Judges 21:3-5

Darby Translation

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

⁴ And 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.

⁵ And the children of Israel said, Who is there among all the tribes of Israel that came not up with the congregation to Jehovah? For they had [made] a great oath concerning him that came not up to Jehovah to Mizpah, saying, He shall certainly be put to death.
