1 O God, thou art my God; early will I seek thee: my soul thirsteth for thee, my flesh longeth for thee in a dry and thirsty land, where no water is; 2 To see thy power and thy glory, so as I have seen thee in the sanctuary. 3 Because thy lovingkindness is better than life, my lips shall praise thee. 4 Thus will I bless thee while I live: I will lift up my hands in thy name. 5 My soul shall be satisfied as with marrow and fatness; and my mouth shall praise thee with joyful lips: 6 When I remember thee upon my bed, and meditate on thee in the night watches. 7 Because thou hast been my help, therefore in the shadow of thy wings will I rejoice. 8 My soul followeth hard after thee: thy right hand upholdeth me. 9 But those that seek my soul, to destroy it, shall go into the lower parts of the earth. 10 They shall fall by the sword: they shall be a portion for foxes. 11 But the king shall rejoice in God; every one that sweareth by him shall glory: but the mouth of them that speak lies shall be stopped.
[AD 430] Augustine of Hippo on Psalms 63:1
"God, my God, unto You from the light I watch" [Psalm 63:1]. What is to watch? It is, not to sleep. What is to sleep? There is a sleep of the soul; there is a sleep of the body. Sleep of body we all ought to have: because if sleep of body is not taken, a man faints, the body itself faints. For our frail body cannot long sustain a soul watching and on the stretch on active works; if for a long time the soul shall have been intent on active pursuits, the body being frail and earthly holds her not, sustains her not for ever in activity, and faints and falls. Therefore God has granted sleep to the body, whereby are recruited the members of the body, in order that they may be able to sustain the soul watching. But of this let us take heed, namely, that our soul herself sleep not: for evil is the sleep of the soul. Good is the sleep of the body, whereby is recruited the health of the body. But the sleep of the soul is to forget her God. Whatsoever soul shall have forgotten her God, sleeps. Therefore the Apostle says to certain persons that forgot their God, and being as it were in sleep, did act the follies of the worship of idols— the Apostle, I say, says to certain persons, "Rise, you that sleepest, and rise up from the dead, and Christ shall enlighten you." [Ephesians 5:14] Was the Apostle waking up one sleeping in body? Nay, but he was waking a soul sleeping, inasmuch as he was waking her, in order that she might be lightened by Christ. Therefore as to these same watchings says this man, "God, my God, unto You from the light I watch." For you would not watch of yourself, unless there should arise your Light, to wake you from sleep. For Christ lightens souls, and makes them to watch: but if His light He takes away, they slumber. For for this cause to Him there is said in another psalm, "Lighten my eyes, that I may never slumber in death.". ..

[AD 465] Maximus of Turin on Psalms 63:1-4
Therefore God gave us a pattern of fasting in this deed, so that having a desert, as it were, at the time of fasting we may abstain from feasts, pleasure and women, and so that Eve may not be joined with us so as to subvert us from chaste observance by her alluring persuasion. For he who fasts and is chaste at the time of the 40-day fast2 seems somehow to dwell in the desert. Clearly, that certain desert is the body of a Christian when it is not filled with food or watered with drinks, but is neglected by the squalor of thirsty starvation. The desert, I say, is our body when the flesh begins to grow weaker by abstinence, when pallor is overcome by thirst, and the unadorned appearance of the whole human being becomes dirty by the contempt of material things. Then Christ the Lord dwells in the desert of our body, when he has discovered our land squalid in hunger and dry by thirst, just as that adage which the prophet David says, “Just like in a deserted land where there are neither roads nor water, so I appeared in your sanctuary.” For we are not able to appear to him in the sanctuary in any other way, unless the land of our body has been made desert from worldly delights and without the roads made by devilish desires and without the water from libidinous allurements. Then the Savior, dwelling in this desert of our body, conquers all the factions of the devil and makes our body his own dwelling, safe and secure from the thoughts of this age, so that we may be constituted in solitude within our very selves, as it were, and see nothing but heaven and earth. That is to say, we think about nothing other than the Lord of the heavenly kingdom and the author of the earthly resurrection.

[AD 430] Augustine of Hippo on Psalms 63:2
"My soul has thirsted for You" [Psalm 63:2]. Behold that desert of Idumæa. See how here he thirsts: but see what good thing is here, "Hath thirsted for You." For there are they that thirst, but not for God. For every one that wills anything to be granted to him, is in the heat of longing; the longing itself is the thirst of the soul. And see ye what longings there are in the hearts of men: one longs for gold, another longs for silver, another longs for possessions, another inheritance, another abundance of money, another many herds, another a wife, another honours, another sons. You see those longings, how they are in the hearts of men. All men are inflamed with longing, and scarce is found one to say, "My soul has thirsted for You." For men thirst for the world: and perceive not themselves to be in the desert of Idumæa, where their souls ought to thirst for God....

