Isaiah Seven 14 - Is the Virgin a Virgin?

The virgin will conceive and give birth to a son, and i will call him emmanuel. That is the from isaiah seven 14. But nowhere in isaiah does it say anything about this being about the messiah. This is just another little piece of shapeshire called bingo twice, rightsombody's already cherry picked. So you you have people writing constantly about how, oh, well, this is a prophecy that needed a double fulfilment. Bright is just saying a like the prophet said, and sometimes he would quote it, sometimes he wouldn't.
