מֵאֵימָתַי קוֹרִין אֶת שְׁמַע בָּעֲרָבִין מִשָּׁעָה שֶׁהַכֹּהֲנִים נִכְנָסִים לֶאֱכוֹל בִּתְרוּמָתָן עַד סוֹף הָאַשְׁמוּרָה הָרִאשׁוֹנָה דִּבְרֵי רַבִּי אֱלִיעֶזֶר
The beginning of tractate Berakhot, the first tractate in the first of the six orders of Mishna, opens with a discussion of the recitation of Shema, as the recitation of Shema encompasses an acceptance of the yoke of Heaven and of the mitzvot, and as such, forms the basis for all subsequent teachings. The Mishna opens with the laws regarding the appropriate time to recite Shema:
MISHNA: From when, that is, from what time, does one recite Shema in the evening? From the time when the priests enter to partake of their teruma. Until when does the time for the recitation of the evening Shema extend? Until the end of the first watch. The term used in the Torah (Deuteronomy 6:7) to indicate the time for the recitation of the evening Shema is beshokhbekha, when you lie down, which refers to the time in which individuals go to sleep. Therefore, the time for the recitation of Shema is the first portion of the night, when individuals typically prepare for sleep. That is the statement of Rabbi Eliezer.
וַחֲכָמִים אוֹמְרִים עַד חֲצוֹת
The Rabbis say: The time for the recitation of the evening Shema is until midnight.
רַבָּן גַּמְלִיאֵל אוֹמֵר עַד שֶׁיַּעֲלֶה עַמּוּד הַשַּׁחַר
Rabban Gamliel says: One may recite Shema until dawn, indicating that beshokhbekha is to be understood as a reference to the entire time people sleep in their beds, the whole night.
מַעֲשֶׂה וּבָאוּ בָנָיו מִבֵּית הַמִּשְׁתֶּה אָמְרוּ לוֹ לֹא קָרִינוּ אֶת שְׁמַע אָמַר לָהֶם אִם לֹא עָלָה עַמּוּד הַשַּׁחַר חַיָּיבִין אַתֶּם לִקְרוֹת וְלֹא זוֹ בִּלְבַד אָמְרוּ אֶלָּא כָּל מַה שֶּׁאָמְרוּ חֲכָמִים עַד חֲצוֹת מִצְוָתָן עַד שֶׁיַּעֲלֶה עַמּוּד הַשַּׁחַר
The mishna relates that Rabban Gamliel practiced in accordance with his ruling. There was an incident where Rabban Gamliel’s sons returned very late from a wedding hall. They said to him, as they had been preoccupied with celebrating with the groom and bride: We did not recite Shema. He said to them: If the dawn has not yet arrived, you are obligated to recite Shema. Since Rabban Gamliel’s opinion disagreed with that of the Rabbis, he explained to his sons that the Rabbis actually agree with him, and that it is not only with regard to the halakha of the recitation of Shema, but rather, wherever the Sages say until midnight, the mitzva may be performed until dawn.
הֶקְטֵר חֲלָבִים וְאֵבָרִים מִצְוָתָן עַד שֶׁיַּעֲלֶה עַמּוּד הַשַּׁחַר וְכָל הַנֶּאֱכָלִים לְיוֹם אֶחָד מִצְוָתָן עַד שֶׁיַּעֲלֶה עַמּוּד הַשַּׁחַר אִם כֵּן לָמָה אָמְרוּ חֲכָמִים עַד חֲצוֹת כְּדֵי לְהַרְחִיק אָדָם מִן הָעֲבֵירָה:
Rabban Gamliel cites several cases in support of his claim, such as the burning of fats and limbs on the altar. Due to the quantity of offerings each day, the priests were often unable to complete the burning of all of the fats and limbs, so they continued to be burned into the night, as it is written: “This is the law of the burnt offering: The burnt offering shall remain upon the pyre on the altar all night until morning, while the fire on the altar burns it” (Leviticus 6:2). And, with regard to all sacrifices, such as the sin-offerings and the guilt-offerings that are eaten for one day and night; although the Sages state that they may be eaten only until midnight, by Torah law they may be eaten until dawn. This is in accordance with the verse: “On the day on which it is offered must you eat. Do not leave it until the morning” (Leviticus 7:15). If so, why did the Sages say that they may be eaten only until midnight? This is in order to distance a person from transgression, as if one believes that he has until dawn to perform the mitzva, he might be negligent and postpone it until the opportunity to perform the mitzva has passed.
