“Judas made war on the descendents of Esau in Idumea, at Akrabattene, because they kept lying in wait for Israel. He dealt them a heavy blow. He humbled them and despoiled them. He also remembered the wickedness of the sons of Baean, who were a trap and a snare to the people as they ambushed them on the highways. They were shut up by him in their towers. He encamped against them. He vowed their complete destruction. He burned with fire their towers and all who were in them.”
The descendents of Esau are not exactly gentiles since Esau was the brother of Jacob. In fact they were all Semites, not gentiles, since they were all related. Nevertheless, Judas Maccabeus attacked them in Idumea in Akrabattene, which was on the border of Judea and Idumea, south of Judea. They were wicked people who would attack people on the highways like highway robbers. He burned them in their towers.
