Then his master will punish him severely and assign him a place with the hypocrites. In that place there will be weeping and gnashing of teeth."

the master of that servant will come on a day when he doesn't expect him and at an hour that he doesn't know. Then his master will punish him severely and assign him a place with unfaithful people.

Not many of you should become teachers, my brothers, because you know that we who teach will be judged more severely than others.
