The Animal Apocalypse within 1 Enoch (chapters 85–90), is another example where conflict sparks hopes for the New Jerusalem. First Enoch is an apocalyptic response to the persecutions under Seleucid Emperor Antiochus IV. In 167 BCE, Emperor Antiochus returned from fighting in Egypt to quell a revolt in Jerusalem led by Jason, the former High Priest. An agitated Antiochus imposed harsh restrictions on Jewish religion. Circumcision, feast celebration, Sabbath observance were all banned. Antiochus ordered the burning of Torah copies. Jews were required to eat pork. The worst oppression came in the desecration of the Temple. A polytheistic cult was formed, and worship of YHWH abolished. A statue to a Seleucid deity was constructed on the Jewish altar.
