2 Kings 16:5-7

5At that time King Rezin of Syria and King Pekah son of Remaliah of Israel attacked Jerusalem. They besieged Ahaz, but were unable to conquer him.

6(At that time King Rezin of Syria recovered Elat for Syria; he drove the Judahites from there. Syrians arrived in Elat and live there to this very day.)

7Ahaz 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.”
