2 Kings 16:5-6

Then Rezin king of Aram and Pekah son of Remaliah king of Israel ganged up against Jerusalem, throwing a siege around the city, but they couldn’t make further headway against Ahaz. At about this same time and on another front, the king of Edom recovered the port of Elath and expelled the men of Judah. The Edomites occupied Elath and have been there ever since.
