1 Samuel 26:9-17

9But David said to Abishai, “Do not destroy him, for who can put out his hand against the LORD’s anointed and be guiltless?” 10And David said, “As the LORD lives, the LORD will strike him, or his day will come to die, or he will go down into battle and perish. 11The LORD forbid that I should put out my hand against the LORD’s anointed. But take now the spear that is at his head and the jar of water, and let us go.” 12So David took the spear and the jar of water from Saul’s head, and they went away. No man saw it or knew it, nor did any awake, for they were all asleep, because a deep sleep from the LORD had fallen upon them. 13Then David went over to the other side and stood far off on the top of the hill, with a great space between them. 14And David called to the army, and to Abner the son of Ner, saying, “Will you not answer, Abner?” Then Abner answered, “Who are you who calls to the king?” 15And David said to Abner, “Are you not a man? Who is like you in Israel? Why then have you not kept watch over your lord the king? For one of the people came in to destroy the king your lord. 16This thing that you have done is not good. As the LORD lives, you deserve to die, because you have not kept watch over your lord, the LORD’s anointed. And now see where the king’s spear is and the jar of water that was at his head.” 17Saul recognized David’s voice and said, “Is this your voice, my son David?” And David said, “It is my voice, my lord, O king.”
