Commento su Levitico 14:48

ואם בא יבא AND IF [THE PRIEST] SHALL COME IN at the end of the second week,

וטהר הכהן את הבית, “the priest purifies the house.” He does so by means of a verbal declaration.

וראה והנה לא פשה AND LOOK UPON IT, AND, BEHOLD, THE PLAGUE HATH NOT SPREAD … [THEN THE PRIEST SHALL PRONOUNCE THE HOUSE CLEAN].— This verse, as shown above, is intended to teach the law regarding the case that it (the plague) has stayed as it was during both the first week and the second week. What shall he do to it? One might think that he shall pronounce it clean just as the verse literally implies: וטהר הכהן את הבית "and the priest shall pronounce the house clean"! It, however, states, "[The priest shall declare the house clean] כי נרפא הנגע if the plague is healed" — Scripture says, as it were, I pronounce clean only that plague which is healed, and only that house is healed which has been scraped and re-plastered and in which the plague has not recurred, but this, in which during two weeks the plague has remained in the same condition, is not yet healed and thus not yet clean, and requires removal of the stones, scraping and re-plastering and yet a third week. And the verse is accordingly to be explained as follows: ואם בא יבא, And if having come once he comes again at the end of the second week and he looks upon it, and, behold, it has not spread, he shall re-plaster it and of course also remove the stones and scrape it — for re-plastering never takes place without removal of the stones and scraping (and Scripture merely states אחרי הטוח for the sake of brevity) — אחרי הטוח את הבית and after the house has been re-plastered, וטהר הכהן את הבית, shall the priest pronounce clean, if the plague has not returned at the end of the third week, כי נרפא הנגע FOR THEN THE PLAGUE IS HEALED. If, however, it has returned at the end of that week it is unnecessary to state the law here since it has already explained regarding a recurring plague that it requires the demolition of the house (cf. Rashi on v. 44).
