והאי יתנו עידיהם ויצדקו בעובדי כוכבים כתיב הא בישראל כתיב דאמר ריב"ל כל מצות שישראל עושין בעולם הזה באות ומעידות להם לעוה"ב שנאמר יתנו עידיהם ויצדקו אלו ישראל ישמעו ויאמרו אמת אלו עובדי כוכבים
The Gemara asks: But is this verse: “Let them bring their witnesses that they may be justified,” written with regard to the nations of the world? Isn’t it written with regard to the Jewish people? As Rabbi Yehoshua ben Levi says: All the mitzvot that the Jews perform in this world will come and bear witness for them in the World-to-Come, as it is stated: “Let them bring their witnesses that they may be justified.” These are the Jews, as their good deeds bear witness for them and demonstrate their righteousness. When the verse states: “And let them hear, and say: It is truth” (Isaiah 43:9), these are the nations of the world, who will admit to the righteousness of the Jews.
דרש ר' חנינא בר פפא ואיתימא ר' שמלאי לעתיד לבא מביא הקדוש ברוך הוא ס"ת [ומניחו] בחיקו ואומר למי שעסק בה יבא ויטול שכרו
§ The Gemara cites homiletic interpretations of the verse that was discussed earlier: “All the nations are gathered together, and let the peoples be assembled; who among them can declare this, and announce to us former matters? Let them bring their witnesses, that they may be justified; and let them hear, and say: It is truth” (Isaiah 43:9). Rabbi Ḥanina bar Pappa taught, and some say that it was Rabbi Simlai who taught: In the future, the Holy One, Blessed be He, will bring a Torah scroll and place it in His lap and say: Anyone who engaged in its study should come and take his reward.
אמר להם הקב"ה במאי עסקתם אומרים לפניו רבש"ע הרבה שווקים תקנינו הרבה מרחצאות עשינו הרבה כסף וזהב הרבינו וכולם לא עשינו אלא בשביל ישראל כדי שיתעסקו בתורה אמר להם הקב"ה שוטים שבעולם כל מה שעשיתם לצורך עצמכם עשיתם תקנתם שווקים להושיב בהן זונות מרחצאות לעדן בהן עצמכם כסף וזהב שלי הוא שנאמר (חגי ב, ח) לי הכסף ולי הזהב נאם ה' צבאות
The Gemara returns to its narration of the future judgment. First, the members of the Roman Empire enter. The Holy One, Blessed be He, says to them: With what did you occupy yourselves? They say before Him in response: Master of the Universe, we have established many marketplaces, we have built many bathhouses, and we have increased much silver and gold. And we did all of this only for the sake of the Jewish people, so that they would be free to engage in Torah study. The Holy One, Blessed be He, says to them: Fools of the world! Are you attempting to deceive Me? Everything that you did, you did for your own needs. You established marketplaces to place prostitutes in them; you built bathhouses for your own enjoyment; and as for the silver and gold that you claim to have increased, it is Mine, as it is stated: “Mine is the silver, and Mine the gold, said the Lord of hosts” (Haggai 2:8).
אומרים לפניו רבש"ע כלום נתת לנו ולא קיבלנוה ומי מצי למימר הכי והכתי' (דברים לג, ב) ויאמר ה' מסיני בא וזרח משעיר למו וכתיב (חבקוק ג, ג) אלוה מתימן יבוא וגו' מאי בעי בשעיר ומאי בעי בפארן א"ר יוחנן מלמד שהחזירה הקב"ה על כל אומה ולשון ולא קבלוה עד שבא אצל ישראל וקבלוה
The nations will say before God: Master of the Universe, did You give us the Torah and we did not accept it? Since we never received the Torah, why are we being judged for not fulfilling its mitzvot? The Gemara asks: And can one say that they were never offered the Torah? But isn’t it written in the description of the giving of the Torah: “And he said: The Lord came from Sinai, and rose from Seir unto them” (Deuteronomy 33:2), and it is written: “God comes from Teman, and the Holy One from mount Paran” (Habakkuk 3:3). And the Sages asked: What did God require in Seir and what did He require in Paran? The Torah was not given in those locations. And Rabbi Yoḥanan says: This teaches that the Holy One, Blessed be He, took the Torah around to every nation and those who speak every language, such as the Edomites in Seir and the Ishmaelites in Paran, but they did not accept it, until He came to the Jewish people and they accepted it. If the other nations all rejected the Torah, how can they excuse themselves by claiming that it was never offered to them?
