There are two people named Ahaziah in the Bible, and both were kings. One was king of the northern kingdom of Israel and the other was king of the southern kingdom of Judah. Both profiles are included below:
Ahaziah, King of Israel, was the uncle of Ahaziah, King of Judah. Israel's Ahaziah was the eighth king of the northern kingdom of Israel. He was the son of Ahab and Jezebel. He reigned for two years (852-851 BC).
After Ahab's death, the country of Moab, which had earlier been subjugated by Israel, declared its independence, and refused to continue paying tribute to Israel. Ahaziah suffered other losses, including his health. He fell off the balcony of his palace in Samaria and was seriously injured. Instead of turning to the Lord, he sent messages to the temple of a pagan god, Baalzebub, at Ekron, to ask whether he would recover from his injuries.
But the prophet Elijah intercepted the messengers and told that them that because Ahaziah had chosen to inquire of a pagan god, rather than the Lord, that he would not leave the bed that he was lying on and that he would die. Ahaziah did die, just as Elijah had said. Ahaziah's brother, Jehoram, became the new king, because Ahaziah did not have a son to succeed him. The name Ahaziah means "Yah holds firm." The story of Ahaziah is found in 1 Kings 22:40-53 and in 2 Kings, chapter 1.
Ahaziah reigned for one year (843-842 BC) as the king of Judah when he was 22 years old. He was the son of Jehoram. His mother, Athaliah, was King Ahab's daughter. He had many of the same failings as did King Ahab, and his mother encouraged him in doing wrong.
He made an alliance with King Jehoram of Israel (son of Ahab). Jehoram (not to be confused with King Jehoram of Judah) was wounded in a battle with Syria, and returned to Jezreel to recover. Ahaziah went to visit him, but this was a fatal mistake, for God had decided to punish Ahaziah for his alliance with Jehoram. Jehu, who was earlier anointed by one of Elisha's young prophets, as the man to wipe out the family of Ahab, was hunting down and killing the family and friends of Ahab. When he found Ahaziah hiding in Samaria, he killed him.
When Ahaziah's mother, Athaliah, found out that her son was dead, she killed her grandsons, except for Joash. Joash was rescued and hidden in a storage room of the Temple by his Aunt Jehoshabeath, who was King Ahaziah's sister. Athaliah then became queen and reigned for six years. Ahaziah was given a royal burial, because he was the grandson of King Jehoshaphat. The story of Ahaziah is found in 2 Chronicles, chapter 22. The name Ahaziah means "Yah holds firm."
