1 Samuel 24:10-13

10Behold, this day thy eyes have seen how the LORD hath delivered thee to day into my hand in the cave: and some bade me kill thee: but my eye spared thee; and I said, I will not put forth my hand against my lord; for he is the LORD’S anointed. 11Moreover, my father, see, yea, see the skirt of thy robe in my hand: for in that I cut off the skirt of thy robe, and killed thee not, know thou and see that there is neither evil nor transgression in my hand, and I have not sinned against thee; yet thou huntest my soul to take it. 12The LORD judge between me and thee, and the LORD avenge me of thee: but my hand shall not be upon thee. 13As saith the proverb of the ancients, Wickedness proceedeth from the wicked: but my hand shall not be upon thee.
