1 Samuel 26:13

9 But David said to Abishai, “Do not destroy him, for who can lift a hand against the LORD’s anointed and be guiltless?”

10 David added, “As surely as the LORD lives, the LORD Himself will strike him down; either his day will come and he will die, or he will go into battle and perish.

11 But the LORD forbid that I should stretch out my hand against the LORD’s anointed. Instead, take the spear and water jug by his head, and let us go.”

12 So David took the spear and water jug by Saul’s head, and they departed. No one saw them or knew about it, nor did anyone wake up; they all remained asleep, because a deep sleep from the LORD had fallen on them.

13 Then David crossed to the other side and stood atop the mountain at a distance; there was a wide gulf between them.

14 And David shouted to the troops and to Abner son of Ner, “Will you not answer me, Abner?” “Who calls to the king?” Abner replied.

15 So David said to Abner, “You are a man, aren’t you? And who in Israel is your equal? Why then did you not protect your lord the king when one of the people came to destroy him?

16 This thing you have done is not good. As surely as the LORD lives, all of you deserve to die, since you did not protect your lord, the LORD’s anointed. Now look around. Where are the king’s spear and water jug that were by his head?”

17 Then Saul recognized David’s voice and asked, “Is that your voice, David my son?” “It is my voice, my lord and king,” David said.
