1 Samuel 26:9-11

But David said to Abishai, “Do not destroy him, for who can put out his hand against the LORD’s anointed and be guiltless?” And David said, “As the LORD lives, the LORD will strike him, or his day will come to die, or he will go down into battle and perish. The LORD forbid that I should put out my hand against the LORD’s anointed. But take now the spear that is at his head and the jar of water, and let us go.”
