Does not the very nature of things teach you that if a man has long hair, it is a disgrace to him, (NIV)
Does not the native sense of propriety (experience, common sense, reason) itself teach you that for a man to wear long hair is a dishonor [humiliating and degrading] to him, (AMP)
Doth not even nature itself teach you, that, if a man have long hair, it is a shame unto him? (KJV)
