TSK · John 20:4

then the priest shall look on the plague; and, behold, if the appearance thereof be deeper than the skin, and there be in it yellow thin hair, then the priest shall pronounce him unclean: it is a scall, it is leprosy of the head or of the beard.

Know ye not that they that run in a race run all, but one receiveth the prize? Even so run; that ye may attain.
