The Vulgate makes it "...reservate vobis" KJV et cetera follow this.18 καὶ πᾶσαν τὴν ἀπαρτίαν τῶν γυναικῶν, ἥτις οὐκ οἶδε κοίτην ἄρσενος, ζωγρήσατε αὐτάς.
Is that self-evident?
"αὐτάς" is accusative, and "ζωγρήσατε" is "capture/tear away alive".
Is the understanding of "αὐτάς" referring to the plurality of virgins out of the question?
To illustrate my problem:
In German you would refer to a Mannschaft (team) as "she" (jaja get over it)
while in English you would refer to the national team as "they" blundered again.
In German the grammatical numerus prevails while in English the natural ones.
If the Greeks (or Hebrews, for that matter) looked at it the English way, " αὐτάς" referring to the virgins would be a possibilty, wouldn't it?
