The book of Jeremiah is Prophetic Oracle and Narrative History, although not completely in chronological order. The prophet Jeremiah wrote it sometime during his ministry about 626-586 B. C. Key personalities are the many kings Judah, Baruch, Ebdemelech, King Nebuchadnezzar, and the Rechabites. Its purpose was to warn of the destruction that they were about to face and to urge Judah to return and submit to God.