גמ' תַּנָּא הִיכָא קָאֵי דְּקָתָנֵי מֵאֵימָתַי
GEMARA: The Mishna opens with the laws concerning the appropriate time to recite Shema with the question: From when does one recite Shema in the evening? With regard to this question, the Gemara asks: On the basis of what prior knowledge does the tanna of our mishna ask: From when? It would seem from his question that the obligation to recite Shema in the evening was already established, and that the tanna seeks only to clarify details that relate to it. But our mishna is the very first mishna in the Talmud.
וְתוּ מַאי שְׁנָא דְּתָנֵי בְּעַרְבִית בְּרֵישָׁא לִתְנֵי דְּשַׁחֲרִית בְּרֵישָׁא
The Gemara asks: And furthermore, what distinguishes the evening Shema, that it was taught first? Let the tanna teach regarding the recitation of the morning Shema first. Since most mitzvot apply during the day, the tanna should discuss the morning Shema before discussing the evening Shema, just as the daily morning offering is discussed before the evening offering (Tosefot HaRosh).
תַּנָּא אַקְּרָא קָאֵי דִּכְתִיב בְּשָׁכְבְּךָ וּבְקוּמֶךָ וְהָכִי קָתָנֵי זְמַן קְרִיאַת שְׁמַע דִּשְׁכִיבָה אֵימַת מִשָּׁעָה שֶׁהַכֹּהֲנִים נִכְנָסִין לֶאֱכוֹל בִּתְרוּמָתָן
The Gemara offers a single response to both questions: The tanna bases himself on the verse as it is written: “You will talk of them when you sit in your home, and when you walk along the way, when you lie down, and when you arise” (Deuteronomy 6:7). By teaching the laws of the evening Shema first, the tanna has established that the teachings of the Oral Torah correspond to that which is taught in the Written Torah. And based on the Written Torah, the tanna teaches the oral law: When is the time for the recitation of Shema of lying down as commanded in the Torah? From when the priests enter to partake of their teruma. Just as the Written Torah begins with the evening Shema, so too must the Oral Torah.
וְאִי בָּעֵית אֵימָא יָלֵיף מִבְּרִיָּיתוֹ שֶׁל עוֹלָם דִּכְתִיב וַיְהִי עֶרֶב וַיְהִי בֹקֶר יוֹם אֶחָד
However, there is another possible explanation for why the mishna opens with the evening Shema rather than with the morning Shema. If you wish, you could say instead that the tanna derives the precedence of the evening Shema from the order of the creation of the world. As it is written in the story of creation: “And there was evening, and there was morning, one day” (Genesis 1:5). According to this verse, day begins with the evening and not the morning. For both of these reasons it was appropriate to open the discussion of the laws of the recitation of Shema with the evening Shema.
אִי הָכִי סֵיפָא דְּקָתָנֵי בַּשַּׁחַר מְבָרֵךְ שְׁתַּיִם לְפָנֶיהָ וְאַחַת לְאַחֲרֶיהָ בָּעֶרֶב מְבָרֵךְ שְׁתַּיִם לְפָנֶיהָ וּשְׁתַּיִם לְאַחֲרֶיהָ לִתְנֵי דְּעַרְבִית בְּרֵישָׁא
The Gemara asks: If so, why does the latter clause of the mishna, which appears later in the chapter, teach: In the morning one recites two blessings before Shema and one blessing afterward, and in the evening one recites two blessings before Shema and two afterward? Based upon the above reasoning, the mishna should have taught the blessing recited before and after the evening Shema first.
