Daf Ditty Eruvin 4 Measurements 1 ! ִיְמצּוֹחת , ְדְָָּיאוֹיתרא ִניְנהוּ 2 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. ְַָדּארמ ָמר : ָאןוֹר ְִתָּהﬠשׁ ְוַכפֶּוֹרת ַחֶטפ , ֵיֲהר ָכּןא ָהָרֲﬠשׂ 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. ָלא ִָיאכְצר , ִַיְלבּר ְיהָוּדה ְַָדּארמ : ַתַאמּ ְָןיִבּנ ְַָבּאמּה ַבּת ָהִשׁשּׁ . ַתַאמּ ִיםֵכּל ְַָבּאמּה ַבּת ִָהשֲּׁחמ 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. ? לוּ רְ בַּ ִ י ֵמ ִאיר ְַָדּארמ : ׇכּל ַוֹמּתָהא וּיָה ְִֵבּיינוֹבנת , ַמיא ִָאיאכּ ֵַיְלרממ 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. ִַיבְּלר ִירֵמא , יִכּ ַיאֲאת ְְָאתִהכיל — ְלוּגד לוּ ְ ָ ל דוּב לוּ ְ פוֹד ֶ ן ָהוּמֲּﬠק 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. 3 RASHI רא ו ן עשת ה תרוכופ חפט - רא ו ן והוגב עשת ה חפט י ם כדת י ב ) מש ו ת ״כה : ״כב ( האומ יחוצ ותוקמ תרוכופ חפט רה י רשע ה ביכות יתרדוב ךתא לעמ פכה ו תר תונ אי פב "ק סד ו הכ )ד 'ה (. בר י יויס רואמ על ו םל אל הריד כש י נ הניכ המלט הרעמש כדת י ב שהמ י ם מש י ם הל ' ץרהוא תנן נבל י םדא הלוטמ הרעמש חפט י ם שח י ב ראץ כדת י ב יתרדוב : ךתא לעמ פכה ו תר אלאמ רשע ה וה י חמ י הצ הלעלדמ הרעמש אל שח י ב ילה שר ו ת תחתי ת אלא שר ו את רחא י ת י ח The Gemara concludes its unsuccessful challenge to Abaye’s position that in the context of sukkah and mavoi the five tefach amah is used, when Abaye is forced to admit that the issue is a debate between Tannaim. Rava, however, can maintain that there is no dispute between Tannaim on this issue. 2) Measures, interpositions and walls R’ Chiya bar Asi in the name of Rav States: Measures, interpositions and walls are laws taught to Moshe Rabbeinu on Har Sinai for which there is no source in the Torah. The assertion that measurements are Halacha L’Moshe M’Sinai is challenged from the teaching of R’ Chanan who derives many Halachos related to measurements from the verse that describes the fruit of Eretz Yisroel. 4 The Gemara answers: The Halachos are in fact Halacha L’Moshe M’Sinai and the verse was merely used by Chazal as a support for those halachos. The assertion that interpositions are Halacha L’Moshe M’Sinai is challenged. The Gemara answers: The part of the law that is Halacha L’Moshe M’Sinai is the halacha that an interposition must cover most of the body and be something that is objectionable. The Gemara explains which law related to walls is Halacha L’Moshe M’Sinai according to R’ Yehudah and R’ Meir.1 In the discussion of the varying size of the “ama” (=cubit) measurement, the Gemara points to the dimensions of the Mizbeach– the altar in the Temple – as an example of a structure with “amot” of varying sizes.2 The height of the Mizbeach (including the corner Keranot, or horns) was ten amot – but not all of the amot were measured the same way, so the total height was 58 tefahim (=handbreadths), rather than 60tefahim. There were five places on the Mizbeach that were measured in amot of five tefahim each. They were: The height of the Yesod (foundation) The width of the Yesod the width of the Sovev (the ledge around the Mizbeach) The height of the Keranot (the raised corners) The width of the Keranot prooftext: And these are the measures of the altar by cubits--the cubit is 13 גי ְִַהֵמּזַבּ חַָבּאמּוֹת, ְוֵֶאלּהִ מדּוֹת ְִַהֵמּזַבּ חַָבּאמּוֹת, a cubit and a handbreadth: the bottom shall be a cubit, and the הַאמּ ֹ;חפָטָו ְקמּהחַו יהַא ְָהַָאָמּוֵ - breadth a cubit, and the border thereof by the edge thereof ֹר ,ַחב הְּאוּבלגוּ ֶלָ - סהָּתְשׂפ יבָבָ ִ יבָבָ סהָּתְשׂפ .round about a span; and this shall be the base of the altar ,ותדגּרחמּהאה ב,ה ֵַ.