I Samuel 26:9-17, 24

But David said to Abishai, “Do not destroy him; for who can stretch out his hand against the LORD’s anointed, and be guiltless?” David said furthermore, “As the LORD lives, the LORD shall strike him, or his day shall come to die, or he shall go out to battle and perish. The LORD forbid that I should stretch out my hand against the LORD’s anointed. But please, take now the spear and the jug of water that are by his head, and let us go.” So David took the spear and the jug of water by Saul’s head, and they got away; and no man saw or knew it or awoke. For they were all asleep, because a deep sleep from the LORD had fallen on them. Now David went over to the other side, and stood on the top of a hill afar off, a great distance being between them. And David called out to the people and to Abner the son of Ner, saying, “Do you not answer, Abner?” Then Abner answered and said, “Who are you, calling out to the king?” So David said to Abner, “Are you not a man? And who is like you in Israel? Why then have you not guarded your lord the king? For one of the people came in to destroy your lord the king. This thing that you have done is not good. As the LORD lives, you deserve to die, because you have not guarded your master, the LORD’s anointed. And now see where the king’s spear is, and the jug of water that was by his head.” Then Saul knew David’s voice, and said, “Is that your voice, my son David?” David said, “It is my voice, my lord, O king.”

And indeed, as your life was valued much this day in my eyes, so let my life be valued much in the eyes of the LORD, and let Him deliver me out of all tribulation.”
