King Ahaziah of Judah
(2 Kings 8.25-292 9.212 272 28)1 Earlier, when the Arabs led a raid against Judah, they killed all of Jehoram's sons, except Ahaziah, the youngest one. So the people of Jerusalem crowned him their king. 2 He was 22 years old at the time, and he ruled only one year from Jerusalem.
Ahaziah's mother was Athaliah, a granddaughter of King Omri of Israel, 3 and she encouraged her son to sin against the Lord. He followed the evil example of King Ahab and his descendants. 4 In fact, after his father's death, Ahaziah sinned against the Lord by appointing some of Ahab's relatives to be his advisors.
Their advice led to his downfall. 5 He listened to them and went with King Joram of Israel to attack King Hazael and the Syrian troops at Ramoth in Gilead. Joram was wounded in that battle, 6 and he went to the town of Jezreel to recover. And Ahaziah later went there to visit him. 7 It was during that visit that God had Ahaziah put to death.
When Ahaziah arrived at Jezreel, he and Joram went to meet with Jehu grandson of Nimshi. The Lord had already told Jehu to kill every male in Ahab's family, 8 and while Jehu was doing that, he saw some of Judah's leaders and Ahaziah's nephews who had come with Ahaziah. Jehu killed them on the spot, 9 then gave orders to find Ahaziah. Jehu's officers found him hiding in Samaria. They brought Ahaziah to Jehu, who immediately put him to death. They buried Ahaziah only because they respected Jehoshaphat his grandfather, who had done his best to obey the Lord.
There was no one from Ahaziah's family left to become king of Judah.
Queen Athaliah of Judah
(2 Kings 11.1-3)10 As soon as Athaliah heard that her son King Ahaziah was dead, she decided to kill any relative who could possibly become king. She would have done just that, 11 but Jehosheba rescued Joash son of Ahaziah just as the others were about to be murdered. Jehosheba, who was Jehoram's daughter and Ahaziah's half sister, was married to Jehoiada the priest. So she was able to hide her nephew Joash and his personal servant in a bedroom in the Lord's temple where he was safe from Athaliah. 12 Joash hid in the temple with them for six years while Athaliah ruled as queen 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 eldest. 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 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.
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 smote 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 destruction of Ahaziah was of God by coming to Joram: for when he was 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 brethren of Ahaziah, that ministered to Ahaziah, he slew them. 9 And he sought Ahaziah: and they caught him, (for he was hid in Samaria,) and brought him to Jehu: and when they had slain him, they buried him: Because, said they, he is the son of Jehoshaphat, who sought the LORD with all his heart. So the house of Ahaziah had no power to keep still the kingdom.
10 ¶ But when Athaliah the mother of Ahaziah saw that her son was dead, she arose and destroyed all the seed royal of the house of Judah. 11 But Jehoshabeath, the daughter of the king, took Joash the son of Ahaziah, and stole him from among the king’s sons that were 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 with them hid in the house of God six years: and Athaliah reigned over the land.
