(Mishnah): One may be Me'arev with Demai (doubtfully tithed produce), Ma'aser Rishon from which Terumah was taken, or Ma'aser Sheni or Hekdesh that was redeemed;

Kohanim may be Me'arev with Chalah [or Terumah];

One may not be Me'arev with Tevel, Ma'aser Rishon from which Terumah was not taken, or Ma'aser Sheni or Hekdesh that was not redeemed.

If Reuven sent an Eruv with any of the following, it is invalid: a deaf person, lunatic, or minor, or with one who does not acknowledge [the enactment of] Eruvin;

If he told Shimon [a healthy adult] to receive the Eruv from him [and be Me'arev, i.e. place it for an Eruv], it is valid.

(Gemara) Question (R. Yakov of the south): Is our Mishnah unlike Beis Shamai? A Mishnah teaches that [an Esrog] of Demai, Beis Shamai disqualify [for it is not considered his. Also regarding Eruv, it is not proper for him to eat.] Beis Hillel are Machshir [for he could make his property Hefker, and become an Oni, and then he is permitted Demai]. Of Ma'aser Sheni in Yerushalayim, one may not take it [for the Mitzvah]. If he took it, it is Kosher.

(Rav Sheshes citing R. Chiyah Ruba): Tevel about which he stipulated [before Shabbos, that the tithes he will separate later should take effect now], one may move it [on Shabbos];

How does he do (to eat it on Shabbos)? He puts his eyes on part (that the tithes will be from there) and eats the rest.

(Beraisa - Beis Shamai): One may not be Me'arev with Ma'aser Sheni in Yerushalayim.

(R. Yirmeyah): This refers to Eruvei Chatzeros. (They hold that Eruvei Chatzeros requires Kinyan. This is like business with Ma'aser Sheni, which is considered Hash-m's property);

However, Eruvei Techumim are permitted, i.e. if a resident of [another] city put his Eruv in Yerushalayim. He can ascend and eat it there. (It cannot help for a resident of Yerushalayim, for it must be put outside the city, and one may not take it or eat it outside Yerushalayim.)

(Shmuel): If a child is about nine or 10 [years old, this is Pe'utos. Mid'Rabanan he can acquire, so] his Eruv is an Eruv.

(R. Yosah): This refers to Eruvei Techumim [which require a proper Kinyan], but Eruvei Chatzeros [is mere partnership], even a [smaller] minor [can be Me'arev].

(R. Yehoshua): Why do we make Eruvei Chatzeros [if we already have Shituf in the Mavuy]? It is due to Darchei Shalom;

A case occurred in which a woman hated another woman. She sent her Eruv through her son, and [the other one] took him, hugged him and kissed him. He came and told his mother;

She said "so she loves me, and I did not know!'' Amidst this, they made Shalom. About this it says 'Deracheha Darchei No'am v'Chol Nesivoseha Shalom.''

If Reuven sent an Eruv with a deaf person, lunatic, or minor... [if he told a healthy adult to receive it from him and be Me'arev, it is valid].

(R. Elazar): [The sender] must stand with him [and see that the recipient gets it].

Question: There (in Ma'aser Sheni), R. Yosah cited Rav Sheshes, and R. Eliezer bar Yosi cited R. Avun, that if one said to his friend "I tithe [your Peros] for you'', he need not stand with him. And here, you say so [that he must stand with him]?!

Answer #1 (R. Chiyah bar Rav Ada bar Ahavah): There we discuss an adult, and here we discuss a minor.

Answer #2 (R. Acha citing R. Chinena): We can even say that in both cases we discuss an adult, or in both cases we discuss a minor. There he said "I tithe for you''; he need not stand with him. a minor. However, here he said "be Me'arev for me.'' (The Shali'ach did not volunteer by himself to be a Shali'ach.)

We learn this (Eruv) from that (Ma'aser), and that (Ma'aser) from this (Eruv);

We learn this from that, that if he said "I are Me'arev for you''; he need not stand with him;

We learn that from this, that if he said "tithe for me''; he must stand with him.
