Ahaz, the Syro-Ephraimite Crisis, and the Immanuel Prophecy

The event

Ahaz faced a genuine crisis early in his reign: King Rezin of Aram (Syria) and King Pekah of Israel joined forces to attack Jerusalem, aiming to depose Ahaz and install a puppet king of their own choosing. Scripture says his heart "shook as the trees of the forest shake with the wind." The Lord sent Isaiah to meet Ahaz with a message of reassurance: these two threatening kings were nothing more than "two stubs of smoldering firebrands," and their plan would not stand.

Isaiah told Ahaz to ask for a sign confirming this, but Ahaz — already secretly negotiating with Assyria for help — refused, hiding behind false piety: "I will not ask, nor will I test the LORD!" Isaiah gave him a sign anyway, one that reached far beyond Ahaz's immediate crisis: "the virgin will be with child and bear a son, and she will call His name Immanuel," meaning "God with us" — a promise Matthew's Gospel identifies as fulfilled in the virgin birth of Jesus Christ.

Ahaz went on to buy Assyrian help with Temple and palace treasures, and even had a pagan altar modeled on one he'd seen in Damascus installed in the Temple courtyard itself — trading God's clear promise for a foreign king's protection, and dragging Judah's worship further from faithfulness in the bargain.

Dating

Ahaz's full reign is usually dated c. 735–715 BC in Thiele's chronology (including coregency); the Syro-Ephraimite crisis and Immanuel sign belong to its earliest years, c. 735–732 BC.
