Это говорю я для того, чтобы кто-нибудь не прельстил вас вкрадчивыми словами;
I tell you this so that no one may deceive you by fine-sounding arguments.
I say this in order that no one may delude you with plausible arguments.
I say this so that no one will delude you with persuasive argument.
I am telling you this so no one will deceive you with well-crafted arguments.
And this I say, lest any man should beguile you with enticing words.
Now this I say lest anyone should deceive you with persuasive words.
And I say this to the end that no one may delude you by persuasive speech.
