Hello all, 
I am sure this question will be answered when the Learn Greek and Hebrew with Logos Bible Software video's are actually published but I am not really wanting to wait that long.  My question goes back to my original Wow or Huh post.  
I do not know the languages and want to see if I can figure out why the singular He is better than They in Genesis 3 15.  ((At least I am assuming this))  But I am asking what I need to do to really get after it.  I guess one thing might be do a passage search in my library for this verse.  Next, I would need a word(s) search?  What word(s) to search?  Would the english word search help?  I assume the original language search is the best...so I will do that as well. 
What might be the best is someone talk me through what to search and how.  I was hoping that I would be able to highlight the original language from a interlinear or reverse interlinear and search with that.  I read in another thread that the reverse interlinear or interlinear (don't remember which one) was an abomination.  Do they not have the text of the BHS or NA27 or a "good" original language text? 
Do I just need to stop trying to study the original until I get at least more of a basic knowledge of greek and hebrew grammar and such?
