And Tilgathpilneser king of Assyria came unto him,.... Not to Jerusalem, but to Damascus, where he made a diversion in his favour, and took that city, and where Ahaz met him, Kg2 16:9. and distressed him, but strengthened him not; exhausted his treasures, and laid a tribute upon him, but did not help him against the Edomites and Philistines, or recover for him the cities they had taken from him; and, in taking Damascus, he served himself more than Ahaz, and paved the way for seizing upon the ten tribes.
