Judges 21:1 Meaning and Commentary

Judges 21:1

Now the men of Israel had sworn in Mizpeh
Where they were there convened, before the war began; after they had heard the account the Levite gave of the affair, which brought them thither; and after they had sent messengers to Benjamin to deliver up the men of Gibeah, that had committed the wickedness; and after they perceived that Benjamin did not hearken to their demand, but prepared to make war with them; then, as they resolved on the destruction of Gibeah, and of all the cities that sent out men against them, even all the inhabitants of them, men, women, and children, entered into an oath, that they would use those men that remained as Heathens, and not intermarry with them, as follows:

saying, there shall not any of us give his daughter unto Benjamin to
wife;
seeing those that used the wife of the Levite in such a base manner, and those that protected and defended them, deserved to have no wives.

Judges 21:1 In-Context

1 Now the children of Israel swore in Massephath, saying, No man of us shall give his daughter to Benjamin for a wife.
2 And the people came to Baethel, and sat there until evening before God: and they lifted up their voice and wept with a great weeping;
3 and said, Wherefore, O Lord God of Israel, has this come to pass, that to-day one tribe should be counted from Israel?
4 And it came to pass on the morrow that the people rose up early, and built there an altar, and offered up whole-burnt-offerings and peace offerings.
5 And the children of Israel said, Who of all the tribes of Israel, went not up in the congregation to the Lord? for there was a great oath concerning those who went not up to the Lord to Massephath, saying, He shall surely be put to death.
