Matthew Poole and continuators on Leviticus 13:4

4 If the bright spot be white in the skin of his flesh, and in sight 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 dayes.

For greater assurance: to teach Ministers not to be rash nor hasty in their judgments and censures, but diligently to search and examine all things before-hand. The plague is here put for the man that hath the plague, as pride is put for a proud man, Ier. 50. 31. and dreamers, Ier. 27. 9.
