the priest shall examine the infection, and if it appears to be deeper than the skin and the hair in it is yellow and thin, the priest must pronounce him unclean; it is a scaly outbreak, an infectious disease of the head or chin.
KJV
Then the priest shall see the plague: and, behold, if it [be] in sight deeper than the skin; [and there be] in it a yellow thin hair; then the priest shall pronounce him unclean: it [is] a dry scall, [even] a leprosy upon the head or beard.
ASV
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.
