1 Samuel 26:9-11

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.”
