1 Samuel 29:9-11

9“I know,” Achish answered saying to David. “You are as pleasing in my eyes as an angel of God. Nevertheless, the Philistine commanders have said, ‘He must not go up with us to the battle.’

10So now, rise up early in the morning, you and the servants of your lord that came with you, and as soon you rise, early in the morning, once there is light, leave.”

11So David rose up early, he and his men, leaving in the morning to return to the land of the Philistines. Meanwhile, the Philistines went up to Jezreel.
