Mishnayos Kerisos Perek 4 Mishnah 1
כריתות פרק ד׳ משנה א׳
Bartenura
ספק אכל חלב ספק לא אכל. והיכי דמי, כגון חלב ושומן לפניו ואכל את אחד מהן, כדתני בסיפא. ופרושי קמפרש, ספק אכל חלב ספק לא אכל כיצד, כגון שהיה חלב ושומן לפניו ויש כאן איסור קבוע אבל אם היתה לפניו חתיכה אחת, ספק שהיא חלב ספק שהיא שומן ואכלה, פטור, דלא איקבע איסורא:
ואפילו אכל. ודאי חלב, ספק יש בו כזית. וכגון שבשעה שאכלו סבור שומן הוא ואח״כ נודע לו שהוא חלב, וספק יש בו כזית ספק אין בו:
אכל את אחד מהן. וכסבור שומן הוא, ואחר כך נודע שהאחד היה חלב, וזה אינו יודע איזו אכל, מביא אשם תלוי. אבל אם בשעת אכילה היתה לו ספק והזיד ואכלה מספק, הוי מזיד ופטור:
שגג באחת מהן. כסבור זו אשתו, ואחר כך נתספק איזו מהן היתה, מביא אשם תלוי:
Mishnah 2
Mishnayos Kerisos Perek 4 Mishnah 2
כריתות פרק ד׳ משנה ב׳
Bartenura
כך על לא הודע שלהן – as for example, he ae two pieces [of meat] thinking that both of them were permitted fat, and afterwards became informed/conscious that each one of them was doubtful [as to whether it was permitted fat or prohibited fat], he doesn’t bring anything other than one suspended guilt-offering, since he was not informed of it between each consuming that he ate doubtful forbidden fat.
ואם היתה ידיעה בינתים – the awareness of the doubt.
כשם שהוא מביא חטאת על כל אחת ואחת – if there was certain knowledge/awareness in-between, so too, with awareness/knowledge of doubtful consumption [of forbidden fat], he brings two suspended guilt-offerings.
חלב ונותר לפניו – and he thought that both of them were permitted fat that is acceptable.
אשתו נדה ואחותו עמו בבית – he had sexual intercourse with one of them, while thinking to have sex with his ritually pure wife, and it was found that his wife was a menstruating woman, and another doubt, as to which of them (i.e., his sister or his menstruating wife) he had sexual relations with.
ועשה מלאכה בהן בין השמשות – thinking that it was a weekday.
ר' אליעזר מחייב חטאת – whichever way you turn , if he ate forbidden fat, he is liable, if he ate left-over, he is liable, and similarly for all of them.
ורבי יהושע פוטר – for regarding the sin-offering, it is written (Leviticus 4:13): “or the sin of which he is guilty [is brought to his knowledge – he shall bring as his offering a male goat without blemish],” until he would be made known to him in how he sinned. And Rabbi Eliezer [states] that this “of the sin of which he is guilty” is needed except for someone acting unawares (i.e., having n intention of doing so) the labors on the Sabbath, as for example, he had intended to cut off what was detached but cut what was attached, that he is exempt, for since he didn’t intend to make a forbidden cutting, and especially when acting unawares with work on Shabbat that he is exempt, because the Torah forbade planned, thoughtful, creative labor, but acting unawares regarding fats and illicit sexual relationships, as, for example, that he ate fat or he had sexual relations with someone forbidden to him on account of consanguinity that he didn’t intend, he is liable, according to everyone, for he benefitted [from it].
לא נחלקו – Rabbi Eliezer who stated that we don’t require that he knew in what he had sinned, he did not dispute on Rabbi Yehoshua, and he agrees with him that a person who does creative work at twilight whether on Shabbat or on Yom Kippur, he is exempt.
שאני אומר – half the measure of creative work was done on Shabbat and half the measurement on Yom Kippur, and there isn’t here the liability of a sin-offering.
מעין איזה מלאכה עשה – if he ploughed or sowed.
פוטרו היה רבי יהושע אף מאשם תלוי – for regarding the suspended guilt offering, it is written (Leviticus 5:17): “And when a person, without knowing it, [sins in regard to any of the LORD’s commandments about things not to be done, and then realizes his guilt],” excluding this one who knows that he sinned, but rather, that the sin is not something specific, and the sin-offering he is also not liable for, for even though he knew that he sinned, whichever way you turn, anyway, it was not made clear to him in what he way he had sinned. But the Halakhic decision is that he is liable for a suspended guilt-offering, whether regarding fat and left-over before him, where it is possible to have the matter verified, whether with regarding to performing creative labor at twilight, whether on Shabbat or on Yom Kippur, where it is impossible to have the matter verified, and similarly with his wife who is a menstruating woman and his sister in the house, and he acted inadvertently with one of them, in all of these, he brings a suspended guilt-offering.
