Ahaziah King of Judah
1     And the inhabitants of Jerusalem made Ahaziah his youngest son king in his stead: for the band of men that came with the Arabians to the  camp  had  slain  all  the  older  sons.  So Ahaziah the son of Jehoram king of Judah reigned.
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 granddaughter of Omri.
3    He also walked in the ways of the house of Ahab: for his  mother was his counselor to do wickedly.
4     Therefore he did evil in the sight of the LORD like the house of Ahab: for they were his counselors after the death of his father, to his destruction.
5   He walked also after their counsel, and went with Jehoram the son of Ahab king of Israel to war against Hazael king of Syria at Ramoth- gilead: and the Syrians wounded Joram.
6     And he returned to be healed in Jezreel because of the wounds which were given him at Ramah,  when  he  fought  with  Hazael  king  of Syria. And Azariah the son of Jehoram king of Judah  went  down  to  see  Jehoram  the  son  of Ahab at Jezreel, because he was sick.
7    And the downfall of Ahaziah was of God by his coming to Joram: for when he had come, he went out with Jehoram against Jehu the son of Nimshi, whom the LORD had anointed to cut off the house of Ahab.
8    And it came to pass, that, when Jehu was executing judgment upon the house of Ahab, and found the princes of Judah, and the sons of the brothers of Ahaziah, that ministered to Ahaziah, he killed them.
9     And he sought Ahaziah: and they caught him, (for he had hid in Samaria,) and brought him to  Jehu:  and  when  they  had  slain  him,  they buried him: Because, they said, he is the son of Jehoshaphat, who sought the LORD with all his heart. So the house of Ahaziah had no one able to rule the kingdom.

Athaliah Reigns as Queen
10    But when Athaliah the mother of Ahaziah saw that her son was dead, she arose and destroyed all the royal descendants of the house of Judah.
11      But  Jehoshabeath,  the  daughter  of  the king, took Joash the son of Ahaziah, and stole him away from among the king’s sons that were being slain, and put him and his nurse in a bedchamber. So Jehoshabeath, the daughter of king Jehoram, the wife of Jehoiada the priest, (for she was the sister of Ahaziah,) hid him from Athaliah, so that she slew him not.
12    And he was hid with them in the house of God  six  years:  and  Athaliah  reigned  over  the land.
