Judges 20:27-28

And the children of Israel made request to the Lord, (for the ark of the agreement of the Lord was there in those days, And Phinehas, the son of Eleazar, the son of Aaron, was in his place before it,) and said, Am I still to go on with the fight against the children of Benjamin my brother, or am I to give it up? And the Lord said, Go on; for tomorrow I will give him into your hands.
