1 Samuel 24:12 KJV

10Behold, this day thine eyes have seen how that the LORD had delivered thee to day into mine hand in the cave: and some bade me kill thee: but mine eye spared thee; and I said, I will not put forth mine 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 mine 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 mine hand shall not be upon thee.

13As saith the proverb of the ancients, Wickedness proceedeth from the wicked: but mine hand shall not be upon thee.

14After whom is the king of Israel come out? after whom dost thou pursue? after a dead dog, after a flea.
