1 Samuel 29:6-11

6Then Achish called David and said to him, “As the Lord lives, you have been upright (righteous), and your behavior in the army is pleasing in my sight. For from the day you came to me to this day I have found no evil in you. Nevertheless, the [Philistine] lords do not approve of you.

7So return now and go in peace [to your place], so that you do not displease the Philistine lords.”

8David said to Achish, “But what have I done? What have you found in your servant from the day when I [first] came before you to this day, that I may not go and fight against the enemies of my lord the king?”

9Achish answered David, “I know that you are blameless in my sight, like an angel of God; nevertheless the commanders of the Philistines have said, ‘He must not go up with us to the battle.’

10So now, get up early in the morning with your master’s servants who have come with you, and as soon as you are up in the morning and have light, leave.”

11So David and his men got up early to leave in the morning, to return to the land of the Philistines. But the Philistines went up to Jezreel [to fight against Israel].
