With hypocritical mockers in feasts, they gnashed upon me with their teeth.
With hypocritical mockers in feasts - rather, 'with hypocritical (or profane) mockers for a cake' х maa`owg (H4580)]; such as sell their tongue to raillery for the sake of a paltry 'cake' (not a dainty cake, but the ordinary ashes-baked cake of bread used in the East), ingratiating themselves with some leader of the persecution by ribald scoffs at the godly sufferer. It is not refined wit that is meant, but bitter scoffs of the lowest, hounded on by the master from whom they receive their morsel.
They gnashed ... - with vehement fury (Psalms 37:12; Acts 7:54).
