Judges 21:2-4

2And the people came to Bethel, and abode there till even before 1God, and lifted up their voices and wept bitterly,

3and said, Jehovah, 2God of Israel, why is it come to pass in Israel, that there should be this day one tribe lacking in Israel?

4And it came to pass on the morrow, that the people rose early, and built there an altar, and offered up burnt-offerings and peace-offerings.
