1 Samuel 24:17 (KJV)

The LORD judge between me and thee, and the LORD avenge me of thee: but mine hand shall not be upon thee.

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.

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 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.

For if a man find his enemy, will he let him go well away? wherefore the LORD reward thee good for that thou hast done unto me this day.

And now, behold, I know well that thou shalt surely be king, and that the kingdom of Israel shall be established in thine hand.

Swear now therefore unto me by the LORD, that thou wilt not cut off my seed after me, and that thou wilt not destroy my name out of my father's house.

And David sware unto Saul. And Saul went home; but David and his men gat them up unto the hold.
