1 Nephi 10:21

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.

and no unclean thing can dwell with God; wherefore, ye must be cast off forever.
