1 And David said in his heart, I shall now perish one day by the hand of Saul: there is nothing better for me than that I should speedily escape into the land of the Philistines; and Saul shall despair of me, to seek me any more in any coast of Israel: so shall I escape out of his hand. 2 And David arose, and he passed over with the six hundred men that were with him unto Achish, the son of Maoch, king of Gath. 3 And David dwelt with Achish at Gath, he and his men, every man with his household, even David with his two wives, Ahinoam the Jezreelitess, and Abigail the Carmelitess, Nabal's wife. 4 And it was told Saul that David was fled to Gath: and he sought no more again for him. 5 And David said unto Achish, If I have now found grace in thine eyes, let them give me a place in some town in the country, that I may dwell there: for why should thy servant dwell in the royal city with thee? 6 Then Achish gave him Ziklag that day: wherefore Ziklag pertaineth unto the kings of Judah unto this day. 7 And the time that David dwelt in the country of the Philistines was a full year and four months. 8 And David and his men went up, and invaded the Geshurites, and the Gezrites, and the Amalekites: for those nations were of old the inhabitants of the land, as thou goest to Shur, even unto the land of Egypt. 9 And David smote the land, and left neither man nor woman alive, and took away the sheep, and the oxen, and the asses, and the camels, and the apparel, and returned, and came to Achish. 10 And Achish said, Whither have ye made a road to day? And David said, Against the south of Judah, and against the south of the Jerahmeelites, and against the south of the Kenites. 11 And David saved neither man nor woman alive, to bring tidings to Gath, saying, Lest they should tell on us, saying, So did David, and so will be his manner all the while he dwelleth in the country of the Philistines. 12 And Achish believed David, saying, He hath made his people Israel utterly to abhor him; therefore he shall be my servant for ever.
[AD 430] Augustine of Hippo on 1 Samuel 27:2
“What,” you say, “have you to do with the kings of this world, in whom Christianity has never found anything save envy toward it?” Having said this, you endeavored to reckon up what kings the righteous had found to be their enemies, and [you] did not consider how many more might be enumerated who have proved their friends. The patriarch Abraham was both most friendly treated, and presented with a token of friendship, by a king who had been warned from heaven not to defile his wife. Isaac his son likewise found a king most friendly to him. Jacob, being received with honor by a king in Egypt, went so far as to bless him. What shall I say of his son Joseph, who, after the tribulation of a prison, in which his chastity was tried as gold is tried in the fire, being raised by Pharaoh to great honors, even swore by the life of Pharaoh4—not as though puffed up with vain conceit but being not unmindful of his kindness. The daughter of a king adopted Moses. David took refuge with a king of another race, compelled thereto by the unrighteousness of the king of Israel.

[AD 585] Cassiodorus on 1 Samuel 27:1-3
“When the Philistines held him in Gath”; this is recounted in the text of the book of Kings [Samuel]. David was terrorized by attacks of Saul and thought that he would be hidden in the city of Gath among the Philistines. But we have said that all this is to be explained as mystical allegory. Gath denotes “winepress,” the squeezing which every Christian endures, but then he makes the harvest most abundant when he has been pressed by the rods of afflictions. So the church reasonably and appropriately speaks in this heading. Though weighed down by the persecutions of the Philistines, that is, by outsiders, [the church] pours forth the deserving merits of its saints with abundant freedom as though they were liquid nectar.

[AD 735] Bede on 1 Samuel 27:10
But Achis said to him: Against whom have you made a raid today? etc. Although he seems to deceive in the literal sense, who, rising against the Philistines, devastating the province not far from them, said he had made a raid against the one who arouses their king against his own people: yet the figure of speech does not deceive, because while he draws the nations to faith, Christ arises against the clear and burning blasphemy of the Jews. For by His just judgement, blindness in part has happened to Israel, until the fullness of the Gentiles has come in, and thus all Israel shall be saved (Rom. XI): therefore, while bringing in the nations, He rises against Judea, which, out of pride, broke not a few branches of the good olive tree, so that by grafting in the wild olive tree, He might make it a partaker of the good root and fatness of the olive tree. And it is well said to be a rising against, because He who falls, says He, upon this rock, will be broken; but on whomsoever it shall fall, it will grind him to powder (Luke XX).

