1 Samuel 29:6-11

6So Achish called David and said to him, “As surely as the Lord lives, you have been reliable, and I would be pleased to have you serve with me in the army. From the day you came to me until today, I have found no fault in you, but the rulers don’t approve of you. 7Now turn back and go in peace; do nothing to displease the Philistine rulers.” 8“But what have I done?” asked David. “What have you found against your servant from the day I came to you until now? Why can’t I go and fight against the enemies of my lord the king?” 9Achish answered, “I know that you have been as pleasing in my eyes as an angel of God; nevertheless, the Philistine commanders have said, ‘He must not go up with us into battle.’ 10Now get up early, along with your master’s servants who have come with you, and leave in the morning as soon as it is light.” 11So David and his men got up early in the morning to go back to the land of the Philistines, and the Philistines went up to Jezreel.
