Mary forbade them, saying: It cannot be that I should know a man, or that a man should know me.

That's a strange turn of phrase in any language.

"I'm not even going to give blowjobs" doesn't sound like a very (pseudo-)Biblical utterance but it's one of the few meanings I can give to it. How else do you separate sexual acts between men and women into two distinct component acts that be renounced individually?
