כל ספק נגעים חוץ מזה – [this relates to Chapter 4, Mishnah 11 towards the end of the Mishnah] – that the doubt regarding the bright white spot in the flesh preceded [or] the doubt about whether the white hair preceded.

הרי היא כסלע – it became as wide and as large as a Sela.

ספק היא היא – and it is worthy/fit [for the person] to be declared a certified leper, for it spread.

ספק שאחרת באה תחתיה – that the first went away/disappeared and he is fit to be shut up/isolated, for spreading does not defile at the outset.

ומחליטו – and he declares him to be a certified leper.

הלך שער לבן – that he had been certified as a leper for its sake [of the white hair].

וחזר שער לבן – other in its place.

וכן במחיה וכן בפשיון – or that the white hair did not return, but rather that quick flesh resulted which is also a sign of defilement, or that the plague spread.

בתחילה בסוף שבוע ראשון – that is to say, whether the declaration of being a certified leper had been at the outset when he was brought to the Kohen, whether at the end of the first week, whether at the end of the second week, whether after the clearance/release, as for example, that it remained unchanged/עמד בעיניו for two weeks and he released him, and after the release, the white hair came and he (i.e., the Kohen) declared him to be a certified leper, in all of these ways if the white hair disappeared and then the white hair returned, or the quick flesh or the spreading. הרי היא כמות שהיתה – that is to say, the defilement remained like it was, for since he has a sign of defilement, even though this is not the same sign that he had at the time of the declaration as a certified leper.

וחזר הפשיון וכן בשער לבן – but that it (i.e., the Mishnah) doesn’t teach, "וכן המחיה"/and similarly the quick flesh, because when the spreading disappeared and the quick flesh came, sometimes he would be pure, as for example, that the quick flesh diminished the plague from being the size of a split Cilician bean.

שער פקודה (hair of a leprous spot which remains after the inflammation has partly receded) – it is language of פקדון/deposit (see Leviticus 5:21 and 5:23), that the bright white spot in the flesh/בהרת deposited the hair in the skin of the flesh and left it/disappeared.

וחכמים מטהרים – and their reasoning, as it is written (Leviticus 13:10): “[If the priest finds on the skin a white swelling] which has turned some hair white, [with a patch of un-discolored flesh in the swelling].”/"והיא הפכה [שער לבן ומחית בשר חי בשאת]., that it has turned [some hair white], but it did not turn its neighboring [hair white].

אף דבריך אין מקויימין – for this also is pure. And the Halakha is according to the Sages.

בין אישר אחד – even though that which ever you turn, he has one bright white spot in the flesh that has spread, that which at its outset was like a split Cilician bean and now is like a Sela, he is fit to be declared a certified leper, nevertheless, since he (i.e., the Kohen) doesn’t know on which plague is declaring him to be a certified leper, he (i.e., the person) is pure, from the decree of the Scriptural verse, as it is written (Leviticus 13:22): “If it should spread in the skin, the priest shall pronounce him impure; [it is an affection],” the definitive plague he declares impure, but he doesn’t declare impure but he doesn’t defile the plague where he has doubt.

בין בשני אנשים – even though that one of them requires being shut up/isolated for seven days a second time at the end of the first week, and the other is a certified leper, but sine he doesn’t know which to shut up and which to declare a certified leper, both of them are pure from the decree from the Scriptural verse.

ר' עקיבא אומר כו' – but the Halakha is not according to Rabbi Akiba.

שניהם טמאים – since it spread in both of them.

אף על פי שחזרו להיות כסלע – for now one of them is ritually pure, but since they were obliged to regard themselves/obligate themselves for defilement, both of them are impure, as it is written (Leviticus 13:23): “[But if the discoloration remains stationary, not having spread, it is the scar of the inflammation] the priest shall declare him pure”/"וטהרו הכהן" - that which is definitive, he (i.e., the Kohen) declares pure, but he does not declare pure the doubtful (see also Sifra on his verse in Leviticus).

עד שיחזרו להיות גריס – that now, certainly both of them are ritually pure, that the spreading that on whose account they were declared to be certified lepers has disappeared from both of them.
