7:14 Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.
9:6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.
I'm guessing that several passages in this section will make my Christian readers jump up and down and yell at me "See this? This is prophesy that predicts the birth of Jesus!!!! Told you so!!!"
Well, go ahead.
But aside from the inconsistency of the name, Emmanuel (which happens again in the Gospel of Matthew), the prophesy is fairly general and isn't it more likely that the story of Jesus was rooted in these passages as a way to tie him into the Old Testament?
