Ahaz Sought Help From Assyria

Baal worship climaxed in Judah during the reign of Ahaz (2 Ki 16). Ahaz (about 732-715 B.C.), was faced with Assyria`s rise to power under TiglathPileser III; but Ahaz resisted the urgings of Rezin of Syria and Pekah of Israel to join an alliance against Assyria. Instead, Ahaz sought help from Assyria, against the prophet Isaiah`s advice, and received assistance in return for heavy tribute.
