Isaiah 7:10, 11, 12, 13, 14

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.
