(35, 36) But if the scall spread.—If, after the scall had remained stationary for a fortnight, and the patient had been pronounced clean, he is brought again because the scall had spread after the lapse of the two quarantines, he is to be forthwith pronounced unclean, whether it was accompanied by yellow hair or not.

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.

But if the eruption spread even after his purification, the priest, on seeing this, was not to look for yellow hair. "He is unclean:" that is to say, he was to pronounce him unclean without searching for yellow hairs; the spread of the eruption was a sufficient proof of the leprosy.

אחרי טהרתו [AND IF THE SCALL SPREADS AT ALL …] AFTER HIS BEING PRONOUNCED CLEAN — I have here only the statement that he is unclean if it spreads after he has been freed from the quarantine; whence do I know that the same applies if it has spread by the end of the first week and or by the end of the second week? Because it states here: “if it spreads at all” (Sifra, Tazria Parashat Nega'im, Chapter 9 9).
