Numbers can present translation problems, differing manuscripts, words omitted by editors, etc. But basically a seven is a seven.  If the number set works to produce the 70 x 7, then it does (math works regardless of language). 

Interesting that Paul doesn't mention the Mary's, the fragmented remnants of Her.  Paul doesn't have 'bridegroom' either.  You have to wonder how much of the NT writings are reactionary and sectarian. For example, Acts portrayal of the communal living of the first Christians where everything is shared. Doesn't seem entirely realistic.  What is the author trying to prove?  Because Paul did not mention Mary Magdalene, a major character in the Gospel of Mary at least, does that mean she did not exist? Or Paul simply refused to acknowledge her work? Paul evidently needed James and Peter or at least a connection to the Jerusalem group to validate himself. Or he needed people to believe he had that connection.