אלא הכי אמרי כלום קיבלנוה ולא קיימנוה ועל דא תברתהון אמאי לא קבלתוה אלא כך אומרים לפניו רבש"ע כלום כפית עלינו הר כגיגית ולא קבלנוה כמו שעשית לישראל דכתיב (שמות יט, יז) ויתיצבו בתחתית ההר ואמר רב דימי בר חמא מלמד שכפה הקב"ה הר כגיגית על ישראל ואמר להם אם אתם מקבלין את התורה מוטב ואם לאו שם תהא קבורתכם מיד אומר להם הקב"ה הראשונות ישמיעונו שנא' (ישעיהו מג, ט) וראשונות ישמיענו שבע מצות שקיבלתם היכן קיימתם
Rather, this is what they say: Did we accept the Torah and then not fulfill its mitzvot? The Gemara asks: But this itself serves as the refutation of their own claim, as one can respond: Why didn’t you accept it? Rather, this is what the nations of the world say before Him: Master of the Universe, did You overturn the mountain above us like a basin, and we still did not accept the Torah, as You did for the Jewish people? The Gemara provides the background for this claim: As it is written: “And they stood at the nether part of the mount” (Exodus 19:17), and Rav Dimi bar Ḥama says: The verse teaches that the Holy One, Blessed be He, overturned the mountain, i.e., Mount Sinai, above the Jews like a basin, and He said to them: If you accept the Torah, excellent, and if not, there, under the mountain, will be your burial. The nations of the world will claim that they too could have been coerced to accept the Torah. Immediately, the Holy One, Blessed be He, says to them: The first mitzvot will let us hear the truth, as it is stated in the continuation of the same verse under discussion: “And announce to us the first things” (Isaiah 43:9). With regard to the seven Noahide mitzvot that preceded the giving of the Torah that even you accepted, where is the proof that you fulfilled them?
ומנלן דלא קיימום דתני רב יוסף (חבקוק ג, ו) עמד וימודד ארץ ראה ויתר גוים מאי ראה ראה ז' מצות שקבלו עליהן בני נח ולא קיימום כיון שלא קיימום עמד והתירן להן איתגורי איתגור א"כ מצינו חוטא נשכר אמר מר בריה דרבינא לומר שאף על פי שמקיימין אותן אין מקבלין עליהם שכר
The Gemara asks: And from where do we derive that they did not fulfill them? As Rav Yosef teaches in explanation of the verse: “He stands, and shakes the earth, He sees, and makes the nations tremble [vayater]” (Habakkuk 3:6): What did God see? He saw the seven mitzvot that the descendants of Noah accepted upon themselves, and He saw that they did not fulfill them. Since they did not fulfill them, He arose and nullified for them [vehitiran] the command to heed these mitzvot. The Gemara asks: Do they gain from not obeying, as they are now released from the obligation to fulfill these mitzvot? If so, we find that a sinner profits from his transgression. Mar, son of Ravina, said: This serves to say that even if they fulfill the seven Noahide mitzvot they do not receive a reward for their fulfilment.
ולא והתניא היה רבי מאיר אומר מנין שאפילו עובד כוכבים ועוסק בתורה שהוא ככהן גדול תלמוד לומר (ויקרא יח, ה) אשר יעשה אותם האדם וחי בהם כהנים לוים וישראלים לא נאמר אלא האדם הא למדת שאפילו עובד כוכבים ועוסק בתורה הרי הוא ככהן גדול אלא לומר לך שאין מקבלין עליהם שכר כמצווה ועושה אלא כמי שאינו מצווה ועושה דאמר ר' חנינא גדול המצווה ועושה יותר משאינו מצווה ועושה
The Gemara asks: And are they not rewarded for fulfilling those mitzvot? But isn’t it taught in a baraita that Rabbi Meir would say: From where is it derived that even a gentile who engages in Torah study is considered like a High Priest? The verse states: “You shall therefore keep My statutes and My ordinances, which if a person do, and shall live by them” (Leviticus 18:5). It is not stated: Priests, Levites, and Israelites, but rather the general term “person.” From here you learn that even a gentile who engages in the study of Torah is like a High Priest. This demonstrates that gentiles are rewarded for fulfilling mitzvot, despite the fact that they are not commanded to do so. Rather, the verse serves to tell you that they do not receive as great a reward for their fulfillment as one who is commanded and performs a mitzva. Rather, they receive a lesser reward, like that of one who is not commanded and still performs a mitzva. As Rabbi Ḥanina says: Greater is one who is commanded to do a mitzva and performs it than one who is not commanded and performs it.
