Sometime later, King Jehoshaphat of Judah entered into a military alliance with King Ahaziah of Israel, acting wickedly by doing so.

He also agreed with King Ahaziah to build ships to sail toward Tarshish, which they built in Ezion-geber.

But Dodavahu's son Eliezer from Mareshah prophesied in opposition to Jehoshaphat, "Because you have entered into an alliance with Ahaziah, the LORD has destroyed your efforts." So the ships were destroyed and were never able to sail for Tarshish.

The residents of Jerusalem made Jehoram's son Ahaziah king in his place after the raiding party that had invaded the city with the Arabs had killed all of the older sons. That's how Jehoram's son Ahaziah became king of Judah.

Ahaziah was 22 years old when he became king, and he reigned for one year in Jerusalem. His mother was Athaliah, Omri's granddaughter.

so he returned to Jezreel to recover from the wounds that he had received at Ramah in the battle against King Hazael of Aram. King Ahaziah of Judah, Jehoram's son, went to visit Ahab's son Joram, because he was wounded.

God used Ahaziah's visit to Joram to destroy Ahaziah. As soon as he arrived, Ahaziah went out with Joram to attack Nimshi's son Jehu, whom the LORD had appointed to eliminate Ahab's dynasty.

And that's exactly what happened. While Jehu was punishing Ahab's dynasty, he located the princes of Judah and the sons of Ahaziah's brothers who were ministering to Ahaziah, and he put them to death.

Jehu also searched for Ahaziah, had him apprehended while Ahaziah was hiding out in Samaria, and had Ahaziah brought to him. Jehu had Ahaziah executed and buried. It was said of Jehu, "He is the son of Jehoshaphat, who sought the LORD with all of his heart." As a result, there was no one left in the household of Ahaziah strong enough to reign in the kingdom.

As soon as Ahaziah's mother Athaliah learned that her son had died, she set out to destroy the entire royal family of Judah.

However, the king's daughter Jehoshabeath took Ahaziah's son Joash away from the king's children who were about to be assassinated and hid him and his nurse in a bedroom. That's how King Jehoram's daughter Jehoshabeath, who was also the priest Jehoiada's wife and Ahaziah's sister, hid him from Athaliah. As a result, she was not able to kill him.

King Joash of Israel captured Joash's son King Amaziah of Judah, the grandson of Ahaziah, at Beth-shemesh and brought him back to Jerusalem, where he broke down 400 cubits of the wall of Jerusalem from the Ephraim Gate to the Corner Gate.
