1 Samuel 26:13

9David said to Abishai, “Don’t destroy him, for who can stretch out his hand against the LORD’s anointed, and be guiltless?”

10David said, “As the LORD lives, the LORD will strike him; or his day shall come to die, or he shall go down into battle and perish.

11The LORD forbid that I should stretch out my hand against the LORD’s anointed; but now please take the spear that is at his head and the jar of water, and let’s 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 on them.

13Then David went over to the other side, and stood on the top of the mountain far away, a great space being between them;

14and David cried to the people, and to Abner the son of Ner, saying, “Don’t you answer, Abner?” Then Abner answered, “Who are you who calls to the king?”

15David said to Abner, “Aren’t you 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 your lord the king.

16This thing isn’t good that you have done. As the LORD lives, you are worthy to die, because you have not kept watch over your lord, the LORD’s anointed. 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?” David said, “It is my voice, my lord, O king.”
