In the seventeenth year of the reign of Pekah son of Remaliah as king of Israel, Ahaz son of Jotham became king of Judah
at the age of twenty, and he ruled in Jerusalem for sixteen years. He did not follow the good example of his ancestor King David; instead, he did what was not pleasing to the Lord his God
and followed the example of the kings of Israel. He even sacrificed his own son as a burnt offering to idols, imitating the disgusting practice of the people whom the Lord had driven out of the land as the Israelites advanced. 1

Ahaz sent men to Tiglath Pileser, the emperor of Assyria, with this message: "I am your devoted servant. Come and rescue me from the kings of Syria and of Israel, who are attacking me."
Ahaz took the silver and gold from the Temple and the palace treasury, and sent it as a present to the emperor.
Tiglath Pileser, in answer to Ahaz' plea, marched out with his army against Damascus, captured it, killed King Rezin, and took the people to Kir as prisoners.
When King Ahaz went to Damascus to meet Emperor Tiglath Pileser, he saw the altar there and sent back to Uriah the priest an exact model of it, down to the smallest details.
So Uriah built an altar just like it and finished it before Ahaz returned.
On his return from Damascus, Ahaz saw that the altar was finished,
so he burned animal sacrifices and grain offerings on it and poured a wine offering and the blood of a fellowship offering on it.
The bronze altar dedicated to the Lord was between the new altar and the Temple, so Ahaz moved it to the north side of his new altar. 3

Uriah did as the king commanded.
