God sends Isaiah and another prophet to reassure King Ahaz during a time of crisis for the people of Judah. God offers Ahaz a sign that a virgin will conceive and bear a son named Immanuel, meaning "God with us". This prophecy is fulfilled by the virgin birth of Jesus Christ, who is God present with humanity. Though Ahaz refuses the sign, the prophecy signifies God's power and control over the situation, and verifies his promise of presence with his people.
