Ahaz (reigned 735-715 bc), son of Jotham (reigned 742-735 bc), and 12th king of Judah. Judah was attacked early in his reign by King Pekah of Israel (737-732 bc) and King Rezin of Syria (reigned about 742-732 bc), who attempted to force Ahaz into a coalition against Assyria. Additional incursions were made into Judean territory by the Edomites, to whom Ahaz was forced to give up the important city of Elath (now Al ‘Aqabah, Jordan). Ahaz asked help of the Assyrian king Tiglath-pileser III (r. 745-727 bc), who drove out the invaders but in return exacted tribute from Judah. Ahaz made various changes in the temple service and paid homage to the Assyrian gods. He was denounced for infidelity to Yahweh by the Hebrew prophet Isaiah, who opposed the alliance with Assyria. In 715 bc Ahaz was succeeded by his son Hezekiah.
