Angry, Antiochus invaded Palestine and attacked Jerusalem, He tore down its walls and took over the temple. Previously he had allowed Jews to freely practice their religion. No more. He entered the temple and placed a statue of the Greek god Zeus in the holy of holies. He then stood before the alter and slaughtered a pig, took the blood from the pig, and rubbed it over everything in the Temple. Defiling it.
The Temple was taken over by him. Inside it, all forms of debauchery took place. Outside of it He banned all Jewish religious practices.