[AD 735] Bede on 1 Samuel 27:8
And David and his men went up, etc. Upon the rock, Egypt sounds darkness. Therefore, the Church was growing through the steadfastness of Christ's disciples, and was rescuing souls from pagan rites, which, following the examples of not new but ancient men, had clung to earthly desires, with all going to the hardness of heart, and arriving as far as the dark land, covered with the gloom of death, the land of the misery of darkness, where the shadow of death, and no order, and eternal horror dwells.

[AD 735] Bede on 1 Samuel 27:2
And David arose, and he went himself, etc. The Lord leaves the seat which He used to hold in the hearts of the Jews from ancient times and went to acquire the Gentiles for His faith, He himself and the ministers of His word, notable by their multiplicity, that is, intent on perfect work in this present time, and suspended in their mind by the undoubted hope of heavenly things in the future.

[AD 735] Bede on 1 Samuel 27:12
Therefore Achish believed in David, etc. The entire fraternity of the nations believes in Christ, saying that the people in which He was born He abandoned due to their infidelity; and because of this infidelity, threw down so many branches of the good olive tree, so that by believing it might graft itself in, and cast those to be burned into the fire. Indeed, for me now believing, hoping, loving, He is the debtor of eternal life; so that without Him I can do nothing, both in the present the pledge of the Spirit, and in the future He will provide me with the eternal grace of His protection. Concerning this perpetual servitude bestowed upon faithful servants by God the Lord, the Lord Himself says: Amen I say to you, He will gird Himself, and will make them sit down to eat, and passing will minister to them (Luke XII).

[AD 735] Bede on 1 Samuel 27:9
And David struck all the land, etc. The Lord strikes with the sword of His word whatever earthly and lowly thing He finds in unbelievers; nor does He allow anyone of those who truly receive the faith, either in spirit or in flesh, to live further in their prior conduct, but makes all by true confession say with the Apostle: But it is no longer I who live, but Christ lives in me (Gal. II).

[AD 735] Bede on 1 Samuel 27:9
And he took the sheep and the cattle, etc. Christ, taking from the nations souls of diverse character, hastens to gather them all into the unity of the preexisting Church in Himself.

[AD 735] Bede on 1 Samuel 27:3
He was from the tribe of Caleb. The teachers of the synagogue were from the disciples of the lawgiver. For the scribes and Pharisees sat on Moses' seat (Matthew XXIII); who, since they then led other mortals by the grace of both human and divine wisdom, can, not unjustly, be called Caleb, that is, the whole heart; or because we read that patriarch Caleb was powerful in faith and virtue, we can say that the faithfulness of the faithful is the increase of damnation for the faithless, who have degenerated from the life of their parents.

[AD 735] Bede on 1 Samuel 27:3
And David dwelt with Achish in Gath, etc. Gath, which is translated as winepress, signifies the pressures and tribulations by which the faith of the Church is tested in this life; as also the Psalms, which are titled for the winepresses, declare. Achish, who is called Brother of man, signifies the people of the nations who, by believing in Christ, rejoice to be his brother through grace, and to act manfully. For Maoch, his father, who is translated into emasculation, that is, deprived of manly action, mind, and virtue, demonstrates the Gentiles of earlier times, who, serving idols, remained void both of the work and reward of virtue. Therefore, the Lord dwelt among the nations first in persecutions and very great pressures, until they themselves could know to accept his faith; he and his apostles: every shepherd, with the Church subjected to him which he governs and educates; Christ himself as the one shepherd of twin flocks, namely those he brought from the Gentiles, and those from the Jews dispersed in the day of gloom and cloud, whom he does not cease to preserve and feed among the nations. David’s two wives can also be understood as the chaste souls of the faithful, adhering to Christ in the lifestyle of two ways of life, namely active and contemplative. Ahinoam the Jezreelite, that is, my brother’s beauty, deriving origin from the seed of God, may be she whose eyes of an enlightened mind burn with all their strength to see the King in his beauty. Abigail, on the other hand, that is, my Father’s exultation; the wife of Nabal the Carmelite, that is, the foolish and soft one, can be understood as she who, recently saved by repentance from the blandishments of a foolish teacher, brings such joy in the Father in heaven along with the angels, more than over the ninety-nine righteous who do not need repentance.

