אֵין בּוֹ;

whether there is not the measure that determines liability in the piece he ate, he must bring a provisional guilt offering.

שׁוּמָּן וְחֵלֶב לְפָנָיו, וְאָכַל אֶחָד מֵהֶן וְאֵינוֹ יוֹדֵעַ אֵיזֶה מֵהֶן אָכַל; אִשְׁתּוֹ וַאֲחוֹתוֹ עִמּוֹ בַּבַּיִת, שָׁגַג בְּאַחַת מֵהֶן וְאֵינוֹ יוֹדֵעַ בְּאֵיזוֹ מֵהֶן שָׁגַג; שַׁבָּת וְיוֹם חוֹל, וְעָשָׂה מְלָאכָה בְּאֶחָד מֵהֶן וְאֵינוֹ יוֹדֵעַ בְּאֵיזוֹ מֵהֶן עָשָׂה – מֵבִיא אָשָׁם תָּלוּי.

If one has a piece of permitted fat and a piece of forbidden fat before him and he ate one of them and he does not know which of them he ate; or if his wife and his sister were with him in the house and he unwittingly engaged in intercourse with one of them and he does not know with which of them he unwittingly engaged in intercourse; or if he confused Shabbat and a weekday and he performed labor prohibited on Shabbat on one of the days and he does not know on which of them he performed the labor, in all of those cases he is liable to bring a provisional guilt offering.

כְּשֵׁם שֶׁאִם אָכַל חֵלֶב וְחֵלֶב בְּהֶעְלֵם אַחַת אֵינוֹ חַיָּיב אֶלָּא חַטָּאת אַחַת, כֵּן עַל לֹא הוֹדַע שֶׁלָּהֶן – אֵינוֹ מֵבִיא אֶלָּא אָשָׁם תָּלוּי אֶחָד;

Just as in a case where one unknowingly ate a piece of forbidden fat and then another piece of forbidden fat in a single lapse of awareness he is liable to bring only one sin offering, so too, in a case where their status is unknown to him and he ate them both unwittingly during a single lapse in awareness, he is liable to bring only one provisional guilt offering.

אִם הָיְתָה יְדִיעָה בֵּינְתַּיִם, כְּשֵׁם שֶׁהוּא מֵבִיא חַטָּאת עַל כָּל אַחַת וְאַחַת – כָּךְ מֵבִיא אָשָׁם תָּלוּי עַל כָּל אַחַת וְאַחַת;

But if he had gained knowledge between the first and second instance of eating that there is a possibility the fat might be prohibited, then the halakha is different: Just as he would be liable to bring a sin offering for each and every piece when he gained knowledge of their prohibited status in between each act of consumption, so too, he must bring a provisional guilt offering for each and every instance in which he consumed food that might be forbidden after learning of their uncertain status in between each unwitting act of consumption.

כְּשֵׁם שֶׁאָכַל חֵלֶב וְדָם וּפִיגּוּל וְנוֹתָר בְּהֶעְלֵם אַחַת – חַיָּיב עַל כָּל אַחַת וְאַחַת, כָּךְ עַל לֹא הוֹדַע שֶׁלָּהֶן – מֵבִיא אָשָׁם תָּלוּי עַל כָּל אַחַת וְאַחַת.

Just as in a case where one ate forbidden fat, and blood, and piggul, and notar in one lapse of awareness he is liable to bring a sin offering for each and every one, so too, with regard to a case where their status is unknown to him and he ate them unwittingly during one lapse of awareness, he must bring a provisional guilt offering for each and every item.

גמ׳ אִיתְּמַר, רַב אַסִי אָמַר: חֲתִיכָה אַחַת שָׁנִינוּ, סָפֵק שֶׁל חֵלֶב סָפֵק שֶׁל שׁוּמָּן. חִיָּיא בַּר רַב אָמַר: חֲתִיכָה מִשְּׁתֵּי חֲתִיכוֹת שָׁנִינוּ.

