Judges 20:26-28

26Then all the Israelites, the whole army, went up to Bethel, and there they sat weeping before the Lord. They fasted that day until evening and presented burnt offerings and fellowship offerings to the Lord. 27And the Israelites inquired of the Lord. (In those days the ark of the covenant of God was there, 28with Phinehas son of Eleazar, the son of Aaron, ministering before it.) They asked, “Shall we go up again to fight against the Benjamites, our fellow Israelites, or not?” The Lord responded, “Go, for tomorrow I will give them into your hands.”
