What is sourdough? Something that leavens other things. And what is leavened? Something that has been leavened by other things. From when is it called sourdough? As soon as it become unsuitable as dog food. One must not cover blood with ashes which burned [and thus created] during the holiday, because it does not count as something "prepared [before the holiday]". If one brought dust to plaster his roof, lime to whitewash his house, one uses it to cover. Rabbi Yose says: you can on a holiday not slaughter a koi because it is a doubt, and if one has slaughtered him, one does not cover his blood.

There is a stringency with Terumah (the priestly portion of produce) that there is not with second tithe (which is exchanged for money and brought to Jerusalem) or first fruits, and [a stringency] with second tithe that there is not with Terumah. [With respect to the stringency of Terumah], we may not take [Terumah] except out of a mass [of produce] in close proximity (המוקף), nor may we take it except from [produce that is in] a finished state, nor may we take it except from the pure on behalf of the impure, or the medumma (a forbidden mixture of Terumah and chullin), and we are liable on it for an extra fifth, and it applies to all [species of] produce, which is not the case with first fruits. And it applies to all the years [of the seven-year agricultural cycle other than the seventh year], all of which is not the case with second tithe [which only applies to the first, second, fourth, and fifth years].

And so too Rabbi Shimon would say, [the Sages] did not state that produce that grows from [the seeds of] first fruits must be eaten in Jerusalem. "Tithes" -- about which "tithes" did they speak [when the Sages ruled that aftergrowths must be treated as tithes (see Ter. 9:6)]? [They ruled that aftergrowths are treated as tithes only] with regards to anything whose seed disintegrates [after planting], with regards to [produce] that is taken in and out of Jerusalem, with regards to [produce] that does not have the value of a perutah, and with regards to [produce] that is not [subject to the laws of] redemption. Rabbi Shimon ben Yehuda says in the name of Rabbi Shimon, one is not liable [to bring] first fruits that are attached to the ground.

A k'vi (see Bikkurim 2:8) -- how is it like a wild animal? Its blood requires covering like a wild animal. Rabbi Eliezer says, they are liable to bring a variable guilt-offering for [partaking in] their [forbidden] fats. How is it like both a wild animal and a domesticated animal? One who flays (המפשיט not מפסיד, see GR"A) it, [the laws regarding whether its hide is] connected [to its flesh is] like wild animals and domesticated animals (see Tos. Chullin 8:6). And [the laws of] the sciatic nerve apply to it, like they do to wild animals and domesticated animals. If he said, "Behold, I will become a nazirite if [the k'vi] is [neither] a wild animal or a domesticated animal," behold, he has become a nazirite. Rabbi Yosei says, a k'vi is a unique creation unto itself, and the Sages were unable to render a decision about it, if it it is a wild animal or a domesticated animal.