With regard to the mishna’s mention of one who ate a piece of fat whose status was uncertain, it was stated that Rav Asi says: We learned that one is liable to bring a provisional guilt offering in the case of one single piece that is uncertain if it is of forbidden fat and uncertain if it is of permitted fat. Ḥiyya bar Rav disagreed and said: We learned this halakha in the case of an uncertainty involving one piece out of two pieces, one of which is forbidden fat and the other permitted fat, but in the case of a single piece, one who consumes it is not liable to bring an offering.

בְּמַאי קָא מִיפַּלְגִי? רַב אַסִי סָבַר: יֵשׁ אֵם לַמָּסוֹרֶת, ״מִצְוַת״ כְּתִיב;

The Gemara inquires: With regard to what matter do Rav Asi and Ḥiyya bar Rav disagree? The Gemara answers: It is stated in a verse discussing the obligation to bring a provisional guilt offering: “And if anyone sin, and do any of the commandments [mitzvot] of the Lord that are not to be done, though does not know it; yet is he guilty, and shall bear his iniquity” (Leviticus 5:17). Rav Asi holds: The tradition of the manner in which the verses in the Torah are written is authoritative, and one derives halakhot based on the spelling of the words. Therefore, the obligation to bring a provisional guilt offering applies only when there is uncertainty with regard to a single piece, because the word is written as “ mitzvat,” in the singular form.

וְחִיָּיא בַּר רַב אָמַר: יֵשׁ אֵם לַמִּקְרָא, ״מִצְווֹת״ קָרֵינַן.

And Ḥiyya bar Rav says: The vocalization of the Torah is authoritative, meaning that one derives halakhot based on the pronunciation of the words, even if it diverges from the spelling. Therefore, since we read the word in the plural, as mitzvot, the obligation to bring a provisional guilt offering applies only when two pieces are present.

אֵיתִיבֵיהּ רַב הוּנָא לְרַב אַסִי, וְאָמְרִי לָהּ חִיָּיא בַּר רַב לְרַב אַסִי: חֵלֶב וְשׁוּמָּן לְפָנָיו וְאָכַל אַחַת מֵהֶן; מַאי לָאו מִדְּסֵיפָא שְׁתֵּי חֲתִיכוֹת – רֵישָׁא נַמִי שְׁתֵּי חֲתִיכוֹת?

Rav Huna raised an objection to Rav Asi, and some say it was Ḥiyya bar Rav who raised the objection to Rav Asi: The latter clause in the mishna states: If one has a piece of permitted fat and a piece of forbidden fat before him and he ate one of them. What, is it not correct to infer from the fact that the latter clause of the mishna is referring to two pieces that the first clause, which introduces the topic, is also referring to two pieces?

אֲמַר לְהוּ רַב: לָא תֵּיזְלָא בָּתַר אִיפְּכָא, דְּיָכוֹל לְשַׁנּוּיֵי לְכוּ: סֵיפָא – בִּשְׁתֵּי חֲתִיכוֹת, רֵישָׁא – בַּחֲתִיכָה אַחַת. אִי הָכִי, יֵשׁ לוֹמַר: חֲתִיכָה אַחַת מִחַיַּיב, שְׁתֵּי חֲתִיכוֹת צְרִיכָא לְמֵימַר? זוֹ וְאֵין צָרִיךְ לְמֵימַר זוֹ.

Rav said to them: Do not go after the opposite, i.e., do not cite a proof from a source that could be understood in the reverse manner, as Rav Asi can answer you by claiming that whereas the latter clause is referring to two pieces, the first clause is referring to one piece. The Gemara questions this claim: If so, one can say that once the mishna has taught that the consumption of one piece of fat that might be forbidden renders him obligated to bring a provisional guilt offering, does it need to be said that the same applies in a case involving two pieces, where one of them is definitely forbidden? The Gemara answers that the mishna is employing the style: This, and it is unnecessary to say that, i.e., it first teaches the more difficult and novel case, then teaches the easier, more straightforward one.

