1 Samuel 26:7-12

7So David and Abishai came to the people by night, and behold, Saul lay sleeping inside the circle of the camp with his spear stuck in the ground at his head; and Abner and the people were lying around him. 8Then Abishai said to David, “Today God has handed your enemy over to you; now then, please let me 1pin him with the spear to the ground with one thrust, and I will not 2do it to him a second time.” 9But David said to Abishai, “Do not 3kill him, for 4who can reach out with his hand against the Lord’s anointed and remain innocent?” 10David also said, “As the Lord lives, 5the Lord certainly will strike him, or 6his day will come that he dies, or 7he will go down in battle and 8perish. 119The Lord forbid that I would reach out with my hand against the Lord’s anointed! But now please take the spear that is at his head and the jug of water, and let’s go.” 12So David took the spear and the jug of water that were at Saul’s head, and they left; and no one saw or knew about it, nor did anyone awaken, for they were all asleep, because 10a deep sleep from the Lord had fallen on them.
