prayer shall be heard. The words of St. Paul teach us that no man knows how he ought to pray: For we know not how to pray as we ought. Man in his weakness, therefore, has no right to demand that his prayer shall be heard: for even the teacher of the Gentiles does not know the true object and scope of prayer, and that, after the Lord had given a model. What we are shown here is the perfect confidence of Him, Who alone sees the Father, Who alone knows the Father, Who alone can pray the whole night through— the Gospel tells us that the Lord continued all night in prayer— Who in the mirror of words has shown us the true image of the deepest of all mysteries in the simple words we use in prayer. And so, in making the demand that His prayer should be heard, he added, in order to teach us that this was the prerogative of His perfect confidence: Give ear unto the words of My mouth. Now can any man suppose that it is a human confidence which can thus desire that the words of his mouth should be heard? Those words, for instance, in which we express the motions and instincts of the mind, either when anger inflames us, or hatred moves us to slander, or pain to complaint, when flattery makes us fawn, when hope of gain or shame of the truth begets the lie, or resentment over injury, the insult? Was there ever any man at all points so pure and patient in his life as not to be liable to these failings of human instability? He alone could confidently desire this Who did no sin, in Whose mouth was no deceit, Who gave His back to the smiters, Who turned not His cheek from the blow, Who did not resent scorn and spitting, Who never crossed the will of Him, to Whose Will ordering it all He gave in all points glad obedience.
[AD 430] Augustine of Hippo on Psalms 54:2
"O God, hearken to my prayer, in Your ears receive the words of my mouth" [Psalm 54:2]....To You may my prayer attain, driven forth and darted out from the desire of Your eternal blessings: to Your ears I send it forth, aid it that it may reach, lest it fall short in the middle of the way, and fainting as it were it fall down. But even if there result not to me now the good things which I ask, I am secured nevertheless that hereafter they will come. For even in the case of transgressions a certain man is said to have asked of God, and not to have been hearkened to for his good. For privations of this world had inspired him to prayer, and being set in temporal tribulations he had wished that temporal tribulations should pass away, and there should return the flower of grass; and he says, "My God, my God, why have You forsaken me?" The very voice of Christ it is, but for His members' sake. "The words," he says, "of my transgressions I have cried to You throughout the day, and You have not hearkened: and by night, and not for the sake of folly to me:" that is, "and by night I have cried, and You have not hearkened; and nevertheless in this very thing that You have not hearkened, it is not for the sake of folly to me that You have not hearkened, but rather for the sake of wisdom that You have not hearkened, that I might perceive what of You I ought to ask. For those things I was asking which to my cost perchance I should have received." Thou ask riches, O man; how many have been overset through their riches? Whence do you know whether to you riches may profit? Have not many poor men more safely been in obscurity; having become rich men, so soon as they have begun to blaze forth, they have been a prey to the stronger? How much better they would have lain concealed, how much better they would have been unknown, that have begun to be inquired after not for the sake of what they were, but for the sake of what they had! In these temporal things therefore, brethren, we admonish and exhort you in the Lord, that you ask not anything as if it were a thing settled, but that which God knows to be expedient for you. For what is expedient for you, you know not at all. Sometimes that which you think to be for you is against you, and that which you think to be against you is for you. For sick you are; do not dictate to the physician the medicines he may choose to set beside you. If the teacher of the Gentiles, Paul the Apostle, says, "For what we should pray for as we ought, we know not," [Romans 8:26] how much more we? Who nevertheless, when he seemed to himself to pray wisely, namely, that from him should be taken away the thorn of the flesh, the angel of Satan, that did buffet him, in order that he might not in the greatness of the revelations be lifted up, heard from the Lord what? Was that done which he wished? Nay, in order to that being done which was expedient, he heard from the Lord, I say, what? "Thrice," he says, "I besought the Lord that He would take it from me; and He said to me, My Grace suffices for you: for virtue in weakness is made perfect." [2 Corinthians 12:8-9] Salve to the wound I have applied; when I applied it I know, when it should be taken away I know. Let not a sick man draw back from the hands of the physician, let him not give advice to the physician. So it is with all these things temporal. There are tribulations; if well you worship God, you will know that He knows what is expedient for each man: there are prosperities; take the more heed, lest these same corrupt your soul, so that it withdraw from Him that has given these things....

