1 Samuel 26:9-11

9But David said to Abishai, “Do not kill him, for who can put out his hand against the Lord’s anointed [king] and be guiltless (innocent)?”

10David also said, “As the Lord lives, most certainly the Lord will strike him [in His own time and way], or his day will come and he will die, or he will go down into battle and be carried off [dead].

11The Lord forbid that I would put out my hand against the Lord’s anointed; but now take the spear that is by his head and the jug of water, and let us go.”
