(Mishnah): If a Nochri gave to a Yisrael a dough to make for him, it is exempt from Chalah;

If he gave to him a gift - [if he gave it] before kneading, it is obligated. After kneading, it is exempt.

One who makes a dough with a Nochri - if there is not in the Yisrael's portion the Shi'ur of Chalah, it is exempt from Chalah.

If a Nochri converted and he had a dough - if he made it before he converted, it is exempt; after he converted, it is obligated.

If it is a Safek, it is obligated, and [a Zar who ate it b'Shogeg] is not liable a Chomesh.

R. Akiva says, it all depends on [when] it formed a crust in the oven.

(Gemara) Question: What is the difference between [one who makes a dough with a Nochri] and a dough [subject to the law] of Arnona (the Nochri king takes a 10th)? Perhaps it is not obligated in Chalah [if there is not a Shi'ur of Chalah in the Yisrael's portion]?!

Answer: There (Isas Arnona), it is in the Yisrael's Reshus. Perhaps the Nochri will reconsider and not take it (rather, he will take money). However, here (partnership), does it depends on [the Nochri's] intent?! (Surely he will take the portion that belongs to him! We explained this like GRA.)

(Beraisa - R. Yehudah): If Malai (merchandise given to be sold in a store) is of a Yisrael and Nochri workers [knead and] make [bread] inside (the store), it is obligated in Chalah. Malai of a Nochri and Yisrael workers make inside, it is exempt from Chalah. (We explained this like OHR ZARU'A 235.)

Support (R. Yosi - Mishnah): If a Nochri gave to a Yisrael a dough to make for him, it is exempt from Chalah.

Question (R. Bun bar Chiyah, to R. Ze'ira): Even if there is in the Yisrael's portion the Shi'ur of Chalah, [it should be exempt]! It should be as if there is a Kav [of the Yisrael] here (on one side), and a Kav [of the Yisrael] here (on the other side), a Kav of the Nochri in the middle! (When something exempt is in the middle, it blocks the sides from joining.)

Answer (R. Ze'ira): Is it not mixed through Girus (i.e. Irus, i.e. it is all kneaded together?! We explained this like RI BEN MALKITZEDEK.)

(Mishnah): If a Nochri converted and he had a cow - if it was slaughtered before he converted, he is exempt [from giving Matanos to a Kohen]. If [Shechitah was] after he converted, he is obligated. If it is a Safek, ha'Motzi me'Chavero Alav ha'Re'ayah (to collect, one must bring a proof. The Kohen cannot, so the convert is exempt.)

Question: There you say that a Safek is exempt, and here you say that a Safek is obligated!

Answer (R. Acha): I asked R. Ami, and he told me 'who will tell me that he does not take money from the Shevet?!' (He must separate Chalah due to Safek Isur, but he need not give it to Kohanim for free. We explained this like GRA.)

(R. Yakov bar Zavdi citing R. Chiya citing R. Lazar): He takes money from the Shevet.

Question: [Also] there, he should separate [Matanos], and take money from the Shevet!

Answer (R. Yosi): Chalah is Tevel (forbidden to eat before it is separated), and it is an Aveirah of Misah (bi'Ydei Shamayim), so he must separate.

Question: [If so,] he should not take money from the Shevet!

Answer: [He takes,] due to ha'Motzi me'Chavero Alav ha'Re'ayah.

(R. Bun bar Chiyah): If two Nochrim made [a dough of] two Kavin and divided it (before they converted), and each added to his share, they are obligated [in Chalah], for they did not have a time of obligation and they were exempt [then].

If two Yisraelim made two Kavin and divided it, and each added to his share, they are exempt, for they had a time of obligation and they were exempt. (ARUCH HA'SHULCHAN YD 326:13 - they joined flour with intent to make a joint dough, which is obligated. Once they added water, before kneading, they decided to divide, and be exempt.)

Question: If a Yisrael and a Nochri made two Kavin and divided it (and the Nochri converted) and each added to his share, granted, the Yisrael's share is obligated (it did not have a time of obligation and an exemption). What is the law of the Nochri's share?

Answer: The Yisrael's share is obligated only due to the Nochri's share. Is the Yisrael's share obligated and the Nochri's share is exempt?! (Surely also the Nochri's share is obligated! - RA'AVAD Hilchos Bikurim 7:10, GRA.)