[AD 367] Hilary of Poitiers on Psalms 54:3
He has next added the reason why He prays for His words to be heard: For strangers are risen up against Me and violent men have sought after My soul; they have not set God before their eyes. The Only-begotten Son of God, the Word of God and God the Word— although assuredly He could Himself do all things that the Father could, as He says: What things soever the Father does, the Son also does in like manner John 5:19, while the name describing the divine nature which was His inseparably involved the inseparable possession of divine power—yet in order that He might present to us a perfect example of human humility, both prayed for and underwent all things that are the lot of man. Sharing in our common weakness He prayed the Father to save Him, so that He might teach us that He was born man under all the conditions of man's infirmity. This is why He was hungry and thirsty, slept and was weary, shunned the assemblies of the ungodly, was sad and wept, suffered and died. And it was in order to make it clear that He was subject to all these conditions, not by His nature, but by assumption, that when He had undergone them all He rose again. Thus all His complaints in the Psalms spring from a mental state belonging to our nature. Nor must it cause surprise if we take the words of the Psalms in this sense, seeing that the Lord Himself testified, if we believe the Gospel, that the Psalms spiritually foretold His Passion.

Now they were strangers that rose up against Him. For these are no sons of Abraham, nor sons of God, but a brood of vipers, servants of sin, a Canaanitish seed, their father an Amorite and their mother a daughter of Heth, inheriting diabolical desires from the devil their parent. Further it is the violent that seek after His soul; such as was Herod when he asked the chief priests where Christ should be born, such as was the whole synagogue when it bore false witness against Him. But in deeming this soul to be of human nature and weakness they set not God before their eyes; for God had stooped from that estate wherein He abode as God, even to the beginnings of human birth; that is, He became Son of Man Who before was the Son of God. For the Son of God is none other than He Who is Son of Man, and Son of Man not in partial measure but born so, the Form of God divesting Itself of that which It was and becoming that which It was not, that so It might be born into a soul and body of Its own. Hence He is both Son of God and Son of Man, hence both God and Man: in other words the Son of God was born with the attributes derived from human birth, the Nature of God condescending to assume the nature of one born as man who is wholly moulded of soul and flesh. Wherefore strangers, when they rise up against Him, and the mighty, when they seek after that soul of His, which in the Gospels is often sad and cast down, set not God before their eyes, because God it was, and the Son of God existing from out the ages, that was born with the attributes of human nature, was born as man, that is, with our body and our soul, by a virgin birth; the mighty and glorious works He wrought never opened their eyes to the fact that the Son of Man Whose soul they were seeking had come to be man with a beginning of life after an eternal existence as Son of God.
[AD 430] Augustine of Hippo on Psalms 54:3
"For aliens have risen up against me" [Psalm 54:3]. What "aliens"? Was not David himself a Jew of the tribe of Judah? But the very place Ziph belonged to the tribe of Judah; it was of the Jews. How then "aliens"? Not in city, not in tribe, not in kindred, but in flower.. ..But see the Ziphites, see them for a time flourishing. With reason "alien" sons. You amid the Ziphites hiding said what? "Blessed the people whereof the Lord is its God." Out of this affection this prayer is being sent forth into the ears of the Lord, when it is said, "for aliens have risen up against me."

[AD 367] Hilary of Poitiers on Psalms 54:4
The introduction of a pause marks a change of person. He no longer speaks but is addressed. For now the prophetic utterance assumes a general character. Thus immediately after the prayer addressed to God, he has added, in order that the confidence of the speaker might be understood to have obtained what He was asking even in the very moment of asking: Behold, God is My helper and the Lord is the upholder of My soul. He has requited evil unto Mine enemies. To each separate petition he has assigned its proper result, thus teaching us both that God does not neglect to hear, and that to look for a pledge of His pitifulness in hearing our several petitions is not a thing unreasonable. For to the words, For strangers are risen up against Me, the corresponding statement is: God is My helper; while with regard to and the violent have sought after My soul, the exact result of the hearing of His prayer is expressed in the words: and the Lord is the upholder of My soul; lastly the statement, they have not set God before their eyes, is appropriately balanced by, He has requited evil unto Mine enemies. Thus God both gives help against those that rise up, and upholds the soul of His Holy One when it is sought by the violent, and when He is not set before the eyes, nor considered by the ungodly, He requites upon His enemies the very evils which they had wrought; so that while without thinking upon God they seek the soul of the righteous and rise up against Him, He is saved and upheld, and they find that He Whom, absorbed in their wicked works, they did not consider, avenges their malice by turning it against themselves.