כך על לא הודע שלהן. כגון אכל שתי חתיכות כסבור ששתיהן שומן הן ואחר כך נודע שכל אחת מהן ספק, אינו מביא אלא אשם תלוי אחד, הואיל ולא נודע לו בין אכילה לאכילה שספק חלב אכל:
ואם היתה ידיעה בינתים. ידיעת ספק:
כשם שהוא מביא חטאת על כל אחת ואחת. אם היתה ידיעת ודאי בינתיים, כך בידיעת ספק מביא שני אשמות תלויין:
חלב ונותר לפניו. וסבר דשניהן שומן של היתר:
אשתו נדה ואחותו עמו בבית. בא על אחת מהן כסבור לבוא על אשתו טהורה, ונמצא שאשתו היתה נדה, ועוד ספק על איזו מהן בא:
ועשה מלאכה בין השמשות. כסבור חול הוא:
ר׳ אליעזר מחייב חטאת. ממה נפשך, אם חלב אכל חייב, אם נותר אכל חייב, וכן כולם:
ורבי יהושע פוטר. דגבי חטאת כתיב (ויקרא ד׳:כ״ג,) אשר חטא בה, עד שיוודע לו במה חטא. ור׳ אליעזר, האי אשר חטא בה מיבעי ליה פרט למתעסק במלאכת שבת, כגון נתכוין לחתוך את התלוש וחתך את המחובר, שהוא פטור, כיון דלא נתכוין לחתיכה דאיסורא. ודוקא מתעסק במלאכת שבת הוא דפטור, דמלאכת מחשבת אסרה תורה. אבל מתעסק בחלבים ובעריות, כגון שאכל חלב או בא על הערוה שלא במתכוין, חייב לכולי עלמא, שהרי נהנה:
לא נחלקו. ר׳ אליעזר דאמר לא בעינן שידע במה חטא לא נחלק על רבי יהושע, ומודה לו בעושה מלאכה בין השמשות שבין שבת ויום הכפורים שהוא פטור:
שאני אומר. חצי שיעור המלאכה נעשית בשבת וחצי שיעור ביום הכפורים, ואין כאן חיוב חטאת:
מעין איזו מלאכה עשה. אם חרש או זרע:
פוטרו היה רבי יהושע אף מאשם תלוי. דגבי אשם תלוי כתיב (ויקרא ה׳) כי תחטא ולא ידע, פרט לזה שידע שחטא אלא שאין החטא מסויים. וחטאת נמי לא מיחייב, שאע״פ שידע שחטא ממה נפשך, מכל מקום לא הוברר לו במה חטא. ופסק ההלכה, שהוא חייב באשם תלוי בין בחלב ונותר לפניו שאפשר שיוברר הדבר, בין בעושה מלאכה בין השמשות שבין שבת ויוה״כ שאי אפשר שיוברר הדבר, וכן באשתו נדה ואחותו עמו בבית ושגג באחת מהן, בכל אלו מביא אשם תלוי:

After World War II, in 1947, Rav Yonah Sztencl, a disciple of Rav Frommer, expanded the program, advocating for a comprehensive study of Shishah Sidrei Mishnah. The idea of studying two Mishnayos daily gained the support of figures like Rav Isser Zalman Meltzer, the Tchebiner Rov, and the Gerer Rebbe, marking the formal inception of Mishnah Yomi.

ספק אכל חלב ספק לא אכל – and how is this to be understood? As, for example, forbidden fat and permitted were before him and he ate one of them, as is taught in the ending clause. And it is specified as it explains: It is doubtful whether he at forbidden fat and it is doubtful that he did not eat it. How so? As, for example, that the forbidden fat and permitted fat were before him and there is a fixed prohibition. But if there was before him one piece, it is doubtful whether it is forbidden fat and doubtful that it is permitted fat and he ate it, he is exempt. For the prohibition was not fixed.
ואפילו אכל – that it was definitely forbidden fat, but doubtful that had an olive’s bulk, as for example at the time that he ate it, he thought that it was permitted fat, and afterwards it became known to him that it is forbidden fat, but it is doubtful that it has or does not have an olive’s bulk.
אכל א אאחד מהן – but he thought that it was permitted fat, and afterwards it became known that the one was forbidden fat, but this one doesn’t know which he ate, he brings an uncertain guilt-offering (i.e., a sacrifice brought by someone who is uncertain as to whether he committed a sin that requires a sin offering). But, if at the time of eating he had a doubt, and he willfully acted and ate from doubt, this is willful behavior and he is exempt.
שגג באחת מהן – in thinking that this is wife, and afterwards he was in doubt which of them was, he brings the uncertain guilt-offering.
