1. Samuel 27:8

From Ziklag David made an attack upon the Geshurites, Gerzites, and Amalekites, smote them without leaving a man alive, and returned with much booty. The occasion of this attack is not mentioned, as being a matter of indifference in relation to the chief object of the history; but it is no doubt to be sought for in plundering incursions made by these tribes into the land of Israel. For David would hardly have entered upon such a war in the situation in which he was placed at that time without some such occasion, seeing that it would be almost sure to bring him into suspicion with Achish, and endanger his safety. ויּעל, "he advanced," the verb being used, as it frequently is, to denote the advance of an army against a people or town (see at Jos 8:1). At the same time, the tribes which he attacked may have had their seat upon the mountain plateau in the northern portion of the desert of Paran, so that David was obliged to march up to reach them. פּשׁט, to invade for the purpose of devastation and plunder. Geshuri is a tribe mentioned in Jos 13:2 as living in the south of the territory of the Philistines, and is a different tribe from the Geshurites in the north-east of Gilead (Jos 12:5; Jos 13:11, Jos 13:13; Deu 3:14). These are the only passages in which they are mentioned. The Gerzites, or Gizrites according to the Keri, are entirely unknown. Bonfrere and Clericus suppose them to be the Gerreni spoken of in 2 Macc. 13:24, who inhabited the town of Gerra, between Rhinocolura and Pelusium (Strabo, xvi. 760), or Gerron (Ptol. iv. 5). This conjecture is a possible one, but is very uncertain nevertheless, as the Gerzites certainly dwelt somewhere in the desert of Arabia. At any rate Grotius and Ewald cannot be correct in their opinion that they were the inhabitants of Gezer…

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 h…

27:8 Geshurites . . . Girzites . . . Amalekites: These groups, who lived on the edges of the southern desert, had been troublesome to both Philistines and Israelites. (On the Amalekites, see 14:48; ch 15; on the Geshurites, see Josh 13:2, 13; 2 Sam 3:3.) • Shur was somewhere east of Egypt (1 Sam 15:7; Gen 16:7; 20:1; 25:18).
