I was just looking at a book I bought for an Old Testament Class that I am taking through my local community college.  I am going to reference Genesis 3: 15.  I have always been told this is the first reference to the Savior.   Well my problem is this... The Tanakh has "they" shall strike at your head"  I did some checking with other translations and all of the others had "he" while the KJV had "it"  I clicked on the interlinears when possible and it seems the word is singular masculine..  Is this just a typo?  Really strange?
