This book is about the "exile" prophets, Ezekiel, Daniel, and Obadiah. That is, those prophets who lived under Babylonian captivity. Ezekiel was a priest and was among the Jewish exiles carried away to Babylon during the deportation of Judah after King Nebuchadnezzar's conquest. He was a man of formidable integrity and purpose, entirely devoted to the practices of Judaism. Like Daniel and the Apostle John, his prophecy follows the method of symbolism and vision. The Book of Daniel, like The Revelation in the New Testament, is called an apocalypse, which means "unveiling." The use of apocalypses were given to show the reality behind that which was apparent, and to indicate the eventual victory of righteousness upon the earth. Little is known about Obadiah. The theme of his book is the Doom of Edom- the nation descended from Esau.
