1 Samuel 24:19

For if a man find his enemy, will he let him go well away? It was a most unusual way of dealing with an enemy, to let him go scot-free when such a fine chance to dispose of him offered. Wherefore the Lord reward thee good for that thou hast done unto me this day. For the time being, Saul permitted the nobler sentiments to come into his heart, but there was no true conversion.
