Judges 20:26

Then all the children of Israel, the soldiers, and all the people, the non-combatants that had come along with the army, went up, and came unto the house of God, apparently again to Bethel, and wept, and sat there before the Lord, and fasted that day until evening, in deep sorrow over their own sins, for they felt that these defeats were placed upon them in the nature of a chastisement, in order to teach them humility and trust in God alone, and offered burnt offerings and peace-offerings before the Lord, sacrifices intended to plead for God's merciful assistance.
