1 Samuel 29:6-11

6So Achish summoned David and said to him, “As surely as the Lord lives, you are an honest man, and I am glad to have you serving with me in the army. I have found no fault with you from the day that you first came to me until the present time. But in the opinion of the leaders, you are not reliable.

7So turn and leave in peace. You must not do anything that the leaders of the Philistines consider improper!”

8But David said to Achish, “What have I done? What have you found in your servant from the day that I first came into your presence until the present time, that I shouldn’t go and fight the enemies of my lord the king?”

9Achish replied to David, “I am convinced that you are as reliable as the angel of God! However, the leaders of the Philistines have said, ‘He must not go up with us in the battle.’

10So get up early in the morning along with the servants of your lord who have come with you. When you get up early in the morning, as soon as it is light enough to see, leave.”

11So David and his men got up early in the morning to return to the land of the Philistines, but the Philistines went up to Jezreel.
