Isaiah 7: 10-14
7:10 And the Lord spoke further to Ahaz, saying:
7:11 Ask for a sign for yourself from the Lord your God, from the depths below, even to the heights above.
7:12 And Ahaz said, “I will not ask, for I will not tempt the Lord.”
7:13 And he said: “Then listen, O house of David. Is it such a small thing for you to trouble men, that you must also trouble my God?
7:14 For this reason, the Lord himself will grant to you a sign. Behold, a virgin will conceive, and she will give birth to a son, and his name will be called Immanuel.