[AD 430] Augustine of Hippo on Psalms 63:3
"Thus in a holy thing I have appeared to You, that I might see Your power and Your glory" [Psalm 63:3]....Unless a man first thirst in that desert, that is in the evil wherein he is, he never arrives at the good, which is God. But "I have appeared to You," he says, "in a holy thing." Now in a holy thing is there great consolation. "I have appeared to You," is what? In order that You might see me: and for this reason You have seen me, in order that I might see You. "I have appeared to You, that I might see." He has not said, "I have appeared to You, that You might see:" but, "I have appeared to You, that I might see Your power and Your glory." Whence also the Apostle, "But now," he says, "knowing God, nay, having been known of God." [Galatians 4:9] For first you have appeared to God, in order that to you God might be able to appear. "That I might see Your power and Your glory." In truth in that forsaken place, that is, in that desert, if as though from the desert a man strives to obtain enough for his sustenance, he will never see the power of the Lord, and the glory of the Lord, but he will remain to die of thirst, and will find neither way, nor consolation, nor water, whereby he may endure in the desert. But when he shall have lifted up himself to God, so as to say to Him out of all his inward parts, "My soul has thirsted for You; how manifoldly for You also my flesh!" lest perchance even the things necessary for the flesh of others he ask, and not of God, or else long not for that resurrection of the flesh, which God has promised to us: when, I say, he shall have lifted up himself, he will have no small consolations.

[AD 397] Ambrose of Milan on Psalms 63:5-9
Now let us turn our attention to the characteristic of fatness or richness of which David speaks intelligibly when he says, “Let my soul be filled as with marrow and fatness.” Before that he had said, “And may your whole burnt offering be made fat.” By this he means that the requirements for a sacrifice are that it be fat or rich, that it be glistening and that it be weighted with the sustenance inspired by faith and devotion and by the rich nourishment of the Word of God. Frequently we use the word fat or rich when we refer to something that is heavily and elaborately adorned, and to the finest victim as one that is not thin and scrawny. Wherefore we designate as “rich” a sacrifice that we desire to be regarded as the “finest.” We also have proof of this when we consult the prophetic passage in the Scriptures where fine cows are compared with years of fertility!

[AD 407] John Chrysostom on Psalms 63:5-9
Why do we forget about wickedness? It is due to our remembrance of good things, due to our remembrance of God. If we continually remember God, we cannot remember those things also. For [he says], “When I remembered you on my bed, I thought on you in the morning dawn.” We ought then to have God always in remembrance, but then especially, when thought is undisturbed, when by means of that remembrance [one] is able to condemn himself, when he can retain [things] in memory. For in the daytime indeed, if we do remember, other cares and troubles entering in, drive the thought out again; but in the night it is possible to remember continually, when the soul is calm and at rest; when it is in the heaven, and under a serene sky. “The things that you say in your hearts you should grieve over on your beds,” he says. For it was indeed right to remember this throughout the day also. But inasmuch as you are always full of cares and distracted amid the things of this life, at least then remember God on your bed; at the morning dawn meditate on him.

[AD 430] Augustine of Hippo on Psalms 63:5
"So I will speak good of You in my life, and in Your name I will lift up my hands" [Psalm 63:5]. Now in my life which to me You have given, not in that which I have chosen after the world with the rest among many lives, but that which You have given to me through Your mercy, that I should praise You. "So I will speak good of You in my life." What is "so"? That to Your mercy I may ascribe my life wherein You I praise, not to my merits. "And in Your name I will lift up my hands." Lift up therefore hands in prayer. Our Lord has lifted up for us His hands on the Cross, and stretched out were His hands for us, and therefore were His hands stretched out on the Cross, in order that our hands might be stretched out unto good works: because His Cross has brought us mercy. Behold, He has lifted up hands, and has offered for us Himself a Sacrifice to God, and through that Sacrifice have been effaced all our sins. Let us also lift up our hands to God in prayer: and our hands being lifted up to God shall not be confounded, if they be exercised in good works. For what does he that lifts up hands? Whence has it been commanded that with hands lifted up we should pray to God? For the Apostle says, "Lifting up pure hands without anger and dissension." [1 Timothy 2:8] It is in order that when you lift up hands to God, there may come into your mind your works. For whereas those hands are lifted up that you may obtain that which you will, those same hands you think in good works to exercise, that they may not blush to be lifted up to God. "In your name I will lift up my hands." Those are our prayers in this Idumæa, in this desert, in the land without water and without way, where for us Christ is the Way, [John 14:6] but not the way of this earth.

[AD 523] Philoxenus of Mabbug on Psalms 63:5-9
Pure prayer such as is worthy of God, O disciple of God, is not uttered by means of compound words. Prayer that is worthy of God consists in this: that one gather in one’s mind from the entire world and not let it be secretly bound to anything; that one place it entirely at God’s disposal and forget, during the time of prayer, everything that is material, including one’s own self and the place where one is standing. One should be secretly swallowed up in the spirit of God, and one should clothe oneself in God at the time of prayer both outwardly and inwardly, set on fire with ardent love for him and entirely engulfed in his thoughts of God, entirely commingled in all of him, with the movements of one’s thoughts suffused with wondrous recollection of God, while the soul has gone out in love to seek him whom it loves, just as David said, “My soul has gone out after you.”

