(Mishnah): If one vowed from milk, Kum (this will be explained) is permitted; R. Yosi forbids.

If he vowed from Kum, milk is permitted.

Aba Sha'ul says, if one vowed from cheese, he is forbidden both salted and unsalted cheese.

(Gemara): What is Kum? It is liquid that separates from the cheese (i.e. the hardened milk).

Question: What is R. Yosi's reason?

Answer: [Kum] is called by the name of its source (Kum of milk).

Consequence: According to R. Yosi, one who vows from wine is forbidden cooked wine [for it is still called wine].

This is a general rule that R. Shimon used to say in the name of R. Yehoshua - any Davar she'Yesh Lo Matirin (it can become permitted), e.g. Tevel (it can be tithed), Ma'aser Sheni, Hekdesh (they can be redeemed; Ma'aser Sheni is permitted in Yerushalayim even without Pidyon), and Chadash (it is permitted after the Omer is offered), Chachamim did not give a Shi'ur [for Bitul]. Rather, Min b'Mino, any amount is forbidden. Min b'Eino Mino, if it gives taste [it forbids];

And any Davar she'Ein Lo Matirin (it cannot become permitted), e.g. Terumah, Chalah, Orlah and Kil'ai ha'Kerem, Chachamim gave a Shi'ur. Min b'Mino, Terumah and Chalah [are Batel] in 100 parts [of Chulin], and Orlah and Kil'ai ha'Kerem in 200. Min b'Eino Mino, if it gives taste.

Question: These vows, how do you consider them - like Davar she'Yesh Lo Matirin, or Davar she'Ein Lo Matirin?

Answer: Is it reasonable to consider them like Davar she'Yesh Lo Matirin?! A Beraisa teaches that a Chacham uproots a Neder retroactively! (It is as if there was never a vow. There is no Isur that was permitted!)

Rebuttal: He uproots only from now and onwards. (Until now he was forbidden, so it is considered Davar she'Yesh Lo Matirin. We explained this like the ROSH.)

Question #1: A Beraisa considers them like Davar she'Ein Lo Matirin!

(Mishnah): Gidulei Terumah (what grow from Terumah that was planted) is Terumah, and Gidulei Gidulin (what grow from Gidulei Terumah) are Chulin. However, Tevel, Shevi'is, Terumos of Chutz la'Aretz, Meduma (a mixture of Terumah and Chulin) and Bikurim, their Gidulim are Chulin;

Gidulei Hekdesh and Ma'aser Sheni are Chulin, and he redeems them [based on the value] at the time he planted them (even though he could ask to permit his Hekdesh, it is Batel, like Davar she'Ein Lo Matirin. The same applies to Nedarim.)

And [a Beraisa] taught about this, when is this? It is for a matter in which the seed perishes, but for a matter in which the seed does not perish (e.g. an onion just gets bigger, even) Gidulei Gidulin are forbidden. (This implies that when the seed perishes, it is Batel, for it is Davar she'Ein Lo Matirin.)

And there is [another] stringency of Gidulin, for R. Ze'ira, citing R. Yonason, said that if an onion of Kil'ai ha'Kerem was uprooted and planted, even if it increased much [than the Isur], it is forbidden, for Gidulin of [a root of] Isur are not Mevatel [the root of] Isur. (We explained this like PNEI MOSHE.)

Contradiction: A Mishnah considers it like Davar she'Yesh Lo Matirin!

(Mishnah): If one vowed from a matter, and it became mixed with something else - if it gives taste, it is forbidden. (If not, it is permitted.)

Rebuttal: [Nedarim are Davar she'Yesh Lo Matirin, but] Min b'Eino Mino is [Batel if it does not give taste,] like Davar she'Ein Lo Matirin. (We explained this like the RASHBA.)

(Mishnah): If one vowed from meat, he may have gravy and Kipah (tiny pieces of meat at the bottom of the pot);

R. Yehudah forbids.

R. Yehudah: A case occurred, and R. Tarfon forbade eggs cooked with the meat!

Chachamim: And so it was! When is this? It is when he said 'this meat is Alai', for one who vowed from a food and it became mixed with other food, if the forbidden food can be tasted, the mixture is forbidden. (We explained this like RASHBA, RAN.)

If one vowed from wine, he is permitted a Tavshil containing wine;

If he said 'Konam this wine, I will not taste it' and it fell into a Tavshil, if the wine can be tasted, it is forbidden.

(Gemara - R. Heila): Since he said 'this', he forbade it and Hana'ah from it.

(Mishnah): If one vowed from grapes, he is permitted wine. If one vowed from olives, he is permitted [olive] oil;

If he said 'I will not taste these grapes or olives', he is forbidden them, and what comes from them.

(Gemara - Beraisa - R. Shimon ben Elazar): [Also regarding] Konam - anything that it is normal to eat it, and it is normal to eat what comes from it, if he vowed [from] it, he is permitted what comes from it. If he vowed [from] what comes from it, he is permitted it. (PNEI MOSHE)

What is this [that it is normal to eat it, and what comes from it]? E.g. olives and grapes.

And anything that it is normal to eat it, and it is not normal to eat what comes from it, if he vowed [from] it, he is permitted what comes from it. If he vowed [from] what comes from it, he is forbidden it. (We explained this like MEICHAL HA'MAYIM.)

What is this [that it is normal to eat it, but not what comes from it]? E.g. strawberries.

And anything that it is not normal to eat it, but it is normal to eat what comes from it, if he vowed [from] it, he intended only for what comes from it.

Question: What is this [that it is not normal to eat it, but it is normal to eat what comes from it]?

Answer (R. Yosi bei R. Bun): It is garden seeds that are not normally eaten (one eats what grow from them).
