1 Samuel 26:11-12

11But the LORD forbid that I should lay a hand on the LORD ’s anointed. Now get the spear and water jug that are near his head, and let’s go.”

12So David took the spear and water jug near Saul’s head, and they left. No one saw or knew about it, nor did anyone wake up. They were all sleeping, because the LORD had put them into a deep sleep.
