That is that He commanded us to honor the sages, to rise in front of them and to glorify them. And that is His, may He be exalted, saying, "In the presence of the elderly you shall rise and you shall respect an elder" (Leviticus 19:32). And the language of the Sifra is, "Rising that has honor." And the regulations of this commandment have already been explained in the first chapter of Kiddushin. And you should know that even if this commandment is obligatory for all people in general - meaning to honor sages, and even [towards] a sage that is one's equal in wisdom, like they explained in their saying (Bava Metzia 33a), "The Torah scholars in Babylonia would stand up for one another" - you should know that there are additional [obligations] of honor for the student. And that is because the honor a student is obligated towards his teacher is much more than the honor due to a sage [in general]. And along with the honor, he is obligated to fear him. For they have already explained that the law of his teacher upon him is like the law of his father, whom Scripture has obligated him to honor and fear. And they already said (Sanhedrin 5b) that it is not permissible to disagree with his rabbi - meaning a disagreement that breaks with his instruction and legal decision, such that he relies upon his [own] wisdom and teaches or decides and instructs, unless [his teacher] gives him permission. And it is not permissible to quarrel with him, nor to get upset with him. And he may not suspect him regarding his actions or words with various suspicions, as it is possible that this was not [his teacher's] intention. And in the chapter [entitled] Chelek (Sanhedrin 110a), they said, "Anyone who disagrees with his teacher is as if he disagrees with the Divine Presence, as it is stated (Numbers 26:9), 'when they strove against the Lord.' And anyone who argues with his teacher is as if he argues with the Holy One, blessed be He, as it is stated (Numbers 20:13), 'These are the waters of Meribah, [where the children of Israel quarreled with the Lord].' And anyone who gets upset with his teacher is as if he is upset with the Divine Presence, as it is stated (Exodus 16:8), 'Your complaints are not against us, but against the Lord.' And anyone who suspects his teacher is as if he suspects the Divine Presence, as it is stated (Numbers 21:5), 'And the people spoke against God, and against Moses.'" And this is completely clear, since the disagreement of Korach and the argument of the Children of Israel - and their complaint and their accusation and their suspicion - was with Moshe, who was the teacher of all of Israel; but Scripture put all of these matters of theirs towards God. And in the explanation (Avot 4:12), they said, "The fear of your teacher is like the fear of the Heavens." And [this fear] is all deduced and proved from Scripture's commanding [us] to honor parents and sages, as is explained in many places in the Talmud - but that [does not make] it a separate commandement. And understand this. (See Parashat Kedoshim; Mishneh Torah, Torah Study).

§ The Sages taught with regard to the verse: “Before the hoary head you shall stand and you shall revere the face of an elder, and you shall fear your God” (Leviticus 19:32): One might have thought that it is obligatory to stand before a simple [ashmai] elder. Therefore, the verse states: “elder,” and an “elder” means nothing other than a wise man, as it is stated: “Gather unto Me seventy men of the Elders of Israel, whom you know to be the Elders of the people” (Numbers 11:16). Rabbi Yosei HaGelili says: An “elder [zaken]” means nothing other than one who has acquired wisdom. He interprets the word zaken as a contraction of the phrase zeh kanna, meaning: This one has acquired. Elsewhere the word kanna is used in reference to wisdom, as it is stated that wisdom says: “The Lord acquired me [kanani] at the beginning of His way” (Proverbs 8:22).

You shall rise before the aged and show deference to the old; you shall fear your God: I am יהוה.

In the presence of the elderly [one who understands the Torah] you shall rise and you shall respect an elder; you shall have fear of your God, I am Adonoy.