איכא דמתני להא דרבי יצחק אהא דתניא רבי יוסי אומר לעתיד לבא באין עובדי כוכבים ומתגיירין ומי מקבלינן מינייהו והתניא אין מקבלין גרים לימות המשיח כיוצא בו לא קבלו גרים לא בימי דוד ולא בימי שלמה
There are those who teach that which Rabbi Yitzḥak subsequently said with regard to this matter, as it is taught in a baraita that Rabbi Yosei says: In the future, the nations of the world will come and convert. The Gemara asks: And do we accept them as converts at that time? But isn’t it taught in another baraita: The court does not accept converts in the days of the Messiah; similarly, they did not accept converts either in the days of David or in the days of Solomon, due to a concern that these people wanted to convert for ulterior motives, because the Jewish people were mighty and respected?
איני והא אמר רב יהודה אמר רב שתים עשרה שעות הוי היום שלש הראשונות הקב"ה יושב ועוסק בתורה שניות יושב ודן את כל העולם כולו כיון שרואה שנתחייב עולם כלייה עומד מכסא הדין ויושב על כסא רחמים
The Gemara asks: Is that so? Is there is no other making sport for the Holy One, Blessed be He? But doesn’t Rav Yehuda say that Rav says: There are twelve hours in the day. During the first three, the Holy One, Blessed be He, sits and engages in Torah study. During the second three hours, He sits and judges the entire world. Once He sees that the world has rendered itself liable to destruction, He arises from the throne of judgment and sits on the throne of mercy, and the world is not destroyed.
ברביעיות מאי עביד יושב ומלמד תינוקות של בית רבן תורה שנאמר (ישעיהו כח, ט) את מי יורה דעה ואת מי יבין שמועה גמולי מחלב עתיקי משדים למי יורה דעה ולמי יבין שמועה לגמולי מחלב ולעתיקי משדים
The Gemara asks: If God no longer makes sport, what does He now do during the fourth three-hour period of the day? The Gemara answers: He sits and teaches Torah to schoolchildren, as it is stated: “Whom shall one teach knowledge? And whom shall one make to understand the message? Them that are weaned from the milk, them that are drawn from the breasts” (Isaiah 28:9). The verse is interpreted in the following manner: To whom does God teach knowledge, and to whom does He make to understand the message? To those who are just weaned from the milk and to those who are drawn from the breasts, i.e., children only recently weaned from nursing.
ואמר רבי יהושע בן לוי כל מצות שישראל עושין בעולם הזה באות וטורפות אותם לעובדי כוכבים לעולם הבא על פניהם שנאמר (דברים ד, ו) ושמרתם ועשיתם כי היא חכמתכם ובינתכם לעיני העמים נגד העמים לא נאמר אלא לעיני העמים מלמד שבאות וטורפות לעובדי כוכבים על פניהם לעוה"ב
And Rabbi Yehoshua ben Levi says: All of the mitzvot that the Jewish people perform in this world will come and strike the faces of the nations of the world in the World-to-Come, as it is stated: “Observe therefore and do them; for this is your wisdom and your understanding in the eyes of the nations” (Deuteronomy 4:6). It is not stated: Before the nations; rather, the verse states: “In the eyes of the nations,” which taken literally teaches that they will come and strike the faces of the nations of the world in the World-to-Come.
וא"ר יהושע בן לוי לא עשו ישראל את העגל אלא ליתן פתחון פה לבעלי תשובה שנאמר (דברים ה, כה) מי יתן והיה לבבם זה להם ליראה אותי כל הימים וגו'
And Rabbi Yehoshua ben Levi says: The Jewish people fashioned the Golden Calf (see Exodus, chapter 32) only to give a claim to penitents, as it is stated after the revelation at Sinai: “Who would give that they had such a heart as this always, to fear Me, and keep all My commandments, that it might be good for them, and with their children forever” (Deuteronomy 5:25). If the nation was truly at such a lofty spiritual state, how could they worship the Golden Calf? Rather, their sin occurred so that it would be made clear that one can repent for any sin, as even a sin as severe as the Golden Calf was forgiven.
