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 Ierusalem made Ahaziah his yongest sonne King in his steade: for the armie that came with the Arabians to the campe, had slayne all the eldest: therefore Ahaziah the sonne of Iehoram King of Iudah reigned. 2 Two and fourtie yeere olde was Ahaziah when he began to reigne, and he reigned one yeere in Ierusalem. and his mothers name was Athaliah the daughter of Omri. 3 He walked also in the wayes of the house of Ahab: for his mother counselled him to doe wickedly. 4 Wherefore he did euill in the sight of the Lord, like the house of Ahab: for they were his counsellers after the death of his father, to his destruction. 5 And he walked after their counsel, and went with Iehoram the sonne of Ahab King of Israel to fight against Hazael king of Aram at Ramoth Gilead: and the Aramites smote Ioram. 6 And he returned to be healed in Izreel, because of the woundes wherewith they had wounded him at Ramah, when he fought with Hazael King of Aram. Nowe Azariah the sonne of Iehoram King of Iudah went downe to see Iehoram the sonne of Ahab at Izreel, because hee was diseased. 7 And the destruction of Ahaziah came of God in that he went to Ioram: for when he was come, he went forth with Iehoram against Iehu the sonne of Nimshi, whom the Lord had anointed to destroy the house of Ahab. 8 Therefore when Iehu executed iudgement vpon the house of Ahab, and found the princes of Iudah and the sonnes of the brethren of Ahaziah that waited on Ahaziah, he slew them also. 9 And he sought Ahaziah, and they caught him where he was hid in Samaria, and brought him to Iehu, and slewe him, and buryed him, because, sayd they, he is the sonne of Iehoshaphat, which sought the Lord with all his heart. So the house of Ahaziah was not able to reteine the kingdome. 10 Therefore when Athaliah the mother of Ahaziah sawe that her sonne was dead, shee arose and destroyed all the Kings seede of the house of Iudah. 11 But Iehoshabeath the daughter of ye King, tooke Ioash the sonne of Ahaziah, and stale him from among the Kings sonnes, that shoulde be slayne, and put him and his nource in the bed chamber: so Iehoshabeath the daughter of King Iehoram the wife of Iehoiada the Priest (for shee was the sister of Ahaziah) hid him from Athaliah: so she slew him not. 12 And hee was with them hid in the house of God sixe yeeres, whiles Athaliah reigned ouer the land.
