(6) Surely, as the Lord liveth.--This seems a strange oath for an idolatrous prince like the King of Gath to make use of--"By the life of Jehovah." It was probably the equivalent of the real oath of Achish, unless, as Keil supposes, the Philistine friend of David, in his oath, used the formula which he thought would be most acceptable to David, whom he looked upon as injured falsely by the suspicion of the Philistine leaders.

Verses 6, 7. - As Jehovah liveth. These words are strange in the mouth of a Philistine, nor can we suppose that out of respect to David he would thus swear by David's God. Probably they are the equivalent of the oath which Achish really used. He sends, however, David away with the utmost courtesy, assuring him that his own wish had been that he should remain with him, because all his conduct had been upright since he had come to him at Gath.

29:6-11 David scarcely ever had a greater deliverance than when dismissed from such insnaring service. God's people should always behave themselves so, as, if possible, to get the good word of all they have dealings with: and it is due to those who have acted well, to speak well of them.Then Achish called David,.... Being so near him, that he could call unto him himself, or he sent some person to him, to require his presence with him:

and said unto him, surely, as the Lord liveth; or "Jehovah liveth"; an oath by the true God, of whom Achish might have some knowledge, as he also had of angels, from his conversation with David; though the Heathens had a notion of a supreme Being, and yet worshipped other gods, and whom they called Jove, from this name of Jehovah. Kimchi observes, that all confess a first cause; and therefore when he swore to David, he swore by him in whom David believed, perhaps out of complaisance to him, or that David might pay the greater regard to his oath:

thou hast been upright; sincere, honest, faithful, and just in all his deportment; yet not so sincere as he thought him to be, witness the road he pretended he had taken against the south of Judah, 1 Samuel 27:1,

and thy going out and thy coming in with me in the host is good in sight; his behaviour in the army, attending him as the keeper of his head, or captain of his bodyguard, was exceeding agreeable to him, and he could wish to have him continued:

for I have not found evil in thee, since the day of thy coming unto me unto this day; whatever he had done before to the Philistines, having greatly afflicted and distressed them in his wars with them, of which this seems to be an exception:

nevertheless, the lords favour thee not; or thou art not acceptable to them, yea, very offensive and disagreeable.
