1 Samuel 26:5-11

5Then David set out and went to the place where Saul had camped. He saw where Saul and Abner son of Ner, the commander of the army, had lain down. Saul was lying inside the camp, with the army encamped around him.

6David then asked Ahimelek the Hittite and Abishai son of Zeruiah, Joab’s brother, “Who will go down into the camp with me to Saul?” “I’ll go with you,” said Abishai.

7So David and Abishai went to the army by night, and there was Saul, lying asleep inside the camp with his spear stuck in the ground near his head. Abner and the soldiers were lying around him.

8Abishai said to David, “Today God has delivered your enemy into your hands. Now let me pin him to the ground with one thrust of the spear; I won’t strike him twice.” 9But David said to Abishai, “Don’t destroy him! Who can lay a hand on the LORD ’s anointed and be guiltless? 10As surely as the LORD lives,” he said, “the LORD himself will strike him, or his time will come and he will die, or he will go into battle and perish.

11But the LORD forbid that I should lay a hand on the LORD ’s anointed. Now get the spear and water jug that are near his head, and let’s go.”
