1 Samuel 26:5-14

5Then David rose and came to the place where Saul had encamped. And David saw the place where Saul lay, with Abner the son of Ner, the commander of his army. Saul was lying within the encampment, while the army was encamped around him.

6Then David said to Ahimelech the Hittite, and to Joab's brother Abishai the son of Zeruiah, "Who will go down with me into the camp to Saul?" And Abishai said, "I will go down with you."

7So David and Abishai went to the army by night. And there lay Saul sleeping within the encampment, with his spear stuck in the ground at his head, and Abner and the army lay around him.

8Then Abishai said to David, "God has given your enemy into your hand this day. Now please let me pin him to the earth with one stroke of the spear, and I will not strike him twice."

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?"
