This question recently jumped to the top of the list. A related question could be something more like:
Who are the young woman and the son from Isaiah 7.14 referring to?
But while the above example is related to the one that was actually asked, there does not seem to be a way to trim or edit the current question so that it does not reflect that specifically Christian perspective. The actual question asked requires a systematic Christian framework, so it seems it should be moved over to Christianity.SE.
(Still being relatively new to SE's features, I'm not aware if this is the appropriate place to make this suggestion.)