תַּנָּא פָּתַח בְּעַרְבִית וַהֲדַר תָּנֵי בְּשַׁחֲרִית עַד דְּקָאֵי בְּשַׁחֲרִית פָּרֵישׁ מִילֵּי דְשַׁחֲרִית וַהֲדַר פָּרֵישׁ מִילֵּי דְעַרְבִית:
The Gemara answers: Indeed, the tanna began by discussing the laws regarding the recitation of the evening Shema, and then taught the laws regarding the recitation of the morning Shema. Once he was already dealing with the morning Shema, he explained the matters of the morning Shema, and then explained the matters of the evening Shema.
אָמַר מָר מִשָּׁעָה שֶׁהַכֹּהֲנִים נִכְנָסִים לֶאֱכוֹל בִּתְרוּמָתָן מִכְּדִי כֹּהֲנִים אֵימַת קָא אָכְלִי תְּרוּמָה מִשְּׁעַת צֵאת הַכּוֹכָבִים לִתְנֵי מִשְּׁעַת צֵאת הַכּוֹכָבִים
The Gemara proceeds to clarify the rest of the mishna. The Master said in the mishna that the beginning of the period when one recites Shema in the evening is when the priests enter to partake of their teruma. However, this does not specify a definitive time. When do the priests enter to partake of their teruma? From the time of the emergence of the stars. If that is the case, then let the tanna teach that the time for the recitation of the evening Shema is from the time of the emergence of the stars.
מִלְּתָא אַגַּב אוֹרְחֵיהּ קָמַשְׁמַע לָן כֹּהֲנִים אֵימַת קָא אָכְלִי בִּתְרוּמָה מִשְּׁעַת צֵאת הַכּוֹכָבִים וְהָא קָמַשְׁמַע לָן דְּכַפָּרָה לָא מְעַכְּבָא כִּדְתַנְיָא וּבָא הַשֶּׁמֶשׁ וְטָהֵר בִּיאַת שִׁמְשׁוֹ מְעַכַּבְתּוֹ מִלֶּאֱכוֹל בִּתְרוּמָה וְאֵין כַּפָּרָתוֹ מְעַכַּבְתּוֹ מִלֶּאֱכוֹל בִּתְרוּמָה
The Gemara responds: Indeed it would have been simpler to say that the time for the recitation of the evening Shema begins with the emergence of the stars, but the particular expression used by the tanna teaches us another matter in passing: When do priests partake of their teruma? From the time of the emergence of the stars. And the tanna teaches us a new halakha parenthetically: failure to bring an atonement offering does not prevent a priest from eating teruma. In cases where an impure priest is required to immerse himself in a ritual bath and bring an atonement offering, even if he already immersed himself, he is not completely ritually pure until he brings the atonement offering. Nevertheless, he is still permitted to partake of teruma. Taught in passing in our mishna, this is articulated fully in a baraita, based on a close reading of the biblical passages. As it was taught in a baraita with regard to the laws of ritual impurity, it is said: “One who touches it remains impure until evening. He should not eat of the consecrated items and he must wash his flesh with water. And the sun sets and it is purified. Afterwards, he may eat from the teruma, for it is his bread” (Leviticus 22:6–7). From the passage: “And the sun sets and it is purified,” that the absence of the setting of his sun prevents him from partaking of teruma, but failure to bring the atonement offering does not prevent him from partaking of teruma, may be inferred.
וּמִמַּאי דְּהַאי וּבָא הַשֶּׁמֶשׁ בִּיאַת הַשֶּׁמֶשׁ וְהַאי וְטָהֵר טְהַר יוֹמָא
The Gemara discusses the proof offered in the baraita: From where do we know that the phrase: “And the sun sets” refers to the complete setting of the sun, and therefore, “and it is purified” refers to the fact that the day is pure, i.e., and the sun sets and it is purified is one phrase meaning that the sun will set, the air will clear, and the stars will emerge (Rav Hai Gaon)?
