Ahaz, son of Jotham, becomes king at twenty and reigns sixteen years in Jerusalem. He does not do what is right like David his father but walks in the way of the kings of Israel; he even makes his son pass through the fire, following the abominable practices of the nations, and offers sacrifices at the high places, on the hills and under every green tree.
Rezin, king of Aram, and Pekah, king of Israel, go up against Jerusalem and besiege it, but cannot overcome it. At that time Rezin recovers Elath for Aram and drives out the men of Judah. Ahaz sends messengers to Tiglath-pileser, king of Assyria, saying that he is his servant and son, and asking him to come and save him from Aram and Israel. He takes the silver and gold found in the temple and the palace and sends them as a present. The king of Assyria listens, goes up against Damascus, captures it, carries its people into exile and kills Rezin.
Ahaz goes to Damascus to meet Tiglath-pileser. There he sees an altar and sends Uriah the priest a pattern and plan so he can build one like it. Uriah does so before Ahaz returns. Ahaz goes up to the altar, offers sacrifices and keeps it. He moves the bronze altar that stood before the Lord and puts it on the north side of the new altar. He orders Uriah to offer the burnt offerings on the new altar, and the bronze altar will be for him to inquire by. He also cuts off the frames of the stands, removes the basin from the bronze oxen and sets it on a stone pavement, and removes the covered way from the temple because of the king of Assyria.
Ahaz dies and is buried with his fathers. His son Hezekiah reigns in his place.