וּלְחִיָּיא בַּר רַב דְּאָמַר: מִדְּסֵיפָא בִּשְׁתֵּי חֲתִיכוֹת – רֵישָׁא נַמִי בִּשְׁתֵּי חֲתִיכוֹת, מִיתְנָא תַּרְתֵּי לָמָּה לִי? פֵּרוּשֵׁי קָא מְפָרֵשׁ: סָפֵק אָכַל סָפֵק לֹא אָכַל חֵלֶב – מֵבִיא אָשָׁם תָּלוּי, כֵּיצַד? כְּגוֹן שֶׁהָיָה חֵלֶב וְשׁוּמָּן לְפָנָיו.

The Gemara asks: And according to the opinion of Ḥiyya bar Rav, who says that from the fact that the latter clause of the mishna is referring to two pieces, the first clause is also is referring two pieces, why do I need two clauses to teach the same halakha? The Gemara answers that the mishna is explaining itself, as follows: If there is uncertainty whether one ate forbidden fat and uncertainty whether one did not eat forbidden fat, he must bring a provisional guilt offering. How so? For example, in a case where there was forbidden fat and permitted fat before him, and he ate one of them.

אָמַר רַב יְהוּדָה אָמַר רַב: הָיוּ לְפָנָיו שְׁתֵּי חֲתִיכוֹת, אַחַת שֶׁל שׁוּמָּן וְאַחַת שֶׁל חֵלֶב, אָכַל אַחַת מֵהֶן וְאֵינוֹ יוֹדֵעַ אֵיזוֹ מֵהֶן אָכַל – חַיָּיב; חֲתִיכָה אַחַת, סָפֵק שֶׁל חֵלֶב סָפֵק שֶׁל שׁוּמָּן וַאֲכָלָהּ – פָּטוּר.

§ The Gemara cites a series of virtually identical statements attributed to Rav, followed by different rationales for his opinion, after each of which it raises several objections from a baraita or a mishna. Rav Yehuda says that Rav says: In a case where one had two pieces of fat before him, one of permitted fat and one of forbidden fat, if he ate one of them and he does not know which of them he ate, he is obligated to bring a provisional guilt offering. But if there was only one piece before him and there was uncertainty whether it was of forbidden fat and uncertainty whether it was of permitted fat, and he ate it, he is exempt.

אֲמַר רָבָא: מַאי טַעְמָא דְּרַב? דְּאָמַר קְרָא: ״וְעָשָׂה אַחַת מִכָּל מִצְוֹת ה׳ בִּשְׁגָגָה״ – עַד שֶׁיִּשְׁגּוֹג בִּשְׁתַּיִם, ״מִצְוַת״ כְּתִיב, ״מִצְווֹת״ קָרֵינַן.

Rava said: What is the reason for the opinion of Rav? He derives it from that which the verse states: “And if anyone sin, and do any of the commandments [mitzvot] of the Lord that are not to be done, though he does not know it; yet is he guilty, and shall bear his iniquity” (Leviticus 5:17). Rav derives from the plural mitzvot that one is not liable to bring a provisional guilt offering until he is unwitting with regard to one of two items, which in this case is two pieces of fat. The Gemara asks: But isn’t it written “ mitzvat,” in the singular form? The Gemara answers: We read it as mitzvot, in the plural. In other words, according to Rava, Rav maintains that the vocalization of the Torah is authoritative.

אֵיתִיבֵיהּ אַבַּיֵי, רַבִּי אֱלִיעֶזֶר אוֹמֵר: כּוֹי, חַיָּיבִין עָלָיו אָשָׁם תָּלוּי!

Abaye raised an objection to Rava from a baraita. Rabbi Eliezer says: With regard to a koy, a kosher animal with characteristics of both a domesticated animal and a non-domesticated animal, one is obligated to bring a provisional guilt offering for eating its fat. The prohibition of forbidden fats applies only to those of a domesticated animal; the corresponding fats are permitted in the case of a non-domesticated animal. Since a koy is of uncertain status, one must bring a provisional guilt offering for eating its fat. Evidently, one is liable to bring a provisional guilt offering even in a case where there was uncertainty involving a single item.

