Athaliah
2 Chronicles 22:2-4
2
Forty and two years old was Ahaziah when he began to reign, and he reigned one year in Jerusalem. His mother's name also was Athaliah the daughter of Omri.
3
He also walked in the ways of the house of Ahab: for his mother was his counsellor to do wickedly.
4
Wherefore he did evil in the sight of the LORD like the house of Ahab: for they were his counsellors after the death of his father to his destruction.
2 Kings 11:1
And when Athaliah the mother of Ahaziah saw that her son was dead, she arose and destroyed all the seed royal.
