2 Kings 16:1-5

In the seventeenth year of Pekah the son of Remaliah Ahaz the son of Jotham king of Judah began to reign. Twenty years old was Ahaz when he began to reign; and he reigned sixteen years in Jerusalem: and he did not that which was right in the eyes of Jehovah his God, like David his father. But he walked in the way of the kings of Israel, yea, and made his son to pass through the fire, according to the abominations of the nations, whom Jehovah cast out from before the children of Israel. And he sacrificed and burnt incense in the high places, and on the hills, and under every green tree. Then Rezin king of Syria and Pekah son of Remaliah king of Israel came up to Jerusalem to war: and they besieged Ahaz, but could not overcome him.
