Isaiah 7:10-14

Later, the LORD sent this message to King Ahaz: “Ask the LORD your God for a sign of confirmation, Ahaz. Make it as difficult as you want—as high as heaven or as deep as the place of the dead.” But the king refused. “No,” he said, “I will not test the LORD like that.” Then Isaiah said, “Listen well, you royal family of David! Isn’t it enough to exhaust human patience? Must you exhaust the patience of my God as well? All right then, the Lord himself will give you the sign. Look! The virgin will conceive a child! She will give birth to a son and will call him Immanuel (which means ‘God is with us’).