The baraita continues: Rabbi Shimon ben Elazar says: From where is it derived that an elder should not trouble others to honor him? The verse states: “And you shall revere the face of an elder, and you shall fear your God.” The phrase “an elder, and you shall fear,” read by itself, without the rest of the verse, indicates that an elder is also commanded to fear God, and not purposefully act in a manner to cause others to have to honor him. In conclusion, the baraita cites another opinion. Isi ben Yehuda says that the verse: “Before the hoary head you shall stand,” indicates that even any person of hoary head is included in this mitzva, not only a Sage. The Gemara analyzes this baraita. Apparently the opinion of Rabbi Yosei HaGelili is the same as that of the first tanna, as they both say that an elder is a Torah scholar. What does Rabbi Yosei HaGelili add? The Gemara answers: There is a difference between them with regard to one who is young and wise. The first tanna maintains: One who is young and wise is not considered an elder, as the mitzva applies only to one who is both elderly and wise. Rabbi Yosei HaGelili maintains: It is even a mitzva to honor one who is young and wise. According to Rabbi Yosei HaGelili, the mitzva is not referring to old age at all, but only to wisdom. The Gemara asks: What is the reasoning of Rabbi Yosei HaGelili? He could have said to you that if it enters your mind to explain as the first tanna says, that for the obligation to honor another to be in effect that person must be both elderly and wise, if so, let the Merciful One write: Before the hoary head of an elder you shall stand and you shall revere. What is the difference between the two terms “hoary head” and “elder,” that the Merciful One separates them? This serves to say that this term is not the same as that one, and that term is not the same as this one, i.e., an elder is not required to have a hoary head. Learn from the verse that even one who is young and wise is called an elder. And the first tanna would say that the verse is written this way because the Torah wants to juxtapose “elder” with “and you shall fear,” in accordance with Rabbi Shimon ben Elazar’s statement above that an elder should not trouble others to honor him. The Gemara asks: And what is the reasoning of the first tanna? Why does he maintain that one is obligated to stand only before an elder, wise man? The Gemara answers: The first tanna maintains that if it enters your mind to explain as Rabbi Yosei HaGelili says, let the Merciful One write: Before the hoary head of an elder you shall stand and revere; you shall stand and revere the face of an elder. From the fact that the Merciful One did not write this and thereby divide the two concepts, learn from it that “elder” and “hoary head” are together referring to one type of person.

§ It was stated previously that Isi ben Yehuda says that as the verse states: “Before the hoary head you shall stand,” it indicates that even anyone of hoary head is included, not only a Torah scholar. Rabbi Yoḥanan said: The halakha is in accordance with the opinion of Isi ben Yehuda. The Gemara relates: Rabbi Yoḥanan himself would stand before Aramean, i.e., gentile, elders. He said: How many experiences [harpatkei] have occurred to these individuals. It is appropriate to honor them, due to the wisdom they have garnered from their long lives. Rava would not stand before them, but he displayed reverence to them.

We should stand before an old man of exceedingly advanced age, even if he is not a sage. Even a sage who is young is obligated to stand before an old man of exceedingly advanced age. Nevertheless, he need not rise to his full height, and need only show some token of respect.Even an old gentile should be addressed with words of respect, and a hand should be extended to support him, as [Leviticus 19:32] states: "Stand up before a white-haired [man]." Every white-haired man is included therein.

It is a mitzvah to respect every Torah sage, even if he is not one's teacher, as [Leviticus 19:32] states: "Stand up before a white-haired [man] and respect an elder." [The word] zakein, [translated as "elder," alludes to the Hebrew words meaning] "one who has acquired wisdom."When is one obligated to stand before him? When he approaches within four cubits of him until he passes him.

It is not proper for a sage to trouble the people and position himself before them so that they will have to stand for him. Rather, he should take shortcuts and have the intent that they should not see him, so that he will not trouble them to stand. The Sages would take circular routes through the outskirts [of their cities], where people who recognize them would not be found, in order not to trouble them.

