Isaiah 7:10-14

Then the LORD spoke to Ahaz again, saying, “Ask for a sign from the LORD your God to prove to yourself that these things are true. It may be a sign from as deep as the place of the dead or as high as the heavens.” But Ahaz said, “I will not ask for a sign or test the LORD.” Then Isaiah said, “Ahaz, descendant of David, listen carefully! Isn’t it bad enough that you wear out the patience of people? Do you also have to wear out the patience of my God? The Lord himself will give you a sign: The virgin will be pregnant. She will have a son, and she will name him Immanuel.
