7
God brought about Ahaziah's downfall when he went to Joram. He went with Joram to meet Jehu, grandson of Nimshi. (The LORD had anointed Jehu to destroy Ahab's family.)
8
When Jehu was executing judgment on Ahab's family, he found Judah's leaders (Ahaziah's nephews) who were serving Ahaziah, and he killed them.
9
He searched for Ahaziah, and Jehu's men captured him while he was hiding in Samaria. They brought him to Jehu and killed him. Then they buried him. They explained, "Ahaziah is Jehoshaphat's grandson. Jehoshaphat dedicated his life to serving the LORD with all his heart." But no one in Ahaziah's family was able to rule as king.
10
When Ahaziah's mother, Athaliah, saw that her son was dead, she began to destroy the entire royal family of the house of Judah.
11
But Jehoshebath, daughter of the king and sister of Ahaziah, took Ahaziah's son Joash. She saved him from being killed with the king's other sons, and she put him and his nurse in a bedroom. Jehoshebath was the daughter of King Jehoram and wife of Jehoiada the priest. Because she was also Ahaziah's sister, she hid Joash from Athaliah. So he wasn't killed.
12
Joash was with the priests. He was hidden in God's temple for six years while Athaliah ruled the country.
