Judges 21:4-7 The Message (MSG)
4 Early the next morning, the people got busy and built an altar. They sacrificed Whole-Burnt-Offerings and Peace-Offerings.
5 Then the Israelites said, “Who from all the tribes of Israel didn’t show up as we gathered in the presence of God?” For they had all taken a sacred oath that anyone who had not gathered in the presence of God at Mizpah had to be put to death.
6-7 But the People of Israel were feeling sorry for Benjamin, their brothers. They said, “Today, one tribe is cut off from Israel. How can we get wives for those who are left? We have sworn by God not to give any of our daughters to them in marriage.”
