Leviticus 13:4 Meaning and Commentary

Leviticus 13:4

If the bright spot be white in the skin of his flesh
The Targum of Jonathan is, white as chalk in the skin of his flesh; but other Jewish writers make the whiteness of the bright spot to be the greatest of all, like that of snow; (See Gill on Leviticus 13:2):

and in sight [be] not deeper than the skin, and the hair thereof
be not turned white;
though it be a bright spot, and be very white, yet these two marks not appearing, it cannot be judged a leprosy, at most it is only suspicious: wherefore

then the priest, shall shut up [him that hath] the plague seven
days;
in whom the bright spot is, and of whom there is a suspicion of the plague of leprosy, but it is not certain; and therefore, in order to take time, and get further knowledge, the person was to be shut up from all company and conversation for the space of seven days; by which time it might be supposed, as Ben Gersom observes, that the case and state of the leprosy (if it was one) would be altered; and Aben Ezra remarks, that most diseases change or alter on the seventh day.

Leviticus 13:4 In-Context

2 "If someone develops on his skin a swelling, scab or bright spot which could develop into the disease tzara'at, he is to be brought to Aharon the cohen or to one of his sons who are cohanim.

3 The cohen is to examine the sore on his skin; if the hair in the sore has turned white, and the sore appears to go deep into the skin, it is tzara'at, and after examining him the cohen is to declare him unclean.

4 If the bright spot on his skin is white, but it does not appear to go deep into the skin, and its hair has not turned white, then the cohen is to isolate him for seven days.

5 On the seventh day the cohen is to examine him again, and if the sore appears the same as before and has not spread on the skin, then the cohen is to isolate him for seven more days.

6 On the seventh day the cohen is to examine him again, and if the sore has faded and hasn't spread on the skin, then the cohen is to declare him clean - it is only a scab, so he is to wash his clothes and be clean.
