"another Jehu, a Cyrus, or a Nebuchadnezzar"
These figures were all responsible for cleansing Jerusalem of unbelievers. Jehu
was a king of Israel who killed Jezebel
and the worshippers of Baal (meaning spirit-deities and hence, in Christianity, false gods). Cyrus
, the Persian king charged by God with building a temple in Jerusalem, established his kingdom mainly through conquest. Nebuchadnezzar
was a king of Babylon who, in alliance with the Medes
, overthrew the Assyrian Empire and destroyed Ninevah.
