Summary: Ahaz refuses to ask for a sign, but God gives one anyway: a child will be born, and his name will be Emmanuel.
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 Isaiah said: Listen, O house of David! Is it not enough for you to weary people, 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!”