One who sees a sage need not stand in deference to him until he reaches within four cubits of him; once he has passed, he may sit.Should one see the av beit din, one should stand in deference to him from the time he sees him - as far away as he can see. He may not sit until he has passed four cubits beyond him.Should one see the nasi, one should stand in deference to him from the time he sees him - as far away as he can see. He may not sit until he has reached his place or passed [beyond his field of vision] and is hidden.Should a nasi [desire to] waive the honor due him, he may forgo it.When the nasi enters, all the people should stand. They may not sit until he tells them to. When the av beit din enters, two rows are opened for him, and the people stand on either side until he enters and sits in his place. The other people remain seated in their places.

A student who is constantly sitting before his teacher is permitted to rise in his honor only [twice daily,] in the morning and in the evening, so that the honor paid to him does not exceed the honor paid to God.

Even though a person who disgraces a Torah sage will not receive a portion in the world to come, if witnesses come [and testify that] he disgraced him, even if only verbally, he is obligated to be placed under a ban of ostracism. This ban is publicly announced by the court. Also, wherever he is located, he is fined a litra of gold, which is given to the sage.Even one who disgraces a sage after his death is placed under a ban of ostracism by the court. They should release the ban when he repents. In contrast, if the sage is alive, they do not release the ban until he appeases the sage for whose [honor] he was ostracized.[To protect] his honor, a sage may issue a ban of ostracism against a common person who acted outrageously against him. He does not need witnesses, nor must [the offender] have been warned. The ban is not lifted until he appeases the sage. If the sage dies, three people may come and lift [the ban]. If the sage desires to forgive him and not place him under ban, he is permitted to do so.

Even though a sage who is distinguished for his wisdom, the nasi, or the av beit din acts shamefully, they should never be publically placed under a ban of ostracism unless their deeds resemble those of Jeroboam ben Nevat and his colleagues. However, if one [of these individuals] performs other sins, he should be lashed privately, as [implied by Hoshea 4:5]: “You shall stumble during the day and the prophet will stumble with you at night” - i.e., even though he stumbles, cover him like night. He is told: “Preserve your honor and stay at home.”Similarly, whenever a Torah sage is obligated to be ostracized, it is forbidden for a court to act rashly and pronounce a ban hastily. Instead, they should shun the matter and try to avoid it. The pious among the Sages would be proud of the fact that they never participated in the ostracism of a Torah sage. Nevertheless, they would participate in sentencing him to be lashed. They would even participate in sentencing him to receive “stripes for rebellion.”

Just as a person is commanded to honor his father and hold him in awe, so, too, is he obligated to honor his teacher and hold him in awe.[Indeed, the measure of honor and awe] due one's teacher exceeds that due one's father. His father brings him into the life of this world, while his teacher, who teaches him wisdom, brings him into the life of the world to come.[Accordingly,] if he saw a lost object belonging to his father and one belonging to his teacher, the lost object belonging to his teacher takes precedence. If his father and his teacher are both carrying loads, he should relieve his teacher's load, and then his father's. If his father and his teacher are held as captives, he should redeem his teacher, and afterwards, redeem his father. However, if his father is [also] a Torah sage, he should redeem his father first.[Similarly,] if his father is a Torah sage - even if he is not equivalent to his teacher - he should return his lost article, and then that belonging to his teacher.There is no greater honor than that due a teacher, and no greater awe than that due a teacher. Our Sages declared: "Your fear of your teacher should be equivalent to your fear of Heaven."Therefore, they said: Whoever disputes the authority of his teacher is considered as if he revolts against the Divine Presence, as implied [by Numbers 26:9]: "...who led a revolt against God."Whoever engages in controversy with his teacher is considered as if he engaged in controversy with the Divine Presence, as implied [by Numbers 20:13]: "...where the Jews contested with God and where He was sanctified."Whoever complains against his teacher is considered as if he complains against the Divine Presence, as implied [by Exodus 16:8]: "Your complaints are not against us, but against God."Whoever thinks disparagingly of his teacher is considered as if he thought disparagingly of the Divine Presence, as implied [by Numbers 21:5]: "And the people spoke out against God and Moses."

