2 Kings 16:1-5

Ahaz son of Jotham began to rule over Judah in the seventeenth year of King Pekah’s reign in Israel. Ahaz was twenty years old when he became king, and he reigned in Jerusalem sixteen years. He did not do what was pleasing in the sight of the LORD his God, as his ancestor David had done. Instead, he followed the example of the kings of Israel, even sacrificing his own son in the fire. In this way, he followed the detestable practices of the pagan nations the LORD had driven from the land ahead of the Israelites. He offered sacrifices and burned incense at the pagan shrines and on the hills and under every green tree. Then King Rezin of Aram and King Pekah of Israel came up to attack Jerusalem. They besieged Ahaz but could not conquer him.
