(Mishnah): We put the Eruv in the old house.

(R. Avin): Our Mishnah discusses an old resident. (If we will switch houses, people will say that it is because he was taking it for himself. If the old resident went away, there is no concern.)

(Mishnah): The pit closest to the [source of] irrigation channel fills first.

Limitation: This is when the irrigation channel passes over [the pit, but not if they need to dam it to divert the water to their pit].

(Shmuel): It is even if [the pit] is to the side [of the channel.

There (in Bavel) they say that if [a pit] far from [the source] and it is easy to fill it [from the channel, for it is close to it] has precedence over if [a pit] close to [the source] and it is hard to fill it [it is far from the channel].

According to Rabanan there (in Bavel), it is fine (a Mishnah in Ma'aser Sheni (4:3) says that one can redeem Ma'aser Sheni through an Amah Ivriyah, even though she is a minor);

There (in Bavel) they say in the name of Rav Nachman bar Yakov, any [minor] that they give to him a nut and he throws it away; if they give to him a stone, he takes it (he has no Da'as) - what one finds in his hand is [Hefker] like what one finds in a wasteheap;

If they give to him a nut and he takes it; if they give to him a stone, and he throws it away - Gezeilo (stealing his Metzi'ah) is considered theft for the sake of Shalom.

If they give to him a nut, and he hides it away, and brings it (when one requests it) afterwards, Gezeilo is absolute theft. He can acquire for himself, but he cannot acquire for others.

(Rav Huna): Just like he can acquire for himself, he can acquire for others.

All agree that his gift is not a gift, for it says "Ki Yiten Ish" - the gift of an Ish (adult) is a gift, but the gift of a minor is not a gift.

(R. Yudah bar Pazi citing R. Yochanan): According to Chachamim [in our Mishnah], Gezeilo is not theft, unless he brought two hairs.

(R. Avahu citing R. Yochanan): [R. Yosi says that Gezeilo is absolute theft] for Beis Din to take it from [the Gazlan, and return it to the minor], but for Korban and Shevu'ah, all agree that it is [proper theft] only if he brought two hairs.

Question: However, according to Rabanan here (in Eretz Yisrael), R. Yosi asked, if so ("Ki Yiten Ish" teaches that a minor's gift is not a gift), he cannot acquire even for himself), for it says "Ki Yiten Ish El Re'ehu" - [to acquire, the recipient] must [also] be [an adult,] like his colleague! (If so, how can an Amah Ivriyah redeem Ma'aser Sheni?)

Answer (R. Yosi bei R. Bun citing R. Shmuel bar Rav Yitzchak): The case is, they are Pa'utos, like our Mishnah said, that Pa'utos, their purchase is a purchase, and their sale is a sale, in Metaltelim.

Question (Mishnah): One cannot be Mezakeh (make the people of his Chatzer partners in the Eruv) through his minor son or daughter, or through his Eved Kena'ani or Shifchah Kena'anis, for their Yad is like his Yad (whatever they acquire becomes his. Eruv is mid'Rabanan. This shows that even mid'Rabanan, they cannot acquire for others, unlike Rav Huna!)

Answer (Rabanan of Kisarin): Here (Rav Huna) discusses a minor with Da'as. Here (the Mishnah) discusses a minor without Da'as. (We explained this like PNEI MOSHE.)