[AD 735] Bede on 1 Samuel 27:4
And Saul added no more to seek him. This signifies the present time of the Church; when the Jews, seeing it glorified among the nations, and also protected by the favor of secular kings, although they do not cease to hate it, have nevertheless lost all hope and intention of overcoming it altogether.

[AD 735] Bede on 1 Samuel 27:6
Therefore Achis gave him on that day Siceleg, etc. Siceleg is interpreted as the purification of a raised voice; but to purify a voice is to bring a voice to itself, with careful discretion, to inquire which speech smells of truth, which of falsehood. Therefore, the believers from the Gentiles gave to Christ, to dedicate their dwelling, which is understood as the Church, throngs of souls who, coming to themselves from the voices of preachers, knew how to discern, by reason, and to separate the purity of the apostolic voice from the dregs of the philosophical or pagan voice. For this reason, such assemblies of souls, having been withdrawn from gentile ceremonies, have become subject in perpetuity to the authority of the apostles. This sense, I believe, is also aided by the history of Josephus in the Antiquities (Book XVI, Chapter 13), which says: "To whom the king gave a certain village called Siceleg. This village he so loved, that when David reigned, he and his men honored it as their own possession."

[AD 735] Bede on 1 Samuel 27:5
But David said to Achis, "If I have found favor in your eyes," etc. The Lord said through his disciples to the Gentile people: "If the doctrine of truth, which I preach, and the life which I promise, are pleasing to you, let a humble heart of the listeners be given to my words in the firm unity of the faithful, where I dwell by the grace of the Holy Spirit."

[AD 735] Bede on 1 Samuel 27:11
David did not bring to life a man and a woman, etc. Christ forbids those converted to Him from living in sins. Just as first showing this to the teacher of His Church, He commands the multitudes of impure hearts, saying: Rise, Peter, kill and eat (Acts X). And Paul teaches that they are not dead to sin, but living to God in Christ Jesus (Ephesians II). But neither does He now command believers to undergo martyrdom or deaths for His name from the impious.

[AD 735] Bede on 1 Samuel 27:11
Saying, Lest perhaps they speak, etc. Therefore, he did not bring to life, lest they speak against him. For the listener bears witness against his teacher, who, less perfectly educated either in believing or in acting, shows himself less extinguished by improper action or thought.

[AD 735] Bede on 1 Samuel 27:7
Now the number of days that David lived in the land of the Philistines, etc. There was, is, and will be a time of Christ's dwelling in the Church of the Gentiles, until he fills the four corners of the world with the complete light of his heavenly grace, until he pours the light of the Gospel, which is contained in the unanimous variety of the four books, into the believing hearts of the Gentiles. And note that David, coming to the Philistines, begins to dwell in Geth; but soon, with Achis' permission, he turns to Siceleg: because, coming to the Gentiles in the disciples, Christ, first pressed by the winepress of pressures by the unbelievers, finally after many grapes of the martyrs pressed, he approached to instruct those who among the dregs and wine of intellectual innkeepers, that is, those teaching various senses, knew how to judge.

[AD 1781] Richard Challoner on 1 Samuel 27:8
Pillaged Gessuri: These probably were enemies of the people of God: and some, if not all of them, were of the number of those whom God had ordered to be destroyed: which justifies David's proceedings in their regard. Though it is to be observed here, that we are not under an obligation of justifying every thing that he did: for the scripture, in relating what was done, does not say that it was well done. And even such as are true servants of God, are not to be imitated in all they do.
