“Apollonius now gathered together gentiles and a large force from Samaria to fight against Israel. When Judas learned of it, he went out to meet him. He defeated and killed him. Many were wounded and fell. The rest fled. Then they seized their spoils. Judas took the sword of Apollonius. He used it in battle the rest of his life.”
Apparently this Apollonius was the governor of Samaria. He gathered a group of gentiles in Samaria, which normally did not like Judea anyway. Judas Maccabeus then out to battle, defeated, and killed him. He seized the spoils of the group around Apollonius including his sword, which he seems to like so much that he used in future battles.
