Judges 20:46-48
46 On that day twenty-five thousand Benjamite swordsmen fell, all of them valiant fighters.
47 But six hundred men turned and fled into the desert to the rock of Rimmon, where they stayed four months.
48 The men of Israel went back to Benjamin and put all the towns to the sword, including the animals and everything else they found. All the towns they came across they set on fire.
