Judges 21:1-7 King James Version (KJV)
21 Now the men of Israel had sworn in Mizpeh, saying, There shall not any of us give his daughter unto Benjamin to wife.
2 And the people came to the house of God, and abode there till even before God, and lifted up their voices, and wept sore;
3 And said, O Lord God of Israel, why is this come to pass in Israel, that there should be to 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 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 unto the Lord? For they had made a great oath concerning him that came not up to the Lord to Mizpeh, saying, He shall surely be put to death.
6 And the children of Israel repented them for Benjamin their brother, and said, There is one tribe cut off from Israel this day.
7 How shall we do for wives for them that remain, seeing we have sworn by the Lord that we will not give them of our daughters to wives?
