Fig alludes to the measure of a dried fig-bulk with regard to the halakhot of carrying out on Shabbat. One is liable for carrying food fit for human consumption on Shabbat, provided that he carries a dried fig-bulk of that food.

Pomegranate teaches the measure, as that which we learned in a mishna: All ritually impure wooden vessels belonging to ordinary homeowners become pure through being broken, as broken vessels cannot contract or maintain ritual impurity, and they are considered broken if they have holes the size of pomegranates.

The Sages interpreted: A land of olive oil and honey, as: A land, all of whose measures are olive-bulks. The Gemara poses a question: Does it enter your mind that it is a land all of whose measures are olives-bulks? Yet aren’t there those measures that we just mentioned above, which are not olive-bulks? Rather, say: A land, most of whose measures are olive-bulks, as most measures, e.g., those relating to forbidden foods and to impurity imparted by a corpse in a tent and by contact with an animal carcass, are olive-bulks.

Honey, i.e., dates from which date honey is extracted, also determines a measure, as with regard to eating on Yom Kippur, one is liable only if he eats a large date-bulk of food. Clearly, the measurements pertaining to mitzvot are explicitly written in the Torah and were not transmitted to Moses from Sinai.

The Gemara refutes this argument: And can you hold that all these measures are explicitly written in the Torah with regard to each of the halakhot mentioned above? Rather, they are halakhot that were transmitted to Moses from Sinai, and the Sages based them on verses in the Torah.

Rabbi Ḥiyya bar Ashi said above that Rav said that the laws governing interpositions that invalidate ritual immersion are halakhot transmitted to Moses from Sinai. The Gemara challenges this assertion: These, too, are written in the Torah, as it is written: “And he shall bathe all his flesh in the water” (Leviticus 15:16), and the Sages derived that nothing should intervene between his flesh and the water. The definite article in the phrase “in the water” indicates that this bathing is performed in water mentioned elsewhere, i.e., specifically in the water of a ritual bath, and not in just any water. And the phrase “all his flesh” indicates that it must be in water into which all of his body can enter, i.e., in which a person can immerse his entire body at once. And how much water is that? It is a cubit by a cubit by the height of three cubits. And the Sages calculated the volume of a ritual bath of this size and determined that the waters of a ritual bath measure forty se’a. As this is derived from the Written Torah, what need is there for a halakha transmitted to Moses from Sinai?

The Gemara answers: The halakha transmitted to Moses from Sinai is needed with regard to his hair, that it too must be accessible to the water without interposition. And this is in accordance with the opinion of Rabba bar Rav Huna, as Rabba bar Rav Huna said: A single hair tied in a knot constitutes an interposition and invalidates the immersion. Three hairs tied together in a knot do not constitute an interposition, because three hairs cannot be tied so tightly that water cannot penetrate them. With regard to two hairs tied together in a knot, I do not know the halakha. This halakha with regard to hair is a halakha transmitted to Moses from Sinai.

The Gemara raises a difficulty: The halakha with regard to his hair is also written in the Torah, as it was taught in a baraita: And he shall bathe all [et kol] his flesh. The superfluous word et comes to amplify and include that which is subordinate to his flesh, and that is hair.

The Gemara answers: The halakha transmitted to Moses from Sinai comes to teach the details of interpositions on the body with regard to its majority and its minority, and with regard to one who is particular and one who is not particular, in accordance with the opinion of Rabbi Yitzḥak.

As Rabbi Yitzḥak said: By Torah law, if there is an interposition between a person and the water, and it covers the majority of his body, and he is particular and wants the interposing substance removed, only then is it considered an interposition that invalidates immersion in a ritual bath. However, if he is not particular about that substance, it is not considered an interposition. The Sages, however, issued a decree prohibiting substances covering the majority of one’s body with regard to which he is not particular, due to substances covering the majority of one’s body with regard to which he is particular. And, they issued a decree prohibiting substances covering the minority of his body with regard to which one is particular, due to substances covering the majority of his body with regard to which one is particular.

