1 Samuel 24:12

Behold, 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.

Moreover, 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.

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

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