"Must be cast off"

1. 1 Ne. 10: 21
     21 Wherefore, if ye have sought to do wickedly in the days of your probation, then ye are found unclean before the judgment-seat of God; and no unclean thing can dwell with God; wherefore, ye must be cast off forever.
2. 1 Ne. 15: 33
     33 Wherefore, if they should die in their wickedness they must be cast off also, as to the things which are spiritual, which are pertaining to righteousness; wherefore, they must be brought to stand before God, to be judged of their works; and if their works have been filthiness they must needs be filthy; and if they be filthy it must needs be that they cannot dwell in the kingdom of God; if so, the kingdom of God must be filthy also.
3. Mosiah 27: 27
     27 I say unto you, unless this be the case, they must be cast off; and this I know, because I was like to be cast off.