Let pure religion, therefore, have this confidence, and doubt not that amid the persecutions at the hand of man and the dangers to the soul, it still has God for its helper, knowing that, if at length it comes to a violent and unjust death, the soul on leaving the tabernacle of the body finds rest with God its upholder; let it have, moreover, perfect assurance of requital in the thought that all evil deeds return upon the heads of those that work them. God cannot be charged with injustice, and perfect goodness is unstained by the impulses and motions of an evil will. He does not awaken mischief out of malice, but requites it in vengeance; He does not inflict it because He wishes us ill, but He aims it against our sins. For these evils are universally appointed as instruments of retribution without destruction of life, such being the sternly just ordinance of that righteous judgment. But these evils are warded off from the righteous by the law of righteousness, and are turned back upon the unrighteous by the righteousness of that judgment. Each proceeding is equally just; for the righteous, because they are righteous, the warning exhibition of evil without actual infliction; for the wicked, because they so deserve, the punitive infliction of evil; the righteous will not suffer it, though it is displayed to them; the wicked will never cease to suffer it, because it is displayed to them.
[AD 430] Augustine of Hippo on Psalms 54:4
"For behold, God helps me" [Psalm 54:4]. Even themselves know not themselves, amid whom I am hiding. But if they too were to set God before their face, they would find in what manner God helps me. For all holy men are helped by God, but within, where no one sees. For in like manner as the conscience of ungodly men is a great punishment, so a great joy is the very conscience of godly men. "For our glory this is," says the Apostle, "the testimony of our conscience." [2 Corinthians 1:12] In this within, not in the flower of the Ziphites without, does glory that man that now says, "For behold God helps me." Surely though afar off are to be those things which He promises, this day have I a sweet and present help; today in my heart's joy I find that without cause certain say, "Who does show to us good things? For there is signed upon us the light of Your countenance, O Lord, You have put pleasantness into my heart." Not into my vineyard, not into my flock, not into my cask, not into my table, but "into my heart." "For behold God helps me." How does He help you? "And the Lord is the lifter up of my soul."

[AD 367] Hilary of Poitiers on Psalms 54:5
After this there is a return to the Person of God, to Whom the petition was at the first addressed: Destroy them by Your truth. Truth confounds falsehood, and lying is destroyed by truth. We have shown that the whole of the foregoing prayer is the utterance of that human nature in which the Son of God was born; so here it is the voice of human nature calling upon God the Father to destroy His enemies in His truth. What this truth is, stands beyond doubt; it is of course He Who said: I am the Life, the Way, the Truth. John 14:6 And the enemies were destroyed by the truth when, for all their attempts to win Christ's condemnation by false witness, they heard that He was risen from the dead and had to admit that He had resumed His glory in all the reality of Godhead. Ere long they found, in ruin and destruction by famine and war, their reward for crucifying God; for they condemned the Lord of Life to death, and paid no heed to God's truth displayed in Him through His glorious works. And thus the Truth of God destroyed them when He rose again to resume the majesty of His Father's Glory, and gave proof of the truth of that perfect Divinity which He possessed.

Now in view of our repeated, nay our unbroken assertion both that it was the Only-begotten Son of God Who was uplifted on the cross, and that He was condemned to death Who is eternal by virtue of the origin which is His by the nature which He derives from the eternal Father, it must be clearly understood that He was subjected to suffering of no natural necessity, but to accomplish the mystery of man's salvation; that He submitted to suffering of His own Will, and not under compulsion. And although this suffering did not belong to His nature as eternal Son, the immutability of God being proof against the assault of any derogatory disturbance, yet it was freely undertaken, and was intended to fulfil a penal function without, however, inflicting the pain of penalty upon the sufferer: not that the suffering in question was not of a kind to cause pain, but because the divine Nature feels no pain. God suffered, then, by voluntarily submitting to suffering; but although He underwent the sufferings in all the fullness of their force, which necessarily causes pain to the sufferers, yet He never so abandoned the powers of His Nature as to feel pain.
[AD 430] Augustine of Hippo on Psalms 54:5
"Turn away evil things unto mine enemies" [Psalm 54:5]. So however green they are, so however they flourish, for the fire they are being reserved. "In Your virtue destroy Thou them." Because to wit they flourish now, because to wit they spring up like grass: do not thou be a man unwise and foolish, so that by giving thought to these things thou perish for ever and ever. For, "Turn Thou away evil things unto mine enemies." For if you shall have place in the body of David Himself, in His virtue He will destroy them. These men flourish in the felicity of the world, perish in the virtue of God. Not in the same manner as they flourish, do they also perish: for they flourish for a time, perish for everlasting: flourish in unreal good things, perish in real torments. "In Your strength destroy," whom in Your weakness You have endured.

