The altar of Damascus is built in Jerusalem (2 Kings 16:10-16:16)

“When King Ahaz went to Damascus to meet King Tiglath-pileser of Assyria, he saw the altar that was at Damascus. King Ahaz sent to the priest Uriah a model of the altar, and its pattern, exact in all its details. The priest Uriah built the altar, in accordance with all that King Ahaz had sent from Damascus. The priest Uriah built it just so, before King Ahaz arrived from Damascus. When the king came from Damascus, he viewed the altar. Then the king drew near to the altar. He went up on it. He offered his burnt offering and his grain offering, poured his drink offering, and dashed the blood of his offerings of well–being against the altar. The bronze altar which was before Yahweh he removed from the front of the house, from the place between his altar and the house of Yahweh. He put it on the north side of his altar. King Ahaz commanded the priest Uriah, saying. ‘Upon the great altar offer the morning burnt offering, the evening grain offering, the king’s burnt offering, and his grain offering, with the burnt offering of all the people of the land, with their grain offering and their drink offering. Then dash against it all the blood of the burnt offering and all the blood of the sacrifice. The bronze altar shall be for me to inquire by.’ Uriah the priest did everything that King Ahaz commanded.”

When in Damascus to see King Tiglath-pileser III, King Ahaz was enamored by the altar he saw in Damascus. He wanted the same kind of altar in Jerusalem. He sent a model to the priest Uriah to build it like his model. Uriah accomplished this before the king arrived from Damascus. King Ahaz then offered all the normal sacrifices as laid out in Exodus and Leviticus about burnt offerings, grain offerings, and the offerings of well-being. Then he told the priest Uriah that he wanted all the sacrifices done on this altar. They then put aside the bronze altar that had been there.

The attack of the King of Assyria (2 Kings 15:29-15:29)

“In the days of King Pekah of Israel, King Tiglath-pileser of Assyria came and captured Ijon, Abel-beth-maacah, Janoah, Kedesh, Hazor, Gilead, Galilee, and all the land of Naphtali. He carried the people captive to Assyria.”

Wow! This is serious. That King Pul, who took money during the reign of King Menahem, wanted territory this time. This King Tiglath-pileser III captured the northern territory of Israel, including all of Naphtali plus other cities. He was the first to displace the Israelites. He took captives from these northern cities and brought them to Assyria, which today might include parts of Syria, Iraq, and Iran. Iran was more Persian. Iraq was more Babylonian. This is the beginning of the Assyrian captivity that more or less began with King Menahem.