ר"א אומר קשורה בו ככלב שנאמר (בראשית לט, י) ולא שמע אליה לשכב אצלה להיות עמה לשכב אצלה בעוה"ז להיות עמה בעוה"ב
Rabbi Elazar says: The transgression is tied to him like a dog and does not leave him, as it is stated with regard to Joseph and Potiphar’s wife: “And he did not listen to her, to lie by her, or to be with her” (Genesis 39:10). This teaches that Joseph refused “to lie by her” in this world, which would have meant that he would have had “to be with her” in the World-to-Come.
והאמר ר"ל מאי דכתיב (בראשית ה, א) זה ספר תולדות אדם וגו' וכי ספר היה לו לאדם הראשון מלמד שהראה לו הקב"ה לאדם הראשון דור דור ודורשיו דור דור וחכמיו דור דור ופרנסיו כיון שהגיע לדורו של ר"ע שמח בתורתו ונתעצב במיתתו אמר (תהלים קלט, יז) ולי מה יקרו רעיך אל [וגו']
The Gemara raises a further difficulty: But doesn’t Reish Lakish say: What is the meaning of that which is written: “This is the book of the generations of Adam, in the day that God created man” (Genesis 5:1)? Did Adam the first man have a book? Rather, the verse teaches that the Holy One, Blessed be He, showed Adam, the first man, every generation and its expositors, every generation and its Sages, and every generation and its leaders. When Adam arrived at the generation of Rabbi Akiva, he rejoiced in his Torah and was saddened by his death, as Rabbi Akiva was tortured and murdered. Adam said: “How weighty also are Your thoughts to me, O God! How great is the sum of them” (Psalms 139:17). It is evident from here that the Jews were destined to bear future generations from the beginning of time.
על תנאי ומי כתיבי קראי על תנאי אין דהכי אמר רבי שמעון בן לקיש מאי דכתיב (בראשית א, לא) ויהי ערב ויהי בקר יום הששי מלמד שהתנה הקב"ה עם מעשה בראשית ואמר אם מקבלין ישראל את התורה מוטב ואם לאו אחזיר אתכם לתוהו ובוהו
The Gemara answers: These passages were written conditionally, i.e., if the Jewish people were to sin and not become like angels, those halakhot would take effect. The Gemara asks: And are verses written conditionally in this manner? The Gemara answers: Yes, as this is what Rabbi Shimon ben Lakish says: What is the meaning of that which is written: “And there was evening and there was morning, the sixth day” (Genesis 1:31)? This teaches that the Holy One, Blessed be He, established a condition with the acts of Creation, and He said: If the Jewish people accept the Torah at the revelation at Sinai, all is well and the world will continue to exist. But if they do not accept it, I will return you to the primordial state of chaos and disorder.
ות"ק נמי הכתיב אכן כאדם תמותון מאי מיתה עניות דאמר מר ארבעה חשובים כמתים אלו הן עני סומא ומצורע ומי שאין לו בנים
The Gemara inquires: And according to the first tanna as well, isn’t it written: “Yet you shall die like a man,” which indicates that their mortality was decreed only due to the sin of the Golden Calf? The Gemara answers: What is meant by death? It means poverty. As the Master said: Four are considered as though they were dead: These are a pauper, a blind person, a leper, and one who has no children.
משלחי רגל השור והחמור תנא דבי אליהו לעולם ישים אדם עצמו על דברי תורה כשור לעול וכחמור למשאוי:
With regard to the continuation of the verse: “That send forth freely the feet of the ox and the donkey,” one of the Sages of the school of Eliyahu taught: A person should always make himself subjugated to matters of Torah like an ox to a yoke and like a donkey to a burden.
