1 Samuel 12:12

And when ye saw that Nahash, the king of the children of Ammon, came against you, who thus had evidently made several raids against the territory of Israel before his bolder campaign against Jabesh, ye said unto me, Nay; but a king shall reign over us; when the Lord, your God, was your king, who had, by awaking Judges and saviors, always delivered them out of the hands of their enemies. So their demand for a king had really been a bit of foolish caprice, of sinful rejection of the Lord.
