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.
Then the priest will look at the plague. If it goes deeper than the skin and has a thin yellow hair in it, the priest will say the person is unclean. It's a type of dry scaling called leprosy found on the head or beard.