תנא דבי אליהו ישים עצמו על ד"ת כשור לעול וכחמור למשאוי. פירוש כי בזה יבטלו רגל השור והחמור שהוא היצה"ר:
איבעיא להו משום הרווחה או דלמא משום (ויקרא יט, יד) ולפני עור לא תתן מכשול למאי נפקא מינה דאית ליה בהמה לדידיה אי אמרת משום הרווחה הא קא מרווח ליה אי אמרת משום עור לא תתן מכשול הא אית ליה לדידיה
§ A dilemma was raised before the Sages: Is the reason for the prohibition against conducting business with gentiles in the days preceding their festivals because the gentile might profit, which will bring him joy, and he will subsequently give thanks to his idol on his festival? Or perhaps it is because this is a violation of the prohibition: “And you shall not put a stumbling block before the blind” (Leviticus 19:14), as one who sells an animal to a gentile thereby aids him in engaging in prohibited idol worship. The Gemara explains: What is the practical difference between the two options? The practical difference is in a situation where the gentile already has an animal of his own. If you say that the reason for the prohibition is because he might profit, here too the Jew causes him to profit. But if you say that the reason for the prohibition is due to the prohibition: “You shall not put a stumbling block before the blind,” since the gentile has his own animal, the Jew is not helping him sin.
וכי אית ליה לא עבר משום עור לא תתן מכשול והתניא אמר רבי נתן מנין שלא יושיט אדם כוס של יין לנזיר ואבר מן החי לבני נח ת"ל (ויקרא יט, יד) ולפני עור לא תתן מכשול והא הכא דכי לא יהבינן ליה שקלי איהו וקעבר משום לפני עור לא תתן מכשול
The Gemara challenges: And even if he already has his own animal, does not one who assists him transgress due to the command: “You shall not put a stumbling block before the blind”? But isn’t it taught in a baraita that Rabbi Natan said: From where is it derived that a person may not extend a cup of wine to a nazirite, who is prohibited from drinking wine, and that he may not extend a limb severed from a living animal to descendants of Noah? The verse states: “And you shall not put a stumbling block before the blind” (Leviticus 19:14). But here, in both cases, if one does not give it to him, he can take it himself, and yet the one who provides it to him transgresses due to the prohibition: “You shall not put a stumbling block before the blind.”
איבעיא להו משום הרווחה או דלמא משום (ויקרא יט, יד) ולפני עור לא תתן מכשול למאי נפקא מינה דאית ליה בהמה לדידיה אי אמרת משום הרווחה הא קא מרווח ליה אי אמרת משום עור לא תתן מכשול הא אית ליה לדידיה וכי אית ליה לא עבר משום עור לא תתן מכשול והתניא אמר רבי נתן מנין שלא יושיט אדם כוס של יין לנזיר ואבר מן החי לבני נח ת"ל (ויקרא יט, יד) ולפני עור לא תתן מכשול והא הכא דכי לא יהבינן ליה שקלי איהו וקעבר משום לפני עור לא תתן מכשול הב"ע דקאי בתרי עברי נהרא דיקא נמי דקתני לא יושיט ולא קתני לא יתן ש"מ
§ A dilemma was raised before the Sages: Is the reason for the prohibition against conducting business with gentiles in the days preceding their festivals because the gentile might profit, which will bring him joy, and he will subsequently give thanks to his idol on his festival? Or perhaps it is because this is a violation of the prohibition: “And you shall not put a stumbling block before the blind” (Leviticus 19:14), as one who sells an animal to a gentile thereby aids him in engaging in prohibited idol worship.

But here, in both cases, if one does not give it to him, he can take it himself, and yet the one who provides it to him transgresses due to the prohibition: “You shall not put a stumbling block before the blind.” The Gemara answers: Here we are dealing with a case where they are standing on the two sides of a river, and therefore the recipient could not have taken it himself. Since his help was instrumental, the one who conveyed the item has violated the prohibition of putting a stumbling block before the blind. The Gemara adds: The language of the baraita is also precise, as it teaches: A person may not extend, and it does not teach: One may not give. Learn from the usage of the term extend that the baraita is referring to one located on one side of a river, who extends the item to the one on the other side.
להשאילן ולשאול מהן כו': בשלמא להשאילן דקא מרווח להו אבל לשאול מהן מעוטי קא ממעט להו אמר אביי גזרה לשאול מהן אטו להשאילן רבא אמר כולה משום דאזיל ומודה הוא:
§ The mishna teaches that it is prohibited to lend them items and to borrow items from them during the three days preceding their festivals. The Gemara asks: Granted, it is prohibited to lend the items to them, as this causes them to have a profit. But why is it prohibited to borrow the items from them during this period? Doesn’t this serve to reduce for them the property they possess during the festival? Abaye said: The Sages issued a decree that it is prohibited to borrow the items from them due to the concern that he might come to lend the items to them. Rava said: All of it, lending and borrowing, is prohibited for the same reason, as in either situation the gentile might go and give thanks to his idol, as he will be pleased that the Jew was forced to borrow the items from him.
