Bitter vetch of maaser sheni is eaten as shoots, and it may enter Jerusalem and leave. [If] it became tamei, R' Tarfon says: It is distributed into doughs; but the Sages say: It is redeemed. And [bitter vetch] of terumah, Beis Shammai say: We soak and pound it in taharah, but feed it in tumah. But Beis Hillel say: We soak it in taharah, but we pound and feed it in tumah. Shammai says: It is eaten dry. R' Akiva says: Everything done with it is [done] in tumah.

Coins of chullin and coins of maaser sheni that became scattered, what he gathered, he gathered for maaser sheni until he completes [the total], and the rest is chullin. If [they fell in] a jumble and he scooped up handfuls, it is reckoned proportionately. This is the rule: What is picked up [one at a time goes] to maaser sheni, and what is jumbled is reckoned proportionately.

[If] a sela of maaser sheni and of chullin became mixed together, he brings a sela's worth of coins, and says: “The sela of maaser sheni, wherever it is, is deconsecrated on these coins,” and he selects the nicer in it and redeems them on it, for they said: One may deconsecrate silver on copper in exigencies, but not to retain it in this way; rather, he deconsecrates them again on silver.

Beis Shammai say: A person may not change his sela coins into gold dinars. But Beis Hillel permit it. R' Akiva said: I made, for Rabban Gamliel and for R' Yehoshua, their silver into gold dinars.

[If] one converts coins of maaser sheni into a sela, Beis Shammai say: Coins [for] an entire sela. But Beis Hillel say: A shekel's worth [of the copper into] silver and a shekel's worth [as] coins. R' Meir says: We may not deconsecrate silver and produce onto silver, but the Sages permit [this].

[If] one changes a sela of maaser sheni in Jerusalem [into copper coins], Beis Shammai say: Coins for the entire sela. But Beis Hillel say: A shekel [of the sela in] silver and a shekel [in] coins. Those who debate before the Sages say: For three dinars [of the sela] silver and for [the remaining] dinar coins. R' Akiva says: Three dinars [of the sela] silver and the fourth [dinar] coins. R' Tarfon says: [For the fourth dinar he takes] four aspers of silver. Shammai says: He should leave it in the store and eat against it.

One whose children, some were tamei and some were tahor, he sets down the sela coin and says: “What the tahor ones drink, this sela coin is deconsecrated upon that”; thus, the tahor ones and the tamei ones both drink from the same vessel.

A person should not say to his friend: “Bring up for me these fruits to Jerusalem, to divide”; rather, he says to him: “Bring them up for us to eat them and drink them [together] in Jerusalem.” But they may give to one another [as] a free gift.

One may not purchase terumah with money of maaser sheni, because he lessens its consumption. But R' Shimon permits. Said to them R' Shimon: If He was lenient with respect to shelamim offerings which leads to [prohibitions of] pigul, nosar, or tamei, shall we not be lenient with respect to terumah? They said to him: If He was lenient with respect to shelamim offerings which are permitted to non-Kohanim, shall we be lenient with respect to terumah, which is forbidden to non-Kohanim?

[If] someone had coins in Jerusalem and he needs them, and his friend has produce, he says to his friend: “These coins are hereby deconsecrated upon your produce.” It thus comes about that one eats his produce in taharah, while the other one makes use of his coins. But one should not say this to an am haaretz, except with demai.

Produce in Jerusalem and coins in the province, he says: “Those coins are hereby deconsecrated upon this produce.” Coins in Jerusalem and fruits in the province, he says: “These coins are hereby deconsecrated upon that produce,” provided that the fruits are brought up and eaten in Jerusalem.

Coins enter Jerusalem and leave; produce enters but may not leave. Rabban Shimon ben Gamliel says: Even produce enters and leaves.

Produce, the processing of which has been finished, that then passed through Jerusalem, its maaser sheni must be returned and eaten in Jerusalem. And [produce], the processing of which has not yet been finished: baskets of grapes for the winepress or baskets of figs for the drying area, Beis Shammai say: Its maaser sheni must be returned and eaten in Jerusalem. But Beis Hillel say: It may be redeemed and eaten any place. R' Shimon ben Yehudah says in the name of R' Yose: Beis Shammai and Beis Hillel did not disagree over produce, the processing of which was not finished, that its maaser sheni may be redeemed and eaten any place. Over what did they disagree? Over produce, the processing of which was finished, for Beis Shammai say: Its maaser sheni must be returned and eaten in Jerusalem. But Beis Hillel say: It may be redeemed and eaten any place. And demai may enter and leave and be redeemed.

A tree that stands inside but [its foliage] extends outside, or it stands outside but [its foliage] extends inside: from the wall and inwards is [treated] like inside; from the wall and outwards is [treated] like outside. Olive presses whose entrances are to the inside but whose interior is to the outside, or whose entrances are to the outside but whose interiors are to the inside, Beis Shammai say: It is all [treated] like inwards. But Beis Hillel say: From the wall and inwards is [treated] like inside; from the wall and outwards is [treated] like outside.
