1 Samuel 29:9-11

9Achish answered David, “I’m convinced that you are as reliable as an angel of God. But the Philistine commanders have said, ‘He must not go into battle with us.’

10So get up early in the morning, you and your masters’ servants who came with you. When you’ve all gotten up early, go as soon as it’s light.”

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