Josiah
A:The Bible says that Ahaziah was king of Israel for about two years (approx 852-851 BCE). Another Ahaziah is recorded as king of Judah for one year (approx 843-842 BCE). Ahab's successors in Israel were his sons Ahaziah (parts of two years) and Jehoram (roughly seven according to 2 Chronicles, though the Deuteronomist gives him twelve years). In Judah, Jehoram, son of Jehoshaphat reigned for at least seven years and Jehoram's son Ahaziah for less than a year. This means that Ahaziah and Jehoram ruled Israel for about eight years, and also that Jehoram and Ahaziah ruled Judah during approximately the same eight years.The duplication of the names, even if in reverse order, is startling and has led to speculation that Judah was really under Israelite rule for this period, which the southern scribes were unwilling to acknowledge. We will probably never know for certain, but it is possible that Ahaziah, son of Ahab, really was king of both Israel and a defeated Judah (followed by his brother Jehoram).
Jezebel, the wife of King Ahab in the Hebrew Bible, had three children named Ahaziah, Jehoram (also known as Joram), and Athaliah. Ahaziah succeeded Ahab as king of Israel, while Jehoram also became king later. Athaliah was notable for becoming queen and ruling Judah.
Some believe that the passage in 2 Chronicles is actually speaking of the 'true' ruler's age - Athaliah, his mother being 42 years old. An interesting argument is presented in the Related Links for your reading pleasure.
After King Ahab's death, his son Ahaziah became the king of Israel. However, Ahaziah ruled for a short time before he was succeeded by his brother Jehoram (also known as Joram). Jehoram reigned over Israel and continued the legacy of his father, Ahab, in following the practices of the house of Ahab.
Ahaziah, king of Judah, died as a result of injuries sustained from a fall through a lattice in his upper chamber. The incident left him gravely ill, and he ultimately sought counsel from Baal-zebub, the god of Ekron, instead of seeking guidance from the Lord. As a result, the prophet Elijah delivered a message of judgment, declaring that Ahaziah would not recover from his injuries, which ultimately came to pass. He died shortly thereafter, and his reign was noted for its idolatry and departure from the worship of Yahweh.
The 44th King of Israel was King Ahaziah, who reigned over the northern kingdom of Israel for a brief period, approximately two years. He was the son of Ahab and Jezebel and is known for continuing the idolatrous practices of his parents. His reign ended when he was mortally wounded in a fall and subsequently died, leading to the ascension of his brother, Jehoram. Ahaziah's rule is noted for its alignment with the worship of Baal and conflict with the prophets of Yahweh.
