During Pekah's reign over Israel, King Tiglath-pileser of Assyria came and captured Ijon, Abel Beth Maacah, Janoah, Kedesh, Hazor, Gilead, and Galilee, including all the territory of Naphtali. He deported the people to Assyria.

Ahaz sent messengers to King Tiglath-pileser of Assyria, saying, "I am your servant and your dependent. March up and rescue me from the power of the king of Syria and the king of Israel, who have attacked me."

When King Ahaz went to meet with King Tiglath-pileser of Assyria in Damascus, he saw the altar there. King Ahaz sent to Uriah the priest a drawing of the altar and a blueprint for its design.