הלכתא כרבי יהושע הא דאמרן כר' יהודה דתניא הנותן צמר לצבע לצבוע לו אדום וצבעו שחור שחור וצבעו אדום ר"מ אומר נותן לו דמי צמרו רבי יהודה אומר אם השבח יתר על היציאה נותן לו את היציאה ואם היציאה יתירה על השבח נותן לו את השבח
The Gemara explains: As for the statement that the halakha is in accordance with the opinion of Rabbi Yehoshua ben Korḥa, this is referring to that which we said with regard to collecting a loan by oral agreement from gentiles during the days preceding their festivals. As for the statement that the halakha is in accordance with the opinion of Rabbi Yehuda, this is as it is taught in a mishna (Bava Kamma 100b): In the case of one who gives wool to a dyer to dye it red for him and instead he dyed it black, or one who gives wool to a dyer to dye it black and instead he dyed it red, Rabbi Meir says: The dyer gives the owner of the wool the value of his wool. Since the dyer deviated from the owner’s wishes, he is considered akin to a robber who acquires the stolen item by changing it. Therefore, like a robber he keeps the changed item and pays the owner its original value. Rabbi Yehuda says: The dyer does not acquire the wool; rather, the owner of the wool must reimburse the dyer for his expenses, without losing out himself. If the value of the enhancement, i.e., the enhanced value of the wool, exceeds the dyer’s expenses, the owner of the wool gives the dyer the expenses. And if the expenses exceed the enhancement, he gives him the value of the enhancement.
ת"ר לא יאמר אדם לחבירו הנראה שתעמוד עמי לערב רבי יהושע בן קרחה אומר אומר אדם לחבירו הנראה שתעמוד עמי לערב אמר רבה בר בר חנה א"ר יוחנן הלכתא כרבי יהושע בן קרחה
§ The Gemara discusses other halakhot that are in accordance with the opinion of Rabbi Yehoshua ben Korḥa. The Sages taught: A person may not say to another on Shabbat: Does it seem that you will join me this evening? This is prohibited, as the speaker is hinting that he would like to hire him for labor after the conclusion of Shabbat. Rabbi Yehoshua ben Korḥa says: A person may say to another on Shabbat: Does it seem that you will join me this evening? In this case, he is not asking him explicitly. Rabba bar bar Ḥana says that Rabbi Yoḥanan says: The halakha is in accordance with the opinion of Rabbi Yehoshua ben Korḥa.
ת"ר הנשאל לחכם וטימא לא ישאל לחכם ויטהר לחכם ואסר לא ישאל לחכם ויתיר
The Sages taught: In the case of one who asks a question of a Sage with regard to an issue of ritual impurity and the Sage rules that the item is impure, he may not ask the same question of another Sage and have him rule that it is pure. Similarly, in the case of one who asks a Sage a halakhic question and he deems it forbidden, he may not ask the question of another Sage and have him deem it permitted.
גמ׳ אמר רב תחליפא בר אבדימי אמר שמואל יום א' לדברי ר' ישמעאל לעולם אסור:
GEMARA: Rav Taḥlifa bar Avdimi says that Shmuel says: With regard to a Christian, according to the statement of Rabbi Yishmael it is always prohibited for a Jew to engage in business with him. Since his festival takes place every Sunday and the three days before and after Sunday constitute the entire week, one cannot engage in business with a Christian on any day of the week.
אמר ליה אם אדם משים עצמו כמדבר זה שהכל דשין בו תורה ניתנה לו במתנה וכיון שניתנה לו במתנה נחלו אל שנאמר וממתנה נחליאל וכיון שנחלו אל עולה לגדולה שנאמר ומנחליאל במות
Rava said to him: If a person makes himself humble like this wilderness, which is open to all and upon which everyone treads, the Torah will be given to him as a gift [mattana]. And once it is given to him as a gift, he inherits it [neḥalo] and God [El] makes it His inheritance, as it is stated: “And from Mattanah to Nahaliel.” And once God has made it His inheritance, he rises to greatness, as it is stated: “And from Nahaliel to Bamoth,” which means heights.
