Ahab and Zedekiah were two prophets in Babylon, sons of Kolaiah and Maaseiah respectively. Jeremiah condemned them for false prophecy in Yahweh’s name and for immoral conduct.
Jeremiah announced that Nebuchadnezzar would slay them and that the Judean captives would use their fate as a curse.
The king of Babylon roasted them in the fire, an event remembered in the curse recorded in Jeremiah 29.
