(Mishnah) (R. Yehuda): One who thins out vines (to allow improved growth of grapes) - he may thin out what belongs to the poor just as he does for his own.

(R. Meir): He may only thin out his own but not what belongs to the poor.

(Gemara): All agree that if one sold 10 clusters to his friend, he may not touch them. All agree about a partner, that just as one may thin out that which is his, he may thin out that which is his partner's.

R. Yehuda (above) viewed a poor man like a partner; R. Meir viewed him like a buyer (so the owner - 'the seller' - cannot touch the poor man's produce).

(R. Ami): (How could the poor be like partners?) If the Olelos were eaten by a wild animal, if they are like partners, the owner would have to replace the Olelos!

Question (R. Yochanan): It seems that the opinion of R. Yehuda has switched - earlier (in Perek 5 Mishnah 3 - Zevachim 52-1(c)-(d) - this question is also asked there) he said that (if one who waters his field before the poor passed through it,) either way, the owner should collect the Leket and place it on the fence and the poor should come and take it (to prevent a loss for the poor). But here R. Yehuda said that one may also thin out what belongs to the poor?

Answer: It is different here - since he is pressing them and thinning them out, they will produce more the following year, so it is beneficial for the poor.

Question: This should also apply to one who waters his field, since it will be beneficial to the poor the following year?

Answer: There, since the custom is to plant seeds one year and vegetables the next year, we are concerned that he will plant vegetables the following year, that are exempt from Peah, and cause a loss to the poor.

(Mishnah): Kerem Revay (fruits of the fourth year of a vine, that are holy and must be taken to Yerushalayim, similar to Maaser Sheni produce. For other trees, this status is known as Netah Revay) - Beis Shammai says that one does not add a fifth when it is redeemed and it does not need to be removed (Biur) in the fourth and seventh years of the Shemittah cycle. Beis Hillel requires these two things.

(Beis Shammai): Peret and Olelos apply to it and the poor redeem it for themselves.

(Beis Hillel): All of it goes to the winepress (and it is then taken to Yerushalayim).

(Gemara) (Baraisa): Rebbi says that Beis Shammai only said this about Shevi'is, but in all other years, Beis Shammai says that one must add a fifth and the law of Biur applies.

According to Rebbi, Beis Shammai also learned Netah Revay from Maaser Sheni - just as there is no obligation of Maaser Sheni in Sheviis, so there is no obligation of (the redemption and adding a fifth to) Netah Revay in Sheviis.

Question: If it is learned from Maaser Sheni in Sheviis, Netah Revay should not apply at all in Sheviis and it should not require redemption or to be eaten in Yerushalayim?

Answer: Only adding a fifth and Biur are learned from Maaser Sheni, but the other laws are learned from its own pasuk, as the pasuk states (Vayikra 19:24), "(In the fourth year, all its fruit) shall be sanctified to praise Hashem'' - they are like Bikurim, that a declaration of praise to Hash-m is said over them.

Question: Even though an Onen (a person whose close relative was buried that day) may not eat Netah Revay, he should be permitted it in Sheviis - since Netah Revay is learned from Maaser Sheni, when Maaser Sheni does not apply, this prohibition should not apply...?

Answer: The Torah says 'shall be sanctified' - to teach that it is prohibited to an Onen like sacrifices.

Question: Since it is learned from Bikurim, it should be obligated in Biur in Sheviis?

Answer: Beis Shammai agree with R. Shimon that Bikurim are exempt from Biur.

Question: In Sheviis, one should be able to redeem it with things attached to the ground (since the prohibition to do this was learned from Maaser Sheni, which does not apply in Sheviis)? (This question remains unanswered.)

Baraisa (R. Shimon ben Gamliel): (Disagreeing with Rebbi above (c) & (d)) Both in Sheviis and in other years, Beis Shammai says that Netah Revay is exempt from adding a fifth and from Biur.

(The Gemara now asks and responds to all of the questions that were asked to Rebbi about Sheviis, but here they are questioning the view of R. Shimon ben Gamliel.) According to R. Shimon ben Gamliel, they did not learn Netah Revay from Maaser Sheni at all. If so, Netah Revay should not apply at all in Sheviis and it should not require redemption or to be eaten in Yerushalayim?

Answer: Its laws are learned from its own pasuk, as the pasuk states (Vayikra 19:24), "(In the fourth year, all its fruit) shall be sanctified to praise Hashem'' - they are like Bikurim, that a declaration of praise to Hash-m is said over them.

Question: It should be permitted to an Onen?

Answer: The Torah says 'shall be sanctified' - to teach that it is prohibited to an Onen like sacrifices.

Question: Since it is learned from Bikurim, it should be obligated in Biur in Sheviis?

Answer: Beis Shammai agree with R. Shimon that Bikurim are exempt from Biur.

Question: One should be able to redeem it with things attached to the ground? (This question remains unanswered.)
