God promises that Judah will be protected from Syria and Israel, who plan to invade. The prophet Isaiah is sent to reassure King Ahaz of Judah, telling him not to be afraid and promising that the invading kingdoms will be destroyed within 65 years. However, when offered a sign by God, Ahaz refuses. So God himself promises a sign: a virgin will conceive and bear a son named Immanuel. Before this child is old enough, the threatened kingdoms will be destroyed by Assyria. Ahaz later submits to Assyria instead of trusting in God's promise of protection.
