At one point in his reign, Ahaz faced a serious crisis. The kings of Syria and Israel attacked Judah. They planned to remove Ahaz and force Judah to join them in resisting Assyria.
Instead of trusting the Lord, Ahaz asked Assyria for help (2 Kings 16:7–10). By doing this, he rejected Isaiah’s call to trust in God (Isaiah 7:12).
The Assyrians defeated Syria and Israel. In time, both nations fell. However, Assyria later turned against Judah and sought to control it completely.
