1 Samuel 26:9

But David said to Abishai, “Don’t you dare hurt him! Who could lay a hand on God’s anointed and even think of getting away with it?”

^10-11 He went on, “As God lives, either God will strike him, or his time will come and he’ll die in bed, or he’ll fall in battle, but God forbid that I should lay a finger on God’s anointed. Now, grab the spear at his head and the water jug and let’s get out of here.”
