In the history of the Southern Kingdom of Judah, there was a monarch who became infamous for his heinous sins and apostasy, and that was King Ahaz. Ahaz was the son of King Uzziah of Judah, and he was the twelfth king in the sequence of Judah's kings, with his reign approximately from 735 BC to 715 BC.
Ahaz's rule did not start solely from the beginning; he initially co-ruled with his father Uzziah until Uzziah's death, after which Ahaz took on the responsibilities of kingship alone. Ahaz ascended the throne at the age of 20 and co-ruled with his father until he was 24, then ruled alone for 16 years. However, Ahaz did not follow in his father's path of faith but instead embarked on a path of evil.
Ahaz's sins were multifaceted. Unlike his ancestor David, who walked in the ways that were right in the sight of the Holy One, Ahaz instead "walked in the ways of the kings of Israel," adopting pagan beliefs and customs. He cast images of Baal and burned his own sons as sacrifices in the Valley of Hinnom, an act detestable to the Holy One. Additionally, Ahaz offered sacrifices and burned incense on the high places, hills, and under green trees, completely forsaking the path of faith.
During Ahaz's reign, the kingdom of Judah faced severe crises. To secure his throne, he did not hesitate to seek aid from the Assyrian Empire, referring to himself as the "servant and son" of the king of Assyria, and gave all the gold and silver from the temple and the royal treasury as gifts to the king of Assyria. This act not only demonstrated his weakness and betrayal but also constituted an act of treachery for personal gain. However, even so, the king of Assyria, Tiglath-Pileser III, did not truly help him but instead bullied him when he needed help the most.
Ahaz's reign ultimately ended in failure. After his death, he was not buried in the tombs of the kings of Israel, which was a form of punishment and humiliation for his apostasy and sinful deeds. His son Hezekiah succeeded him as king of Judah. Hezekiah was a stark contrast to his father, adhering to the path of faith and bringing a period of revival to the kingdom of Judah.
