So Ahaz sent messengers to Tiglath-pileser king of Assyria, saying, “I am your servant and your son; come up and save me from the hand of the king of Aram, and from the hand of the king of Israel, who are rising up against me.”

And Ahaz took the silver and gold that was found in the house of the Lord and in the treasuries of the king’s house, and sent a gift to the king of Assyria.

So the king of Assyria listened to him; and the king of Assyria went up against Damascus and captured it, and led the people of it into exile to Kir, and put Rezin to death. Damascus Falls
