Isaiah prophesied from around 740 to 687 B.C. during the reign of four kings: Uzziah, Jotham, Ahaz, and Hezekiah. Ahaz was a wicked king who locked up the doors of the temple in Jerusalem, burned his sons in fire, cut the vessels of the temple to pieces, and made Judah a vassal state of the Assyrian king Tiglath-pileser by paying him for protection (2 Kings 16:8, 10). Ahaz’s son, Hezekiah, came to the throne at twenty-five years old and called for a recovery of the Passover festival in Jerusalem. That assembly of joy was so grand the like had not been seen since the days of David and Solomon (2 Chronicles 30:26). But the Assyrian threat was looming. They took Samaria in the sixth year of Hezekiah’s reign. And by the fourteenth year of his rule, the Assyrian king Sennacherib had come against Judah and Jerusalem.
