And if it spread much abroad in the skin,.... Upon viewing it on the seventh day, though it is not expressed, the swelling or bright spot; or "in spreading spread"; See Gill on Leviticus 13:7; which Ben Gersom interprets, not of the skin of the flesh, but of the ulcer:
then the priest shall pronounce him unclean; even though there are no white hairs in it, nor is it lower than the skin, yet is not at a stand or contracted, but spreading:
it is a plague; or stroke; it is one sort of a leprosy, and such an one as makes a man unclean in a ceremonial sense.
A plague - Or the plague of leprosy, of which he is speaking.