What is meant by disputing the authority of one's teacher? A person who establishes a house of study [where] he sits, explains, and teaches without his teacher's permission in his teacher's lifetime. [This applies] even when one's teacher is in another country.It is forbidden to ever render a halachic judgment in one's teacher's presence. Whoever renders a halachic judgment in his teacher's presence is worthy of death.

It is forbidden for a student to refer to his teacher by name, even outside his presence. He should not mention his name in his presence, even when referring to others with the same name as his teacher - as he does with the name of his father. Rather, he should refer to them with different names, even after their death.The above applies when the name is unusual, and all will thus know to whom it refers.[A student] should not greet his teacher or respond to the latter's greeting, as is customary when two friends exchange greetings. Rather, he should bow before him and say with awe and reverence: "Peace be upon you, my master." If his teacher greeted him, he should respond: "Peace be upon you, my teacher and master."

Similarly, he should not remove his tefillin in the presence of his teacher, nor should he recline in his presence. Rather, he should sit before him as one sits before a king.A person should not pray either in front of his teacher, behind his teacher, or at his teacher's side. Needless to say, one should not walk by his side. Rather, he should distance himself behind his teacher without standing directly behind him and then pray.One should not enter a bathhouse together with his teacher or sit in his teacher's place. One should not side against his teacher's opinion in his presence or contradict his statements. One should not sit in his presence until he tells him to sit. One should not stand before him until he tells him to stand or until he receives permission to stand.When one departs from his teacher, one should not turn his back to him. Rather, one should walk backwards while facing him.

A person is obligated to stand before his teacher from the time he sees him - as far away as he can see - until [he passes beyond his field of vision] and is hidden: his figure no longer visible. Then, [the student] may sit.A person is obligated to visit his teacher during the festivals.

[A student who] saw his teacher transgress the words of the Torah should tell him: you have taught us such and such.Whenever he mentions a teaching in his presence, he should tell him: "You have taught us the following, master." He should not mention a concept which he did not hear from his teacher unless he mentions the name of the person who authored it.When his teacher dies, he should rend all his garments until he reveals his heart. He should never mend them.When does the above apply? To one's outstanding teacher from whom one has gained the majority of his wisdom.However, a person who has not gained the majority of his wisdom under a teacher's instruction is considered to be both a student and colleague. He is not obligated to honor him in all the above matters. Nevertheless, he should stand before him, rend his garments at his [death], as he does for all the deceased for whom he is obligated to mourn. Even if he learned only one thing from him, whether it be a small or great matter, he should stand before him and rend his garments at his [death].

An outstanding teacher may, if he desires, forgo his honor with regard to any or all of the above matters to any or all his students.Even though he forgoes [these honors], the student is obligated to respect him at the time he forgoes [respect].

Just as students are obligated to honor their teacher, a teacher is obligated to honor his students and encourage them. Our Sages declared: "The honor of your students should be as dear to you as your own."A teacher should take care of his students and love them, because they are like sons who bring him pleasure in this world and in the world to come.

Students increase their teacher's wisdom and broaden his horizons. Our Sages declared: "I learned much wisdom from my teachers and even more from my colleagues. However, from my students [I learned] most of all."Just as a small branch is used to light a large bough, so a small student sharpens his teacher's [thinking processes], until, through his questions, he brings forth brilliant wisdom.

Just as a person is obligated to teach his son, so, too, is he obligated to teach his grandson, as [Deuteronomy 4:9] commands: "And you shall teach them to your sons and your grandsons."[Furthermore, this charge is not confined] to one's children and grandchildren alone. Rather, it is a mitzvah for each and every wise man to teach all students, even though they are not his children, as [Deuteronomy 6:7] states: "And you shall teach them to your sons..." The oral tradition explains: "Your sons," these are your students, for students are also called sons, as [II Kings 2:3] states: "And the sons of the prophets went forth."If so, why do the commandments [explicitly mention] one's son and grandson? To grant precedence to one's son over one's grandson, and one's grandson over the son of a colleague.
