1 Samuel 26:4-12

4David sent out spies, and he learned that Saul was definitely coming. 5David then set out and came to the place where Saul had camped. And David saw the place where Saul lay, and 1Abner the son of Ner, the commander of his army; and Saul was lying in the circle of the camp, and the people were camped around him.

6Then David said to Ahimelech 2the Hittite and to 3Abishai the son of Zeruiah, Joab’s brother, saying, “Who 4will go down with me to Saul in the camp?” And Abishai said, “I will go down with you.” 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 5pin him with the spear to the ground with one thrust, and I will not 6do it to him a second time.” 9But David said to Abishai, “Do not 7kill him, for 8who can reach out with his hand against the Lord’s anointed and remain innocent?” 10David also said, “As the Lord lives, 9the Lord certainly will strike him, or 10his day will come that he dies, or 11he will go down in battle and 12perish. 1113The 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 14a deep sleep from the Lord had fallen on them.