אֲמַר לוֹ, רַבִּי אֱלִיעֶזֶר סָבַר: יֵשׁ אֵם לַמָּסוֹרֶת, ״מִצְוַת״ כְּתִיב.

Rava said to Abaye: Rabbi Eliezer holds that the tradition of the manner in which the verses in the Torah are written is authoritative. Consequently, as the singular form “ mitzvat ” is written, he maintains that a provisional guilt offering must be brought in a case of uncertainty involving a single item, such as the fat of a koy.

אֵיתִיבֵיהּ: סָפֵק בֶּן תִּשְׁעָה לָרִאשׁוֹן אוֹ בֶּן שִׁבְעָה לָאַחֲרוֹן – יוֹצִיא וְהַוָּלָד כָּשֵׁר,

The Gemara raised an objection to Rav from a baraita: If one consummates levirate marriage with his yevama and seven months later she gives birth, there is uncertainty whether the child is nine months old, i.e., counting from conception, and is the offspring of the first husband, whether the child is only seven months old and is the offspring of the latter husband, i.e., the yavam, not the deceased, in which case the levirate bond did take effect. In such a situation, due to the possibility that she is forbidden to him as his brother’s wife, he must divorce her. But the offspring is of unflawed lineage, as whether it was born from the first or the second husband, its conception involved no transgression.

וְחַיָּיב בְּאָשָׁם תָּלוּי! הָא מַנִּי? רַבִּי אֱלִיעֶזֶר הִיא.

The baraita concludes: And to atone for the possibility that they engaged in forbidden intercourse they are each obligated to bring a provisional guilt offering. This indicates that one is obligated to bring a provisional guilt offering even when the uncertainty involves a single item. The Gemara answers: In accordance with whose opinion is this baraita? It is in accordance with the opinion of Rabbi Eliezer, who, as stated above, maintains that one is obligated to bring a provisional guilt offering for uncertainty involving a single item.

אֵיתִיבֵיהּ: נִמְצָא עַל שֶׁלּוֹ – טְמֵאִין וְחַיָּיבִין בְּקָרְבָּן,

The Gemara raised another objection to Rav from a mishna (Nidda 14a): It is the custom of Jewish women to engage in intercourse with their husbands with two cloths, one for her husband to wipe himself with to see if any of her blood is on him after intercourse, and one for her to check herself to ascertain after intercourse whether her menstrual flow has begun. If after intercourse blood was found on his cloth, are both ritually impure for seven days, in accordance with the halakha of a menstruating woman and a man who engages in intercourse with her, and they are each liable to bring a sin offering for unwittingly performing an action punishable by karet.

עַל שֶׁלָּהּ אֹתְיוֹם – טְמֵאִין וְחַיָּיבִין בְּקָרְבָּן, נִמְצָא עַל שֶׁלָּהּ לְאַחַר זְמָן – טְמֵאִין מִסָּפֵק וּפְטוּרִין מִן הַקָּרְבָּן; וְתָנֵי עֲלָהּ: חַיָּיב מִשּׁוּם אָשָׁם תָּלוּי! הָא מַנִּי? רַבִּי אֱלִיעֶזֶר הִיא.

The mishna continues: If blood was found on her cloth immediately [otyom] after intercourse, the woman and her husband are likewise ritually impure for seven days and are each liable to bring a sin offering. If blood was found on her cloth after time passed, they are both impure due to uncertainty, as it is possible the blood appeared only after intercourse, and they are exempt from bringing the sin offering. And it is taught with regard to this last case in the mishna: They are each nevertheless liable to bring a provisional guilt offering. The Gemara again answers: In accordance with whose opinion is this mishna? It is in accordance with the opinion of Rabbi Eliezer.

