Judges 20:26-28

26So all the Israelites, the whole army, went up to Bethel. They wept and sat there before the Lord; they did not eat anything that day until evening. They offered up burnt sacrifices and tokens of peace to the Lord.

27The Israelites asked the Lord (for the ark of God’s covenant was there in those days;

28Phinehas son of Eleazar, son of Aaron, was serving the Lord in those days), “Should we once more march out to fight the Benjaminites our brothers, or should we quit?” The Lord said, “Attack, for tomorrow I will hand them over to you.”
