1 Samuel 26:9-11

9 And David said to Abishai, Do not destroy him, for who has stretched forth his hand against the LORD'S anointed, and remained innocent?

10 David said furthermore, [As] the LORD lives, if the LORD does not smite him or his day comes to die or he descends into battle and perishes,

11 the LORD forbid that I should stretch forth my hand against the LORD'S anointed; but, I pray thee, take thou now the spear that [is] at his head and the cruse of water and let us go.
