1 Samuel 29:6-11

6And Achish called David, and said to him, [As] Jehovah liveth, thou art upright, and thy going out and thy coming in with me in the camp is acceptable to me; for I have not found evil in thee since the day of thy coming to me to this day; but thou art not acceptable to the lords. 7And now return, and go in peace, that thou displease not the lords of the Philistines. 8And David said to Achish, But what have I done? and what hast thou found in thy servant so long as I have been with thee to this day, that I should not go and fight against the enemies of my lord the king? 9And Achish answered and said to David, I know that thou art acceptable to me, as an angel of 1God; nevertheless the princes of the Philistines have said, He shall not go up with us to the battle. 10And now rise up early in the morning with thy master's servants that are come with thee; and rise ye early in the morning, and when ye have daylight, depart. 11And David rose up early, he and his men, to depart in the morning, to return into the land of the Philistines. And the Philistines went up to Jizreel.
