1 Samuel 26:9-11

9But David said to Abishai, “Don’t kill him! Who can extend his hand against the Lord’s chosen one and remain guiltless?”

10David went on to say, “As the Lord lives, the Lord himself will strike him down. Either his day will come and he will die, or he will go down into battle and be swept away.

11But may the Lord prevent me from extending my hand against the Lord’s chosen one! Now take the spear by Saul’s head and the jug of water, and let’s get out of here!”
