Adam Clarke on Judges 21:8

There came none to the camp from Jabesh-gilead - As they had sworn to destroy those who would not assist in this war, Jdg 21:5, they determined to destroy the men of Jabesh, and to leave none alive except the virgins, and to give these to the six hundred Benjamites that had escaped to the rock Rimmon. So twelve thousand men went, smote the city, and killed all the males and all the married women. The whole account is dreadful; and none could have been guilty of all these enormities but those who were abandoned of God. The crime of the men of Gibeah was of the deepest die; the punishment, involving both the guilty and innocent, was extended to the most criminal excess; and their mode or redressing the evil which they had occasioned was equally abominable.
