Leviticus 13:22 Meaning and Commentary

Leviticus 13:22

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.

Leviticus 13:22 In-Context

20 "The priest must look at the boil carefully. Suppose it seems to be under the skin. And suppose the hair in it has turned white. Then the priest must announce that the person is 'unclean.' A skin disease has broken out where the boil was.

21 "But suppose that when the priest looks at the boil carefully, there is no white hair in it. The boil is not under the skin. And it has faded. Then the priest must make the person stay away from everyone else for seven days.

22 If the boil is spreading in the skin, the priest must announce that the person is 'unclean.' He has a skin disease.

23 "But suppose the spot has not changed. And suppose it has not spread. Then it is only a scar from the boil. And the priest must announce that the person is 'clean.'

24 "Suppose someone has a burn on his skin. And suppose a white or shiny pink spot shows up in the open sores of the burn.