[AD 367] Hilary of Poitiers on Psalms 54:6
For next there follows: I will sacrifice unto You freely. The sacrifices of the Law, which consisted of whole burnt-offerings and oblations of goats and of bulls, did not involve an expression of free will, because the sentence of a curse was pronounced on all who broke the Law. Whoever failed to sacrifice laid himself open to the curse. And it was always necessary to go through the whole sacrificial action because the addition of a curse to the commandment forbad any trifling with the obligation of offering. It was from this curse that our Lord Jesus Christ redeemed us, when, as the Apostle says: Christ redeemed us from the curse of the law, being made curse for us, for it is written: cursed is every one that hangs on a tree. Galatians 3:13 Thus He offered Himself to the death of the accursed that He might break the curse of the Law, offering Himself voluntarily a victim to God the Father, in order that by means of a voluntary victim the curse which attended the discontinuance of the regular victim might be removed. Now of this sacrifice mention is made in another passage of the Psalms: Sacrifice and offering you would not, but a body have you prepared for Me ; that is, by offering to God the Father, Who refused the legal sacrifices, the acceptable offering of the body which He received. Of which offering the holy Apostle thus speaks: For this He did once for all when He offered Himself up Hebrews 7:27, securing complete salvation for the human race by the offering of this holy, perfect victim.
[AD 430] Augustine of Hippo on Psalms 54:6
"Voluntarily I will sacrifice to You" [Psalm 54:6]. Who can even understand this good thing of the heart, at another's speaking thereof, unless in himself he has tasted it? What is, "Voluntarily I will sacrifice to You"?... For what sacrifice here shall I take, brethren? Or what worthily shall I offer to the Lord for His mercy? Victims shall I seek from flock of sheep, ram shall I select, for any bull in the herds shall I look out, frankincense indeed from the land of the Sabæans shall I bring? What shall I do? What offer; except that whereof He speaks, "Sacrifice of praise shall honour Me"? Wherefore then "voluntarily"? Because truly I love that which I praise. I praise God, and in the self-same praise I rejoice: in the praise of Himself I rejoice, at whom being praised, I blush not. For He is not praised in the same manner as by those who love the theatrical follies is praised either by a charioteer, or a hunter, or actor of any kind, and by their praisers, other praisers are invited, are exhorted, to shout together: and when all have shouted, ofttimes, if their favourite is overcome, they are all put to the blush. Not so is our God: be He praised with the will, loved with charity: let it be gratuitous (or voluntary) that He is loved and that He is praised. What is "gratuitous"? Himself for the sake of Himself, not for the sake of something else. For if you praise God in order that He may give you something else, no longer freely do you love God. You would blush, if your wife for the sake of riches were to love you, and perchance if poverty should befall you, should begin to think of adultery. Seeing that therefore you would be loved by your partner freely, will you for anything else love God? What reward are you to receive of God, O covetous man? Not earth for you, but Himself He keeps, who made heaven and earth. "Voluntarily I will sacrifice to You:" do it not of necessity. For if for the sake of anything else you praise God, out of necessity you praise. These things also which He has given, because of the Giver are good things. For He gives entirely, He gives these temporal things: and to certain men to their good, to certain men to their harm, after the height and depth of His judgments...."Voluntarily I will sacrifice to You." Wherefore "voluntarily"? Because gratis. What is gratis? "And I will confess to Your name, O Lord, for it is a good thing:" for nothing else, but because a "good thing" it is. Does he say, "I will confess to Your name, O Lord," because You give me fruitful manors, because You give me gold and silver, because You give me extended riches, abundant money, most exalted dignity? Nay. But what? "For it is a good thing." Nothing I find better than Your name.

[AD 435] John Cassian on Psalms 54:6
For among them (the Egyptians) these offices, which we are taught to render to the Lord at separate hours and at intervals of time with a reminder from the convener, are celebrated freely and continuously throughout the whole day in conjunction with their work. For manual labor is continuously practiced by them in their cells in such a way that meditation on the Psalms and the rest of the Scriptures is always before them. To this at every moment they mingle short petitions and prayers, spending the whole day in those offices which we celebrate at fixed times. Thus, except for vespers and nocturns, there are no public services among them in the day except on Saturday and Sunday, when they meet together at the third hour for the purpose of Holy Communion. For what is continuously offered is greater than what is rendered at intervals of time. And a free gift is more acceptable than the duties which are performed by the compulsion of a rule. For such as this, David rejoices somewhat exultingly when he says, “Freely will I sacrifice to you;” and, “Let the free will offerings of my mouth be pleasing to you, O Lord.”

