So the children of Benjamin saw that they were struck; for the men of Israel gave place to Benjamin, because they trusted to the liers-in-wait whom they had set against Gibeah.
All of the men of Benjamin except that six hundred were destroyed.  Not only that, the last verses of the chapter indicate that all of the cities of Benjamin, being then without protection, were put to the sword, men, women and children without mercy.  There were not even any women left to marry the remaining six hundred Benjamites, because in their anger, the children of Israel had bound themselves with an oath never to give their daughters in marriage to the sons of Benjamin.
