Here is an account of David's actions while he was in the land of the Philistines, a fierce attack he made upon some remains of the devoted nations, his success in it, and the representation he gave of it to Achish. 1. We may acquit him of injustice and cruelty in this action because those people whom he cut off were such as heaven had long since doomed to destruction, and he that did it was one whom heaven had ordained to dominion; so that the thing was very fit to be done, and he was very fit to do it. It was not for him that was anointed to fight the Lord's battles to sit still in sloth, however he might think fit, in modesty, to retire. He desired to be safe from Saul only that he might expose himself for Israel. He avenged an old quarrel that God had with these nations, and at the same time fetched in provisions for himself and his army, for by their swords they must live. The Amalekites were to be all cut off. Probably the Geshurites and Gezrites were branches of Amalek. Saul was rejected for sparing them, David makes up the deficiency of his obedience before he succeeds him. He smote them, and left none alive, Sa1 27:8, Sa1 27:9. The service paid itself, for they carried off abundance of spoil, which served for the subsistence of David's forces. 2. Yet we cannot acquit him of dissimulation with Achish in the account he gave him of this expedition. (1.) David, it seems, was not willing that he should know the truth, and therefore spared none to carry tidings to Gath (Sa1 27:11), not because he was ashamed of what he had done as a bad thing, but because he was afraid, if the Philistines knew it, they would be apprehensive of danger to themselves or their allies by harbouring him among them and would expel him from their coasts. It would be easy to conclude, If so he did, so will be his manner, and therefore he industriously conceals it from them, which, it seems, he could do by putting them all to the sword, for none of their neighbours would inform against him, nor perhaps would soon come to the knowledge of what was done, intelligence not being so readily communicated then as now. (2.) He hid it from Achish with an equivocation not at all becoming his character. Being asked which way he had made his sally, he answered, Against the south of Judah, v. 13. It was true he had invaded those countries that lay south of Judah, but he made Achish believe he had invaded those that lay south in Judah, the Ziphites for example, that had once and again betrayed him; so Achish understood him, and thence inferred that he had made his people Israel to abhor him, and so riveted himself in the interest of Achish. The fidelity of Achish to him, his good opinion of him, and the confidence he put in him, aggravate his sin in deceiving him thus, which, with some other such instances, David seems penitently to reflect upon when he prays, Remove from me the way of lying.

Achish gave him Ziklag - Ziklag was at first given to the tribe of Judah, but afterwards it was ceded to that of Simeon, Jos 15:31; Jos 19:5. The Philistines had, however, made themselves masters of it, and held it to the time here mentioned; it then fell into the tribe of Judah again, and continued to be the property of the kings of Judah. This verse is a proof that this book was written long after the days of Samuel, and that it was formed by a later hand, out of materials which had been collected by a contemporary author. See the preface.

And David and his men went up,.... From Ziklag, where they dwelt:

and invaded the Geshurites; some of the old inhabitants of the land of Canaan, the remains of the Amorites, whose land was given to the half tribe of Manasseh, but could never be expelled; and therefore David had a just right to invade them, and, if he could, either expel or destroy them; see Deu 3:14; these are the Geshurites which are joined with the Philistines, Jos 13:2,

and the Gezrites; the inhabitants of Gezer, which place fell to the tribe of Ephraim; but that tribe could not drive out the inhabitants of it, and therefore David now fell upon them as the enemies of Israel, and seized on their country, as belonging to them, Jos 16:3,

and the Amalekites; the sworn and implacable enemies of Israel, and whose memory they were laid under obligation to root out. These were such as had escaped the sword of Saul, and had fled to the more distant parts, against whom David now went; and perhaps these had fled to and mixed themselves with the people here mentioned:

for these nations were of old the inhabitants of the land; of the land of Canaan:

as thou goest to Shur, even unto the land of Egypt; see Sa1 15:7.

David . . . went up, and invaded the Geshurites--(See Jos 13:2).

and the Gezrites--or the Gerizi [GESENIUS], (Jos 12:12), some Arab horde which had once encamped there.

and the Amalekites--Part of the district occupied by them lay on the south of the land of Israel (Jdg 5:14; Jdg 12:15).
