Judges 20:26-28

26Then the Israelites, all the people, went up to Bethel, where they sat weeping before the LORD. That day they fasted until evening and presented burnt offerings and peace offerings to the LORD. 27And the Israelites inquired of the LORD. (In those days the ark of the covenant of God was there, 28and Phinehas son of Eleazar, the son of Aaron, served before it.) The Israelites asked, “Should we again go out to battle against our brothers the Benjamites, or should we stop?”

The LORD answered, “Fight, for tomorrow I will deliver them into your hand.”
