1 Samuel 29:6-11

6So Achish finally summoned David and said to him, “I swear by the Lord that you have been a trustworthy ally. I think you should go with me into battle, for I’ve never found a single flaw in you from the day you arrived until today. But the other Philistine rulers won’t hear of it.

7Please don’t upset them, but go back quietly.”

8“What have I done to deserve this treatment?” David demanded. “What have you ever found in your servant, that I can’t go and fight the enemies of my lord the king?”

9But Achish insisted, “As far as I’m concerned, you’re as perfect as an angel of God. But the Philistine commanders are afraid to have you with them in the battle.

10Now get up early in the morning, and leave with your men as soon as it gets light.”

11So David and his men headed back into the land of the Philistines, while the Philistine army went on to Jezreel.
