1 Samuel 24:16 (KJV)

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

The Lord therefore be judge, and judge between me and thee, and see, and plead my cause, and deliver me out of thine hand.

And it came to pass, when David had made an end of speaking these words unto Saul, that Saul said, Is this thy voice, my son David? And Saul lifted up his voice, and wept.

And he said to David, Thou art more righteous than I: for thou hast rewarded me good, whereas I have rewarded thee evil.

And thou hast shewed this day how that thou hast dealt well with me: forasmuch as when the Lord had delivered me into thine hand, thou killedst me not.
