King of Judah, 735–715 BCE. The Assyrians were dominant, and Syria and Ephraim resolved to arrest their eastward expansion and tried to force Judah to join their coalition but Ahaz refused; Rezin of Syria and Pekah of Israel determined to replace Ahaz with Tabeel's son (2 Kgs. 16: 5; Isa. 7: 1–25). Isaiah supported Ahaz, but did not approve of his appeal to Tiglath-Pileser to rescue him from the Syro-Ephraimite conspirators. When Damascus, the capital of Syria, fell, Ahaz hastened to meet Tiglath-Pileser there. While he was in that city, Ahaz was attracted to a heathen altar and had a replica installed in Jerusalem.
