Charles Ellicott Commentary Leviticus 13:4

"And if the bright spot be white in the skin of his flesh, and the appearance thereof be not deeper than the skin, and the hair thereof be not turned white, then the priest shall shut up [him that hath] the plague seven days:" — Leviticus 13:4 (ASV)

If the bright spot be white. —But if upon inspection there merely appeared a white spot in the skin, and the previously mentioned two symptoms were absent, the case was not yet decided.

Then the priest shall shut up him that hath the plague. —The suspected individual was to be separated from the rest of the community for seven days, during which time it would be seen whether the condition actually developed into this disorder. According to the canons that were in effect during the second Temple, if a bridegroom was seized with this disease, he was not to be isolated during the wedding week. It can be seen that the words “him that hath” are in italics, thus indicating that they are not in the text; but “plague” here, as we have seen in Leviticus 13:3, denotes plagued person.
