1 Samuel 11:13

And Saul said, There shall not a man be put to death this day. — A wise, as well as a generous, decision; anything like a bloody vengeance would have been the commencement of future feuds and bitter heart-burnings between the new king and the powerful families of the other tribes, who misliked and opposed his election. Saul began his reign with wise discretion, as well as with heroic valour. By this determined refusal to avenge the cruel affront showed to him, he taught “kings to be” how truly a royal virtue was forgiveness of all past wrongs.

For to day the Lord hath wrought salvation in Israel. — And as yet unspoiled, the king’s heart was full of humble reverent piety. By this first public act of pardon, he “not only signified that the public rejoicing should not be interrupted, but reminded them of the clemency of God, and urged that since Jehovah had shown such clemency upon that day, that He overlooked their sins, and had given them a glorious victory. it was only right they should follow His example, and forgive their neighbours’ sins without bloodshed.” (Seb. Schmidt, quoted by Keil and Delitsch.)
