Ahaz turned in his extremity to Assyrian help, and Tiglath-pileser seized the opportunity of accepting the vassalage of Judah, with its strong fortress of Jerusalem, and at the same time of overthrowing both Damascus and Samaria.

Rezon was closely besieged in his capital, while the rest of the Assyrian army was employed in overrunning Samaria, Ammon, Moab, and the Philistines (B.C.

734).

Pekah was put to death, and Hosea appointed by the Assyrians in his place.

After a siege of two years, Damascus fell in B.C.732, Rezon was slain, and his kingdom placed under an Assyrian satrap.
