לרב יהודה לא קשיא טמא שרץ רחמנא דחייה דכתיב איש איש כי יהיה טמא לנפש מי לא עסקינן שחל שביעי שלו להיות בערב הפסח ואפילו הכי אמר רחמנא לידחי

According to Rav Yehuda’s opinion it is also not difficult, because in his opinion the Torah itself deferred the obligation of one who is ritually impure through contact with a dead creeping animal to the second Pesaḥ, as it is written: “If any man of you or of your generations shall be ritually impure due to a dead body” (Numbers 9:10). Are we not dealing even with a situation in which his seventh day of purification occurs on Passover eve, such that he can be ritually pure by nightfall and therefore he has the same status on that seventh day as one who became impure due to contact with a dead creeping animal? And nonetheless the Torah stated that his obligation shall be deferred. This teaches that anyone who is ritually impure at the time of the slaughtering has his obligation deferred to the second Pesaḥ, even if he would be able to immerse and become pure in time to eat the offering on the first Pesaḥ with the rest of the Jewish people.

תנו רבנן היה עומד חוץ למודיעים ויכול ליכנס בסוסים ובפרדים יכול יהא חייב תלמוד לומר ובדרך לא היה והלה היה בדרך

The Sages taught: If one was standing outside the city of Modi’im and was able to enter Jerusalem on horses or mules but not by walking, I might have thought he would be liable to receive karet for failing to come to Jerusalem and offer the Paschal lamb; therefore, the verse states: “And is not on a journey” (Numbers 9:13). This person was on a distant journey and is therefore exempt.

היה עומד לפנים מן המודיעים ואין יכול ליכנס מפני גמלים וקרונות המעכבות אותו יכול לא יהא חייב תלמוד לומר ובדרך לא היה והרי לא היה בדרך:

On the other hand, if one was standing closer to Jerusalem than Modi’im but was not able to enter due to the camels and carriages that are carrying his family and delaying him, I might have thought he would not be liable for failing to offer the Paschal lamb because he is trying to enter; therefore, the verse states: “And was not on a journey,” and this person was not on a distant journey and is therefore liable. This person could have dismounted and come to Jerusalem on foot, but he wanted to bring his family with him in a carriage and was consequently delayed. One’s liability is determined based on his distance from Jerusalem.

אמר רבא שיתא אלפי פרסי הוי עלמא וסומכא דרקיעא אלפא פרסי חדא גמרא וחדא סברא

The discussion above pertaining to the distance that an average person can walk in a day is based on the assumption that he walks five mil between dawn and sunrise. The Gemara brings support for this assumption. Rava said: The size of the world is six thousand parasangs, and the thickness of the firmament is one thousand parasangs. One of these measurements with regard to the size of the world is a tradition, and one of the measurements is based upon Rava’s own reasoning.

סבר לה כי הא דאמר רבה בר בר חנה אמר רבי יוחנן כמה מהלך אדם בינוני ביום עשר פרסאות מעלות השחר ועד הנץ החמה חמשה מילין משקיעת החמה עד צאת הכוכבים חמשה מילין נמצא עוביו של רקיע אחד מששה ביום

The Gemara explains: Rava holds like that statement which Rabba bar bar Ḥana said that Rabbi Yoḥanan said: How far can an average person walk in a day? One can walk ten parasangs, which are forty mil. This is explained: From dawn until sunrise one can walk a distance of five mil; from sunset until the emergence of the stars one can walk another five mil. Therefore, it is found that the thickness of the firmament is one-sixth of the distance that the sun travels during the day. Between sunrise and sunset, the sun travels a distance of six thousand parasangs during the amount of time an average person can walk thirty mil. During the dawn and twilight periods in the morning and evening, when the sun passes through the thickness of the firmament, an average person can walk five mil, which is one-sixth of the distance he can walk between sunrise and sunset. Consequently, during dawn and twilight the sun must also travel one-sixth of the distance it travels between sunrise and sunset, i.e., one thousand parasangs, which is the thickness of the firmament.

מיתיבי רבי יהודה אומר עוביו של רקיע אחד מעשרה ביום תדע כמה מהלך אדם בינוני ביום עשר פרסאות ומעלות השחר עד הנץ החמה ארבעת מילין משקיעת החמה ועד צאת הכוכבים ארבעת מילין נמצאת עוביו של רקיע אחד מעשרה ביום תיובתא דרבא תיובתא דעולא תיובתא

The Gemara raises an objection from the following baraita: Rabbi Yehuda says: The thickness of the firmament is only one-tenth of the distance that the sun travels during the day. Know that this is true because how far can an average person walk in a day between dawn and the emergence of the stars? One can walk ten parasangs, which are forty mil, and from dawn until sunrise one can walk only four mil, which are one parasang. Therefore, it is found that the thickness of the firmament is only one-tenth of the distance that the sun travels during the day. This is a refutation of the opinion of Rava. Similarly, it is a refutation of the opinion of Ulla, who holds that an average person can walk fifteen mil in half a day, whereas Rabbi Yehuda holds that the average person can walk sixteen mil in half a day. The Gemara concludes: It is indeed a conclusive refutation.

