Again the LORD spoke to Ahaz: Ask for a sign from the LORD, your God; let it be deep as Sheol, or high as the sky! But Ahaz answered, “I will not ask! I will not tempt the LORD!” Then he said: Listen, house of David! Is it not enough that you weary human beings? Must you also weary my God? Therefore the Lord himself will give you a sign; the young woman, pregnant and about to bear a son, shall name him Emmanuel.
Isaiah 7:10–14
