1 Samuel 11:13

And Saul said, There shall not a man be put to death this day; for today the Lord hath wrought salvation in Israel. This was not only tactful and magnanimous, but showed true piety of heart, which would not permit the sacred joy of the day of victory to be marred by bloodshed, since the victory of the foe was for him nothing but a saving act of God Himself. It was an utterance of royal generosity toward his personal enemies, whose hearts he wanted to win; it was a victory over himself.