אָמַר רַבִּי חִיָּיא אָמַר רַב: הָיוּ לְפָנָיו שְׁתֵּי חֲתִיכוֹת, אַחַת שֶׁל חֵלֶב וְאַחַת שֶׁל שׁוּמָּן, וְאָכַל אַחַת מֵהֶן וְאֵינוֹ יוֹדֵעַ אֵיזֶה מֵהֶן אָכַל – חַיָּיב; חֲתִיכָה סָפֵק שֶׁל שׁוּמָּן סָפֵק שֶׁל חֵלֶב, וַאֲכָלָהּ – פָּטוּר.

§ Rabbi Ḥiyya says that Rav says: In a case where one had two pieces of fat before him, one of permitted fat and one of forbidden fat, and he ate one of them and he does not know which of them he ate, he is obligated to bring a provisional guilt offering. But if there was only one piece before him and there was uncertainty whether it was of permitted fat and uncertainty whether it was of forbidden fat, and he ate it, he is exempt.

אֲמַר רַבִּי זֵירָא: מַאי טַעְמָא דְּרַב? קָסָבַר: שְׁתֵּי חֲתִיכוֹת – אֶפְשָׁר לְבָרֵר אִיסּוּרוֹ, חֲתִיכָה אַחַת – אִי אֶפְשָׁר לְבָרֵר אִיסּוּרוֹ.

Rabbi Zeira said: What is the reason for the ruling of Rav? He holds one is liable to bring a provisional guilt offering only in a case involving two pieces, as it is possible to identify its prohibition. As, an expert might later examine the remaining piece and determine whether or not one ate the prohibited piece. By contrast, in a case of uncertainty involving only one piece, it is impossible to identify its prohibition and ascertain whether one ate a forbidden or permitted piece of fat.

מַאי אִיכָּא בֵּין טַעְמָא דְּרָבָא לְטַעְמָא דְּרַבִּי זֵירָא? אִיכָּא בֵּינַיְיהוּ כְּזַיִת וּמֶחֱצָה,

The Gemara asks: What difference is there between the reason given earlier by Rava for Rav’s ruling and the reason stated here by Rabbi Zeira? The Gemara answers: The difference between them is a case where there were two pieces before a person, one measuring an olive-bulk and the other measuring one-half of an olive-bulk. Since according to halakha a measure of less than an olive-bulk is of no relevance in such a case, it is considered as though only one piece is present before him.

לְרָבָא – לֵיכָּא ״מִצְווֹת״ וּפָטוּר, לְרַבִּי זֵירָא – אֶפְשָׁר לְבָרֵר אִיסּוּרוֹ.

The Gemara elaborates: According to Rava, who contends that Rav maintains that the plural vocalization of the Torah is authoritative, this is not a case of uncertainty involving two items, as required by the plural form mitzvot, and therefore he is exempt. By contrast, according to Rabbi Zeira, this is a case where it is possible to identify its prohibition by examining the remaining piece, and he is therefore obligated to bring a provisional guilt offering.

אֵיתִיבֵיהּ רַבִּי יִרְמְיָה לְרַבִּי זֵירָא, רַבִּי אֱלִיעֶזֶר אוֹמֵר: כּוֹי, חַיָּיבִין עַל חֶלְבּוֹ אָשָׁם תָּלוּי! אֲמַר לֵיהּ: רַבִּי אֱלִיעֶזֶר סָבַר לָא בָּעֵינַן לְבָרֵר אִיסּוּרוֹ.

Rabbi Yirmeya raised an objection to Rabbi Zeira from a baraita. Rabbi Eliezer says: With regard to a koy, one is obligated to bring a provisional guilt offering for eating its fat. Evidently, one must bring a provisional guilt offering even in a case where the uncertainty involves only a single item. Rabbi Zeira said to Rabbi Yirmeya: Rabbi Eliezer holds we do not require a case where it is possible to identify its prohibition in order for one to be obligated to bring a provisional guilt offering.
