1 Samuel 29:9-11

Achish 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.’ Now 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.” So 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.
