Leviticus 13:37 Meaning and Commentary

Leviticus 13:37

But if the scall be in his sight at a stay
If in a few days, or in a short space of time after this, it should appear that the scall is at a full stop, and does not spread any further at all: and [that] there is black hair grown up therein;
which is a sign of health and soundness, and so of purity; yea, if it was green or red, so be it, it was not yellow, according to Jarchi, it was sufficient: the scall is healed;
from whence it appears that it had been a leprous scall, but was now healed, an entire stop being put to the spread of it; and though yellow hairs might have appeared in it, yet, as Gersom observes, two black hairs having grown up in it, it was a clear case that the corruption of the blood had departed, and it had returned to its former state: he [is] clean, and the priest shall pronounce him clean;
he was clean before, and is the reason why he pronounces him so; wherefore it is not the sentence of the priest, but the truth of his case that makes him clean; teaching, as Ainsworth observes, that the truth of a man's estate, discerned by the word and law of God, made the man clean or unclean, and not the sentence of the priest, if it swerved from the law.

Leviticus 13:37 In-Context

35 But if the scabby sore begins to spread after the person is pronounced clean,

36 the priest must do another examination. If he finds that the sore has spread, the priest does not need to look for yellow hair. The infected person is ceremonially unclean.

37 But if the color of the scabby sore does not change and black hair has grown on it, it has healed. The priest will then pronounce the person ceremonially clean.

38 “If anyone, either a man or woman, has shiny white patches on the skin,

39 the priest must examine the affected area. If he finds that the shiny patches are only pale white, this is a harmless skin rash, and the person is ceremonially clean.
