2 Kings 16:5-7

5Then King Rezin of Aram and King Pekah of Israel came up to attack Jerusalem. They besieged Ahaz but could not conquer him.

6At that time the king of Edom recovered the town of Elath for Edom. He drove out the people of Judah and sent Edomites to live there, as they do to this day.

7King Ahaz sent messengers to King Tiglath-pileser of Assyria with this message: “I am your servant and your vassal. Come up and rescue me from the attacking armies of Aram and Israel.”
