Judges 21:8-10

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.

9For when they counted the people, they found that none of the people of Jabesh Gilead were there.

10So the assembly sent twelve thousand fighting men with instructions to go to Jabesh Gilead and put to the sword those living there, including the women and children.
