Judges 21:5-8

5Then the Israelites asked, “Who from all the tribes of Israel has failed to assemble before the Lord?” For they had taken a solemn oath that anyone who failed to assemble before the Lord at Mizpah was to be put to death.

6Now the Israelites grieved for the tribe of Benjamin, their fellow Israelites. “Today one tribe is cut off from Israel,” they said.

7“How can we provide wives for those who are left, since we have taken an oath by the Lord not to give them any of our daughters in marriage?”

8Then they asked, “Which one of the tribes of Israel failed to assemble before the Lord at Mizpah?” They discovered that no one from Jabesh Gilead had come to the camp for the assembly.
