(Mishnah): Fig rings become obligated when they are smoothed (with juice). One may smooth with figs and grapes of Tevel. R. Yehuda prohibits it.

If one smooths (a fig ring) with grapes, the fig ring doesn't now contract Tumah. R. Yehuda says that it does. Dried figs - are obligated after they've been pressed. And figs stored in a bin - after they've been pressed into a ring.

When some of the figs had already been pressed and the barrel broke, or if some of the figs had already been pressed into a bin and the bin was opened, he may not snack on them (as they've already become obligated). R. Yosi permits them.

(Gemara) (R. Chananya, son of R. Yasa): R. Yehuda and Rabbanan disagree over Rabbinic Tevel (which will be discussed later on in Perek 4 Mishnah 1), but as for Tevel of the Torah (where it's completed and it has been brought into the house), even the Rabbanan agree.

R. Mana himself taught and R. Avin taught from R. Yochanan the reasoning of R. Yehuda and Rabbanan, as the Tosefta taught - If one cracks olives with Tamei hands (in order to soften them), the olive oil is able to cause things to contract Tumah.

If he cracks them (to soften them) to allow them to absorb salt, they do not become liquids etc.

If he cracks them to check if they are moist inside, they do not become liquids that can cause things to contract Tumah. R. Yehuda says that they do become liquids etc.

Rabbanan say that he checks if the fruit is ripe by feeling the olive. R. Yehuda says that he checks by squeezing the olive to see if it has juices.

Here (in our Mishnah), the Rabbanan say that he rubs the figs with the body of the grapes (rather than using its juices). R. Yudah says that he smooths with its juices.

(Rebbi to his son R. Shimon): Go up and bring us dates from the barrel.

(R. Shimon): Aren't they Muktzeh?

(Rebbi): Haven't you learned yet that only figs and grapes (drying on the roof) are Muktzeh?

(R. Shmuel bar Sisretai): It's because they are disgusting in the interim.

Question (R. Zeira to R. Yasa): Surely R. Shimon reasons that figs drying on the roof are not Muktzeh and it must have been unripe figs that are cracked in half and placed on the roof that he said are Muktzeh...?

Answer (R. Yasa to R. Zeira): I agree.

R. Yosi bei R. Bun and R. Yitzchak bar Bisna citing R. Yochanan also said this.

...And Rebbi replied to R. Shimon that only figs and grapes (drying on the roof) are Muktzeh?

(R. Yaakov bar Zavdi citing R. Abahu): This was said concerning Shabbos laws, but concerning Ma'asros, all fruits are not obligated until they are dried out.

(Rebbi): The Mishnah also supports this - the obligation comes when dried figs have been pressed and figs stored in a bin have been pressed into a ring (rather than when they are still drying).

(R. Yochanan): The first Tana's reasoning that if the bin was opened, he may not snack on them, is because the upper figs cannot be pressed without the lower ones first being pressed. However, the opposite is not true. The latter opinion (R. Yosi) says that even the lower ones still need the upper ones, so they are not yet completed and he may still snack on them.

(R. Elazar): The first Tana is R. Meir.

(Why did he say this?) So that you shouldn't say that it's an unspecified author; and when a Mishnah with an unspecified author (known as a Stam Mishnah) disagrees with R. Yosi, the Halacha follows the Stam. Therefore, R. Meir was named, as the rule is that when R. Yosi and R. Meir disagree, the Halacha follows R. Yosi.