The Gemara raises a question: Then let us also issue a decree deeming substances covering the minority of one’s body with regard to which he is not particular an interposition due to substances covering the minority of his body with regard to which one is particular, or alternatively, due to substances covering the majority of his body with regard to which he is not particular.

The Gemara answers: We do not issue that decree, because the halakha that deems both an interposition covering the minority of his body about which one is particular and an interposition covering the majority of his body about which one is not particular an interposition is itself a decree. Shall we then rise up and issue one decree to prevent violation of another decree? In any case, these details with regard to interpositions are neither written nor alluded to in the Torah; rather, they are halakhot transmitted to Moses from Sinai.

Rabbi Ḥiyya bar Ashi said that Rav said that the halakhot of partitions were transmitted to Moses from Sinai. The Gemara challenges this assertion as well: They are written in the Torah, as the fundamental principle that a partition ten handbreadths high establishes a separate domain is derived from the Torah.

As the Master said: The Holy Ark in the Tabernacle was nine handbreadths high, as the verse states that its height was a cubit and a half. A cubit contains six handbreadths, so its height totaled nine handbreadths. And the cover atop the Ark was one handbreadth, which total ten. There is a tradition that the Divine Presence does not descend into the domain of this world, which is derived from the verse that states that the Divine Presence would reveal itself from above the cover of the Ark. Apparently, a partition of ten handbreadths creates a separate domain.

The Gemara answers: The halakha transmitted to Moses from Sinai is necessary only according to the opinion of Rabbi Yehuda, who said: The cubit mentioned with regard to the building of the Tabernacle and the Temple was a large cubit of six handbreadths, whereas the cubit mentioned with regard to the sacred vessels was a cubit of five handbreadths. According to this opinion, the Ark, which was a cubit and a half, and its cover, which was a handbreadth, measured eight and a half handbreadths. Therefore, nothing can be derived with regard to a partition of ten handbreadths.

The Gemara poses a question. And according to the opinion of Rabbi Meir, who said: All the cubits were medium ones, regular cubits of six handbreadths; what can be said? Apparently, according to his opinion, the laws governing partitions are explicitly stated in the Torah.

The Gemara answers: According to the opinion of Rabbi Meir, the halakha with regard to a partition of ten handbreadths is indeed written in the Torah. However, the halakha transmitted to Moses from Sinai comes to teach other halakhot concerning partitions, e.g., the halakhot of extending [gode], according to which an existing partition is extended upward or downward to complete the requisite measure; and the halakhot of joining [lavud], according to which two solid surfaces are joined if they are separated by a gap of less than three handbreadths; and the halakhot of the curved wall of a sukka. A sukka is valid even if there are up to four cubits of invalid roofing, provided that this roofing is adjacent to one of the walls of the sukka. In that case, the invalid roofing is considered a bent extension of the wall. These concepts are certainly not written in the Torah.

The Gemara returns to the laws of alleyways: If the cross beam spanning the entrance to an alleyway was higher than twenty cubits from the ground and one comes to diminish its height, how much must he diminish it? The Gemara is surprised by the question: How much must he diminish it? The amount that he needs in order to render its height less than twenty cubits.

Rather, the space between the cross beam and the ground must, of course, be reduced to twenty cubits. However, when one raises the alleyway, how much must the width of the raised section be in order to render the alleyway fit for carrying within it? Rav Yosef said: One handbreadth. Abaye said: Four handbreadths.

The Gemara suggests: Let us say that these amora’im disagree about this: The one who said one handbreadth holds that one is permitted to utilize the area beneath the cross beam spanning the entrance to the alleyway, as he maintains that the cross beam serves as a partition, and the alleyway is considered as if it were sealed by a partition descending from the outer edge of the cross beam that faces the public domain. Since the area beneath the cross beam is part of the alleyway and is less than twenty cubits, there is a conspicuous demarcation for one standing in the alleyway.
