1 Samuel 26:9-11

9 David said to Abishai, Don't destroy him; for who can put forth his hand against Yahweh's anointed, and be guiltless?  10 David said, As Yahweh lives, Yahweh will strike him; or his day shall come to die; or he shall go down into battle and perish.  11 Yahweh forbid that I should put forth my hand against Yahweh's anointed: but now please take the spear that is at his head, and the jar of water, and let us go.
