and shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth.

they shall cast the wicked into the furnace of fire: there shall be wailing and gnashing of teeth.

then said the king to the servants, bind him hand and foot, take him away, and turn him out in the dark: there shall be weeping and gnashing of teeth.

and shall turn him out of the family, and give him the reward due to such behaviour: there shall be weeping and gnashing of teeth.

take then that worthless fellow, turn him out in the dark, there shall be weeping and gnashing of teeth.