לימא תיהוי תיובתא דרבי יוחנן אמר לך אנא ביממא הוא דאמרי ורבנן הוא דקא טעו דקא חשבן דקדמא וחשוכא

The Gemara suggests: Let us say that this will be a conclusive refutation of the opinion of Rabba bar bar Ḥana, citing Rabbi Yoḥanan, with regard to how far an average person can walk in a day. The Gemara answers: Rabbi Yoḥanan could have said to you: I am speaking about the total distance that an average person can walk in an entire day, but I never specified the distance one can walk during different parts of the day. And it was the Sages Ulla and Rava who erred in interpreting my opinion by saying that one can walk five mil and not four during each intermediate period, because when they calculated five mil before sunrise and after sunset they included the distance walked by people who set out earlier in the morning, before dawn, and by those who continued walking after nightfall.

לימא תיהוי תיובתא דרבי חנינא לא ויאיצו שאני

The Gemara suggests: Let us say it is a conclusive refutation of the opinion of Rabbi Ḥanina, who proved from biblical verses that the distance from Sodom to Zoar is five mil. The angels and Lot walked that distance between dawn and sunrise, which implies that it is only four mil. The Gemara responds: No, that verse states: “The angels hastened Lot,” which indicates that they traveled very quickly. Therefore, hastened is different; because they hurried, they traveled five mil in the time one would normally walk four mil.

תא שמע מצרים היה ארבע מאות פרסה על ארבע מאות פרסה ומצרים אחד מששים בכוש וכוש אחד מששים בעולם ועולם אחד מששים בגן וגן אחד מששים בעדן ועדן אחד מששים בגיהנם נמצא כל העולם כולו ככיסוי קדירה לגיהנם תיובתא

Come and hear a challenge from a baraita to the previous opinion with regard to the size of the world: The size of Egypt was four hundred parasangs by four hundred parasangs, and Egypt is one-sixtieth of the size of Cush, and Cush is one-sixtieth of the world, and the world is one-sixtieth the size of the Garden of Eden, and the Garden of Eden is one-sixtieth of Eden, and Eden is one sixtieth of the size of Gehenna. Therefore, it is found that the entire world is like a pot cover, which is a small part of the total size of the pot, compared to Gehenna. In any event, based upon the sizes of Egypt and Cush, it is apparent that the entire world is larger than six thousand parasangs. This is indeed a conclusive refutation.

תא שמע דתנא דבי אליהו רבי נתן אומר כל הישוב כולו תחת כוכב אחד יושב תדע שהרי אדם נותן עינו בכוכב אחד הולך למזרח עומד כנגדו לארבע רוחות העולם עומד כנגדו מכלל דכל הישוב כולו תחת כוכב אחד יושב תיובתא

Come and hear another challenge: One of the Sages of the school of Eliyahu taught that Rabbi Natan says: The entire settlement, the area of the world that is inhabited, sits under one star. Know that this is correct because when a person focuses his eye on one star, he can travel east as far as he wishes within the settled part of the world and the star remains opposite him in the same place, and he can travel in the four directions of the world and the star remains in place opposite him. By inference, the entire settlement of the world rests under one star; and since so many stars are visible and each one covers an area of the world comparable in size to the entire settled portion of the world, it must be that the world is larger than six thousand parasangs. The Gemara comments that this is indeed a conclusive refutation of Rava’s opinion.

תא שמע עגלה בצפון ועקרב בדרום וכל הישוב כולו אינו יושב אלא בין עגלה לעקרב וכל הישוב כולו אינו הוה אלא שעה אחת ביום שאין חמה נכנסת לישוב אלא שעה אחת ביום

Come and hear another challenge from another baraita, which teaches that the constellation Ursa Major is in the north and the constellation Scorpio is in the south, and the entire settlement sits between Ursa Major and Scorpio, as the relative positions of these two constellations appear to be the same from any location in the settled areas of the world. The ratio of the entire settlement to the world as a whole is comparable to only one hour in a day, as the sun enters the sky above the settlement for only one hour a day while the rest of the day it is outside the settlement.

תדע שבחמש חמה במזרח ובשבע חמה במערב חצי שש וחצי שבע חמה עומדת בראש כל אדם תיובתא

Know that this is correct because at five hours into the day the sun is still in the east, and at seven hours the sun is in the west. During the second half of the sixth hour and the first half of the seventh hour the sun is positioned on top of everyone, as it is in the middle of the sky in every inhabited area during this time.Apparently, the sun travels over the inhabited parts of the world in a single hour while the rest of the day it travels over the uninhabited parts. Therefore, the entire settled portion of the world is equal to one-twelfth of the world. It was established that the settled part of the world itself is several parasangs, so the entire world must be larger than six thousand parasangs. This also serves as a conclusive refutation of Rava’s opinion.

תא שמע דאמר רבן יוחנן בן זכאי מה תשובה השיבתו בת קול לאותו רשע בשעה שאמר אעלה על במתי עב אדמה לעליון יצתה בת קול ואמרה לו רשע בן רשע

Come and hear another challenge, as Rabban Yoḥanan ben Zakkai said: What response did the Divine Voice answer to that wicked man, Nebuchadnezzar, when he said: “I will ascend above the heights of the clouds; I will be like the Most High” (Isaiah 14:14)? A Divine Voice emerged and said to him: Wicked man, son of a wicked man,