[AD 430] Augustine of Hippo on Psalms 63:7-8
"If I have remembered You upon my bed, in the dawnings I did meditate on you [Psalm 63:7]: because You have become my helper" [Psalm 63:8]. His "bed" he calls his rest. When any one is at rest, let him be mindful of God; when any one is at rest, let him not by rest be dissolved, and forget God: if mindful he is of God when he is at rest, in his actions on God he does meditate. For the dawn he has called actions, because every man at dawn begins to do something. What therefore has he said? If therefore I was not mindful on my bed, in the dawn also I did not meditate on You. Can he that thinks not of God when he is at leisure, in his actions think of God? But he that is mindful of Him when he is at rest, on the Same does meditate when he is doing, lest in action he should come short. Therefore he has added what? "Because You have become my helper." For unless God aid our good works, they cannot be accomplished by us. And worthy things we ought to work: that is, as though in the light, since by Christ showing the way we work. Whosoever works evil things, in the night he works, not in the dawn; according to the Apostle, saying, "They that are drunken, in the night are drunken; and they that sleep, in the night do sleep; let us that are of the day, be sober." [1 Thessalonians 5:7-8] He exhorts us that after the day we should walk honestly: "As in the day, honestly let us walk." [Romans 13:13] And again, "You," he says, "are sons of light, and sons of day; we are not of night nor of darkness." [1 Thessalonians 5:5] Who are sons of night, and sons of darkness? They that work all evil things. To such a degree they are sons of night, that they fear lest the things which they work should be seen....No one therefore in the dawn works, except him that in Christ works. But he that while at leisure is mindful of Christ, on the Same does meditate in all his actions, and He is a helper to him in a good work, lest through his weakness he fail. "And in the covering of Your wings I will exult." I am cheerful in good works, because over me is the covering of Your wings. If you protect me not, forasmuch as I am a chicken, the kite will seize me. For our Lord Himself says in a certain place to that Jerusalem, a certain city, where He was crucified: "Jerusalem," He says, "Jerusalem, how often I have willed to gather your sons, as though a hen her chickens, and you would not." [Matthew 23:37] Little ones we are: therefore may God protect us under the shadow of His wings. What when we shall have grown greater? A good thing it is for us that even then He should protect us, so that under Him the greater, always we be chickens. For always He is greater, however much we may have grown. Let no one say, let Him protect me while I am a little one: as if sometime he would attain to such magnitude, as should be self-sufficient. Without the protection of God, nought you are. Alway by Him let us desire to be protected: then always in Him we shall have power to be great, if always under Him little we be. "And in the covering of Your wings I will exult."

[AD 430] Augustine of Hippo on Psalms 63:9
"But themselves in vain have sought my soul. They shall go unto the lower places of the earth" [Psalm 63:9]. Earth they were unwilling to lose, when they crucified Christ: into the lower places of the earth they have gone. What are the lower places of the earth? Earthly lusts. Better it is to walk upon earth, than by lust to go under earth. For every one that in prejudice of his salvation desires earthly things, is under the earth: because earth he has put before him, earth upon himself he has put, and himself beneath he has laid. They therefore fearing to lose earth, said what of the Lord Jesus Christ, when they saw great multitudes go after Him, forasmuch as He was doing wonderful things? "If we shall have let Him go alive, there will come the Romans, and will take away from us both place and nation." [John 11:48] They feared to lose earth, and they went under the earth: there befell them even what they feared. For they willed to kill Christ, that they might not lose earth; and earth they therefore lost, because Christ they slew. For when Christ had been slain, because the Lord Himself had said to them, "The kingdom shall be taken from you, and shall be given up to a nation doing righteousness:" [Matthew 21:43] there followed them great calamities of persecutions: there conquered them Roman emperors, and kings of the nations: they were shut out from that very place where they crucified Christ, and now that place is full of Christian praisers: it has no Jew, it has been cleared of the enemies of Christ, it has been fulfilled with the praisers of Christ. Behold, they have lost at the hands of the Romans the place, because Christ they slew, who to this end slew, that they might not lose the place at the hands of the Romans. Therefore, "They shall enter into the lower places of the earth."

[AD 430] Augustine of Hippo on Psalms 63:10
"They shall be delivered unto the hands of the sword" [Psalm 63:10]. In truth, thus it has visibly befallen them, they have been taken by storm by enemies breaking in. "Portions of foxes they shall be." Foxes he calls the kings of the world, that then were when Judæa was conquered. Hear in order that you may know and perceive, that those he calls foxes. Herod the king the Lord Himself has called a fox. "Go," He says, "and tell that fox." [Luke 13:32] See and observe, my brethren: Christ as King they would not have, and portions of foxes they have been made. For when Pilate the deputy governor in Judæa slew Christ at the voices of the Jews, he said to the same Jews, "Your King shall I crucify?" [John 19:15] Because He was called King of the Jews, and He was the true King. And they rejecting Christ said, "We have no king but Cæsar." They rejected a Lamb, chose a fox: deservedly portions of foxes they were made.
