The LORD spoke to Ahaz, saying:
Ask for a sign from the LORD, your God; let it be deep as the nether world, or high as the sky!
But Ahaz answered, "I will not ask! I... will not tempt the LORD!"
Then he said: Listen, O house of David! Is it not enough for you to weary men, must you also weary my God?
Therefore the Lord himself will give you this sign: the virgin shall be with child, and bear a son, and shall name him Emmanuel.
which means “God is with us!”
