(Mishnah): One may make an Eruv and be Mishtatef [in a Mavoy] with any [food] except for water and salt;

Any [food] may be bought with money of Ma'aser Sheni, except for water and salt;

If one vowed not to eat Mazon, he is permitted [only] water and salt.

One may be Me'arev on behalf of a Nazir with wine, and on behalf of a Yisrael with Terumah;

Sumchus says, one must be Me'arev with Chulin [for a Yisrael].

One may be Me'arev on behalf of a Kohen in a Beis ha'Pras (a field in which a grave was plowed. Mid'Rabanan, it is forbidden to Kohanim like a cemetery. One who walks through is deemed Tamei, lest he move a bone, unless he crouches down and blows the earth before each step to reveal bones that might be there.)

R. Yehudah says, one may be Me'arev for a Kohen even in a cemetery, because he could shield from Tum'as Ohel [in a box or coach], enter and eat it.

(Gemara - R. Acha): [Our Mishnah] is like R. Eliezer;

A Mishnah there teaches that one may be Me'arev or Mishtatef with any food, except for water and salt. R. Eliezer says so. (R. Yehoshua says that an Eruv is only a loaf.)

(R. Yosah): It is like everyone. [When it says only] "Me'arvin'' (e.g. in our Mishnah) this refers only to Chatzeros. [When it says "Me'arvin] and Mishtatfin'' (e.g. in that Mishnah), it can refer to Chatzeros or Techumim. (There R. Yehoshua teaches only about Eruvei Techumim. He can agree about Eruvei Chatzeros. We explained this like PNEI MOSHE.)

Our Mishnah is unlike R. Meir;

(Beraisa): Anything eaten raw, as it is (by itself), one may be Me'arev with it. [What is eaten only] with bread, one may not be Me'arev with it. R. Meir says so;

Garlic and onions, according to R. Meir one may not be Me'arev with them.

(Beraisa - R. Shimon ben Elazar): A case occurred in which R. Meir spent Shabbos in Ardaskam, and one came and told him "I was Me'arev with onions'', and R. Meir sat him in his four Amos (since his Eruv was invalid, he left his Techum and therefore lost his Techum).

Even though R. Meir said that one may make an Eruv and be Mishtatef with any food except for water and salt, this is only if it is eaten raw, as it is (by itself). Luf and Kulakas (kinds of onions), according to R. Meir one may not be Me'arev with them. According to Rabanan, one may be Me'arev with them. (We explained this like SHA'AREI TORAS ERETZ YISRAEL.)

Two Klalim (general rules) were said, and they do not resemble each other. One may make an Eruv and be Mishtatef with anything except for water and salt, as long as it is eaten raw, by itself.

[The other Klal is,] one may buy anything with Kesef Ma'aser, except for water and salt, whether something that is eaten raw by itself, or something that is not eaten raw by itself.

One may make an Eruv and be Mishtatef with anything except for water and salt - this is both according to R. Akiva, and according to R. Yishmael. One may buy anything with Kesef Ma'aser except for water and salt. This is like R. Akiva;

However, according to R. Yishmael [it is not true]. R. Yishmael taught "v'Nasata ha'Kesef b'Chol Asher Te'aveh Nafshecha'' is a Klal. "Ba'Bakar uv'Tzon uv'Yayin uv'Shechar'' is a Prat. "Uv'Chol Asher Tish'alcha Nafshecha'' is another Klal. From a Klal u'Ferat u'Chlal you learn only like the Prat;

Just like the Prat is explicit, Vlad (a child or Peros) and Vlados (matters created from) the ground, so I include only Vlad and Vlados ha'Aretz.

R. Akiva explains, just like the Prat is explicit, Pri, Vlad Pri and Machshirei Pri, so I include only Pri, Vlad Pri and Machshirei Pri.

What do they argue about? They argue about fish, birds and mushrooms (they were not created from the ground). According to R. Akiva one may buy them with them Kesef Ma'aser, and according to R. Akiva one may not buy them.

One may make an Eruv and be Mishtatef with anything except for water and salt.

(R. Yosah): [Water and salt are invalid] because the body is not sustained through them.

(R. Levi): It is because they are species of a curse (the flood, or Sedom).
