Ahaziah of Judah in 2 Kings

Ahaziah of Judah

Not to be confused with the earlier Ahaziah of Israel, Ahaziah of Judah is also a wicked king. The son of one of Ahab's daughters, Athaliah (who is herself another creature of the abyss), Ahaziah is close allies with Joram of Israel, with whom he fights against King Hazael of Aram (another highly disreputable character). Nevertheless, Ahaziah gets killed along with Joram when God tells Jehu to rebel and kill all of Ahab's family members. His son, Joash of Judah, ends up being a really good king.
