Оригинальный текст - Древнегреческий - Ἐφ' οἷς γὰρ μὴ φρονῶ σιγᾶν φιλῶ.

Wrong diacritics. It should be edited this way:

Ἐφ' οἷς γὰρ μὴ φρονῶ σιγᾶν φιλῶ.

It's a quote from the tragedy "Oedipus the King" by Sophocles (line 569).
Could you please ask User10 if I am right and edit the text properly, dear admins?