[AD 460] Valerian of Cimiez on Psalms 54:6
Listen to the prophet’s voice: “I will freely sacrifice to you, O Lord.” Learn how different an imposed servitude is from a voluntary one. A person who finds his own negligence accusing himself of suffering self-imposed servitude can never pass a day without regret. A person who obeys his Lord because of some solemn promise and thus reluctantly gains grace has stored up an injury for himself, since the prophet says, “Cursed is he who does the works of the Lord negligently.” If each one of you reflects on the wonderful gift of the acquired liberty that our Christ has granted to his faithful people through the regeneration of the life-giving bath [baptism] and through the pouring out of the Holy Spirit, he understands that God should not be served halfheartedly. Even though we daily give God whatever honor or gift we can, we never pay him all we owe.

[AD 367] Hilary of Poitiers on Psalms 54:7
Then He gives thanks to God the Father for the accomplishment of all these acts: I will give thanks unto Your name, O Lord, for it is good, for You have delivered Me out of all affliction. He has assigned to each clause its strict fulfilment. Thus at the beginning He had said: Save Me, O God, by Your name; after the prayers had been heard it was right that there should follow a corresponding ascription of thanks, in order that confession might be made to His name by Whose name He had prayed to be saved, and that inasmuch as He had asked for help against the strangers that rose up against Him, He might set on record that He had received it in the burst of joy expressed in the words: You have delivered Me out of all affliction. Then in respect of the fact that the violent in seeking after His soul did not set God before their eyes, He has declared His eternal possession of unchangeable divinity in the words: And My eye has looked down upon Mine enemies. For the Only-begotten Son of God was not cut off by death. It is true that in order to take the whole of our nature upon Him He submitted to death, that is to the apparent severance of soul and body, and made His way even to the realms below, the debt which man must manifestly pay: but He rose again and abides for ever and looks down with an eye that death cannot dim upon His enemies, being exalted unto the glory of God and born once more Son of God after becoming Son of Man, as He had been Son of God when He first became Son of Man, by the glory of His resurrection. He looks down upon His enemies to whom He once said: Destroy this temple, and in three days I will build it up. John 2:19 And so, now that this temple of His body has been built again, He surveys from His throne on high those who sought after His soul, and, set far beyond the power of human death, He looks down from heaven upon those who wrought His death, He who suffered death, yet could not die, the God-Man, our Lord Jesus Christ, Who is blessed for ever and ever. Amen.
[AD 430] Augustine of Hippo on Psalms 54:7
"For out of all tribulation You have delivered me" [Psalm 54:7]. For this cause I have perceived how good a thing is Your name: for if this I were able before tribulations to acknowledge, perchance for me there had been no need of them. But tribulation has been applied for admonition, admonition has redounded to Your praise. For I should not have understood where I was, except of my weakness I had been admonished. "Out of all tribulations," therefore, "You have delivered me. And upon mine enemies my eye has looked back:" upon those Ziphites "my eye has looked back." Yea, their flower I have passed over in loftiness of heart, unto You I have come, and thence I have looked back upon them, and have seen that "All flesh is grass, and all the glory of man as the flower of grass:" [Isaiah 40:6] as in a certain place is also said, "I have seen the ungodly man to be exalted and raised up like the cedars of Lebanon: I passed by, and, lo! He was not." Wherefore "he was not"? Because you have passed by. What is, "because you have passed by"? Because not to no purpose have you heard "Lift up your heart;" because not on earth, where you would have rotted, you have remained; because you have lifted your soul to God, and you have mounted beyond the cedars of Lebanon, and from that elevation hast observed: and "Lo! He was not;" and you have sought him, and there has not been found place for him. No longer is labour before you; because you have entered into the sanctuary of God, and hast understood for the last things. So also here thus he concludes. "And upon mine enemies my eye has looked back." This do ye therefore, brethren, with your souls; lift up your hearts, sharpen the edge of your mind, learn truly to love God, learn to despise the present world, learn voluntarily to sacrifice the offerings of praise; to the end that, mounting beyond the flower of the grass, you may look back upon your enemies.
