There were 'signs' in the minor and major prophets.
They were always for the immediate generation, for the situation they were in then, not for some ambigious future though. The signs were , of course, always written about after they had come about.
The Jewish concept of prophecy was not predicting for the future, but rahter messages to guild the living back to the path of rightiousness at the momment.
If you look at all the phrases that Christians take for predicting Jesus IN CONTEXT, they never point to some event hundreds of years in the future, but rather something that has occured at the writing,or is
occuring at the writing of those passages. Taking one or two phrases out of context, then taking another one or two phrases out of context from a book several hundred years later to back it up is not prediction the future, but rather shoehorning 'Predictions' into place to make it appear that something miraculous has happened.
Oh.. and then relationing at story, and using out of context phrases as if they were predictions is a dishonest technique to. The writer of the Gospel of Matthew was particularly fond of that.
