(29) And this shall be to you a law for all time: In the seventh month, on the tenth day of the month, you shall practice self-denial; and you shall do no manner of work, neither the citizen nor the alien who resides among you. (30) For on this day atonement shall be made for you to purify you of all your sins; you shall be pure before Adonai. (31) It shall be a sabbath of complete rest for you, and you shall practice self-denial; it is a law for all time. (32) The priest who has been anointed and ordained to serve as priest in place of his father shall make expiation. He shall put on the linen vestments, the sacral vestments. (33) He shall purge the innermost Shrine; he shall purge the Tent of Meeting and the altar; and he shall make expiation for the priests and for all the people of the congregation. (34) This shall be to you a law for all time: to make atonement for the Israelites for all their sins once a year. And Moses did as Adonai had commanded him.

And there was another incident in which two witnesses came and said: We saw the new moon at its anticipated time, i.e., on the night of the thirtieth day of the previous month; however, on the following night, i.e., the start of the thirty-first, which is often the determinant of a full, thirty-day month, it was not seen. And nevertheless Rabban Gamliel accepted their testimony and established the New Moon on the thirtieth day. Rabbi Dosa ben Horkinas disagreed and said: They are false witnesses; how can witnesses testify that a woman gave birth and the next day her belly is between her teeth, i.e., she is obviously still pregnant? If the new moon was already visible at its anticipated time, how could it not be seen a day later? Rabbi Yehoshua said to him: I see the logic of your statement; the New Moon must be established a day later. Upon hearing that Rabbi Yehoshua had challenged his ruling, Rabban Gamliel sent a message to him: I decree against you that you must appear before me with your staff and with your money on the day on which Yom Kippur occurs according to your calculation; according to my calculation, that day is the eleventh of Tishrei, the day after Yom Kippur. Rabbi Akiva went and foundRabbi Yehoshuadistressed that the head of the Great Sanhedrin was forcing him to desecrate the day that he maintained was Yom Kippur. In an attempt to console him, Rabbi Akivasaid toRabbi Yehoshua: I can learn from a verse that everything that Rabban Gamliel did in sanctifying the month is done, i.e., it is valid. As it is stated: “These are the appointed seasons of the Lord, sacred convocations, which you shall proclaim in their season” (Leviticus 23:4). This verse indicates that whether you have proclaimed them at their proper time or whether you have declared them not at their proper time, I have only these Festivals as established by the representatives of the Jewish people. Rabbi Yehoshua then came to Rabbi Dosa ben Horkinas, who said to him: If we come to debate and question the rulings of the court of Rabban Gamliel, we must debate and question the rulings of every court that has stood from the days of Moses until now. As it is stated: “Then Moses went up, and Aaron, Nadav and Avihu, and seventy of the Elders of Israel” (Exodus 24:9). But why were the names of these seventy Elders not specified? Rather, this comes to teach that every set of three judges that stands as a court over the Jewish people has the same status as the court of Moses. Since it is not revealed who sat on that court, apparently it is enough that they were official judges in a Jewish court. When Rabbi Yehoshua heard that even Rabbi Dosa ben Horkinas maintained that they must submit to Rabban Gamliel’s decision, he took his staff and his money in his hand, and went to Yavne to Rabban Gamliel on the day on which Yom Kippur occurred according to his own calculation. Upon seeing him, Rabban Gamliel stood up and kissed him on his head. He said to him: Come in peace, my teacher and my student. You are my teacher in wisdom, as Rabbi Yehoshua was wiser than anyone else in his generation, and you are my student, as you accepted my statement, despite your disagreement.

Rav Huna said: One who was walking along the way or in the desert, and he does not know when Shabbat occurs, he counts six days from the day that he realized that he lost track of Shabbat and then observes one day as Shabbat. Ḥiyya bar Rav says: He first observes one day as Shabbat and then he counts six weekdays. The Gemara explains: With regard to what do they disagree? One Sage, Rav Huna, held: It is like the creation of the world, weekdays followed by Shabbat. And one Sage, Ḥiyya bar Rav, held: It is like Adam, the first man, who was created on the sixth day.

The person who lost track of Shabbat and treats one day a week as Shabbat, each day he makes enough food to sustain himself, except for that day which he designated as Shabbat. The Gemara asks: And on that day let him die? Rather, it means that the day before he makes twice the amount of food that he prepared on the other days to sustain him for that day and the following day. The Gemara asks: And perhaps the day before was actually Shabbat? In that case, not only did he perform labor on Shabbat, but he also performed labor on Shabbat in preparation for a weekday. Rather, on each and every day he makes enough food to sustain himself for that day, including on that day that he designated as Shabbat. And if you ask: And how is that day which he designated as Shabbat distinguishable from the rest? It is distinguishable by means of the kiddush and the havdala that he recites on that day.

Rava said: If he had partial knowledge of the day on which he left, i.e., he does not recall what day of the week it was but he does recall the number of days that passed since he left, every week he can perform labor throughout the day of his departure, since he certainly did not leave his house on Shabbat. The Gemara asks: That is obvious, and what novel element was introduced here? The Gemara answers: Lest you say, since he did not leave on Shabbat, he also did not leave on Friday, and this person, even if he left on Thursday, should be permitted to perform labor for two days, the eighth day and the ninth day from his departure, the same day of the week that he left and the following day. Therefore, Rava teaches us that at times one finds a convoy and happens to leave on a journey even on Friday. Therefore, he is not permitted to perform labor on the day of the week following the day of his departure.

§ The mishna further taught that if she married by permission of the court she must leave him, but she is exempt from bringing a sin-offering. On this issue, Ze’eiri said: The mishna is not accepted, and this is derived from what was taught in the study hall, as it was taught in a baraita in the study hall: If the court ruled that the sun had set at the conclusion of Shabbat, which means it is permitted to perform labor, and later the sun shone, this is not a ruling for which the court is to blame, but an error. Consequently, the court does not have to bring an offering for the unwitting communal sin. Rather, each individual is liable to bring a separate offering. Here too, although the woman married with the consent of the court, they did not issue a mistaken ruling of halakha but simply erred with regard to the facts. She is therefore an unwitting sinner and is liable to bring an offering.

R. Simon said: When the Holy Blessed One decided to make the first person, the ministering angels formed themselves into groups and parties, some of them saying: “Let him be created!” and others saying, “Do not let him be created!” as it is said: “Lovingkindness and Truth meet, Justice and Peace kiss” (Ps. 85:11).
Lovingkindness says: “Let him be created, because he will do acts of love,”
and Truth says, “Do not let him be created, because he is all lies.”
Justice says, “Let him be created, for he will do acts of justice,”
and Peace says, “Do not let him be created, for he is all strife.”
What did the Holy Blessed One do? He took Truth and cast it to the earth (to the ground), as it is written: “It hurled truth to the ground” (Daniel 8:12).
The angels said to the Holy Blessed One: Master of the Universe, do you disgrace your own seal? Raise up Truth from the earth/ground, as it is written: “Truth from the earth will spring up” (Ps. 85:12)
R. Huna the Elder of Sepphoris said: As the ministering angels were arguing and disputing with each other, God created him [Adam], and said to them: “Why are you arguing! Adam has already been created.”
