1 Samuel 29:9-11

American Standard Version

⁹ And Achish answered and said to David, I know that thou art good in my sight, as an angel of God: notwithstanding the princes of the Philistines have said, He shall not go up with us to the battle. ¹⁰ Wherefore now rise up early in the morning with the servants of thy lord that are come with thee; and as soon as ye are up early in the morning, and have light, depart. ¹¹ So David rose up early, he and his men, to depart in the morning, to return into the land of the Philistines. And the Philistines went up to Jezreel.
