1 Samuel 26:11-12

11But may the Lord prevent me from extending my hand against the Lord’s chosen one! Now take the spear by Saul’s head and the jug of water, and let’s get out of here!”

12So David took the spear and the jug of water by Saul’s head, and they got out of there. No one saw them or was aware of their presence or woke up. All of them were asleep, for the Lord had caused a deep sleep to fall on them.
