2 As the Philistine warlords marched forward by regiments and divisions, David and his men were bringing up the rear with Achish. 3 The Philistine officers said, "What business do these Hebrews have being here?" Achish answered the officers, "Don't you recognize David, ex-servant of King Saul of Israel? He's been with me a long time. I've found nothing to be suspicious of, nothing to complain about, from the day he defected from Saul until now." 4 Angry with Achish, the Philistine officers said, "Send this man back to where he came from. Let him stick to his normal duties. He's not going into battle with us. He'd switch sides in the middle of the fight! What better chance to get back in favor with his master than by stabbing us in the back! 5 Isn't this the same David they celebrate at their parties, singing, Saul kills by the thousand, David by the ten thousand!"
6 So Achish had to send for David and tell him, "As God lives, you've been a trusty ally - excellent in all the ways you have worked with me, beyond reproach in the ways you have conducted yourself. But the warlords don't see it that way. 7 So it's best that you leave peacefully, now. It's not worth it, displeasing the Philistine warlords." 8 "But what have I done?" said David. "Have you had a single cause for complaint from the day I joined up with you until now? Why can't I fight against the enemies of my master the king?" 9 "I agree," said Achish. "You're a good man - as far as I'm concerned, God's angel! But the Philistine officers were emphatic: 'He's not to go with us into battle.' 10 So get an early start, you and the men who came with you. As soon as you have light enough to travel, go." 11 David rose early, he and his men, and by daybreak they were on their way back to Philistine country. The Philistines went on to Jezreel.

Commentary on 1 Samuel 29:1-5
(Read 1 Samuel 29:1-5)
David waited with a secret hope that the Lord would help him out of his difficulty. But he seems to have been influenced too much by the fear of man, in consenting to attend Achish. It is hard to come near to the brink of sin, and not to fall in. God inclined the princes of the Philistines to oppose David's being employed in the battle. Thus their dislike befriended him, when no friend could do him such a kindness.
Commentary on 1 Samuel 29:6-11
(Read 1 Samuel 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.