ְְִֶֶַָחֶזַבֶָּזז ב,ה ,ותדגּרחמּהאה 1 Daf Digest 2 Steinzaltz (OBM) 5 Ezek 43:13 Which describes the Mizbeach it is clear that the Navi describes the Mizbeach as having two different types of “ama” measurements. Nevertheless, the passages in Ezek that deal with the measurements of the third Temple that is to be built in the future are unclear, and they are interpreted by the Sages of the Gemara in different ways. Following the discussion of different measurements, the Gemara brings Rabbi Hiyya bar Ashi in the name of Rav who says that the rules of Shi’urim (=measurements), Hatzitzim (=intervening substances) and Mehitzim (=partitions) are all based on an oral tradition received by Moshe on Mount Sinai. With regard to measurements, the Gemara objects that they are, in fact, rooted in a biblical passage because Rav Hanan interprets the verse: a land of wheat and barley, and vines and fig-trees and 8 ח ץֶרֶא הָטִּח ,הָרֹעְשׂוּ ןֶפֶגְו הָנֵאְתוּ הָנֵאְתוּ ןֶפֶגְו ,הָרֹעְשׂוּ הָטִּח ץֶרֶא ;pomegranates; a land of olive-trees and honey ;ןוֹמִּרְו ץֶרֶא - תיֵז ,ןֶמֶשׁ .שָׁבְדוּ ,ןֶמֶשׁ תיֵז Deut 8:8 describing the seven species of agricultural products with which the Land of Israel is blessed, as teaching rules about measurements. Apparently Rav Hanan perceived the praise of the Land of Israel to be so significant that even a foundational law – like establishing basic measurements – could be based upon it. As an example, Rav Hanan derives that the standard amount of food that one must eat to be held liable for eating non-Kosher (and most other prohibited foods) is the size of an olive (“Zayit”). From “Dvash” (=honey), the last of the seven species mentioned, we derive the measure of food that makes someone liable for eating on Yom Kippur – an amount of food the size of a plump date. In the realm o:8f eating that is forbidden, Yom Kippur is unique. The Torah never forbids “eating” on Yom Kippur; rather it commands the Jewish people to suffer “inuy” – affliction – on that day. The Rabbinic Sages understood this to mean that, while we should not eat, one does not reach a level of satisfaction beyond “inuy” until he eats the amount of a date (which is larger than an olive). The conclusion of the Gemara is that the derivations based on this passage can, at best, act as hints to the law, and that the true source is the oral tradition, as presented initially. RAMBAM Hil Ma’achalot Assurot 14:2 6 This measure, as all the other measurements, is a Halachah conveyed by Moses from Sinai. It is forbidden by Scriptural Law to eat even the slightest amount of a forbidden substance. Nevertheless, one receives lashes only for an olive-sized portion. If one partakes of any amount less than this measure, he is given stripes for rebellious conduct. Maimonides, following the Talmud, makes a distinction between the cubit of 6 handbreadths used in ordinary measurements, and the cubit of 5 handbreadths used in measuring the Golden Altar, the base of the altar of burnt offerings, its circuit and the horns of the altar. Rabbi Jay Kelman writes: It is impossible, at least from a Jewish perspective, to understand the Bible without the tools to interpret the text.
