1 Kings (1 Samuel) 29:2
sa1 29:2With Achish - As the life - guard of Achish. Achish being, as it seems, the general of the army.
1 Kings (1 Samuel) 29:3
sa1 29:3The princes - The Lords of the other eminent cities, who were confederate with him in this expedition. These days or years - That is, did I say days? I might have said years. He hath now been with me a full year and four months, Sa1 27:7, and he was with me some years ago, Sa1 21:10, and since their time hath been known to me. And it is not improbable, but David, after his escape from thence, might hold some correspondence with Achish, as finding him to be a man of a more generous temper than the rest of the Philistines, and supposing that he might have need of him for a refuge, in case Saul continued to seek his life. Since he fell - Revolted, or left his own king to turn to me.
1 Kings (1 Samuel) 29:4
sa1 29:4Make this fellow - Herein the wise and gracious providence of God appeared, both in helping him out of these difficulties, out of which no human wit could have extricated him, but he must have been, an ungrateful person either to the one or the other side, and moreover in giving him the happy opportunity of recovering his own, and his all from the Amalekites, which had been irrecoverably lost, if he had gone into this battle.

1 Kings (1 Samuel) 29:8

1 Kings (1 Samuel) 29:9
sa1 29:9Angel of God - In whom nothing is blame - worthy. The Heathens acknowledged good spirits, which also they worshipped as an inferior sort of deities, who were messengers and ministers to the supreme God; Achish had learned the title of angels, from the Israelites his neighbours, and especially from David's conversation.
1 Kings (1 Samuel) 29:11
sa1 29:11Rose up early - David did not then know, how necessary this was, for the relief of his own city. But God knew it well, and sent him thither accordingly. On how many occasions may he say, What I do thou knowest not now; but thou shalt know hereafter?
