— Because we learnt: He who carries out from one domain to another domain [on the Sabbath] is guilty. And are we not concerned there also with bringing in, and yet he calls it hoza'ah.? [No!] Perhaps [the Tanna means] carrying out from a private domain to a public domain. — If so, let him say distinctly: He who carries out from a private domain to a public domain [is guilty]; why does he say: ‘from one domain to another domain’? Obviously, to include even bringing in from a public domain to a private domain; and he calls it hoza'ah — What is the reason? — The withdrawing of an object from its place the Tanna calls hoza'ah. Rabina said: The Mishnah also lends support to this view, for it states: The laws of carrying [Yezi'oth] on the Sabbath are two, subdivided into four inside; and two, subdivided into four outside: and it goes on to explain haknasah [bringing in]! This is conclusive. Raba said: The Tanna means domains; there are two kinds of domain with regard to carrying on the Sabbath. THE SHADES OF LEPROUS AFFECTIONS ARE TWO, SUBDIVIDED INTO FOUR. We learnt there: the shades of leprous affections are two, subdivided into four: Bahereth intensively white, like snow; secondary to it [i.e., its derivative], Sid ha-hekal; Se'eth like white wool; secondary to it, Kerum bezah. R. Hanina said: the Tanna who stated this Mishnah of leprous affections is not R. Akiba; for, if it were R. Akiba, then, since elsewhere he enumerates them one above the other, Sid hekal cannot combine with any other shade; for, with which shade will you combine it? Will you combine it with Bahereth? There is Se'eth which is [one degree] higher than it [intervening, Bahereth being two degrees higher]. Will you combine it with Se'eth.? It is not its derivative. If so, Kerum bezah also — with what will you combine it? Will you combine it with Se'eth? There is Sid which is [one degree] higher than it [intervening, Se'eth being two degrees higher]. Will you combine it with Sid? It is not of its kind.8ᵃᵇᶜᵈᵉᶠᵍʰ
