1 Samuel 26:8-11

8Then Abishai said to David, “Today God has delivered your enemy to you. Let me thrust the spear through him into the ground just once. I won’t have to strike him twice!”

9But David said to Abishai, “Don’t destroy him, for who can lift a hand against the Lord’s anointed and be innocent?”

10David added, “As the Lord lives, the Lord will certainly strike him down: either his day will come and he will die, or he will go into battle and perish.

11However, as the Lord is my witness, I will never lift my hand against the Lord’s anointed. Instead, take the spear and the water jug by his head, and let’s go.”
