Unholy Alliances, II Chronicles 21-22, OT S1:E239

When the monarchs of Judah adopt the treachery and faithless behaviors of the kings of Israel, watch out! Jehoram begins his reign by killing his brothers, men who were, "more righteous than he." Ahaziah, his son, reigns only a year before the wicked Queen Mother Athaliah ascends to the throne. So much evil, so little hope.
