Rabbi Yochanan

Rabbi Yochanan, also called bar Nafcha, was an Amora, one of the sages whose discussions make up the Gemara. He learned from Rabbi Yannai and Rabbi Hoshaya. He taught Reish Lakish, to whom he offered his sister in marriage, and Reish Lakish would ask him twenty-four questions on what he said. He also taught Rabbi Elazar. The Gemara passes down in his name the rule that the law follows an anonymous Mishnah. Later sages in the Gemara quote a rule that the law follows him against Rav, with three exceptions, and against Shmuel.

Who he was

Who was Rabbi Yochanan?

The Gemara in Bava Metzia calls him "bar Nafcha", which means "son of the smith". Rabbi Zeira tells that Rabbi Yosei son of Rabbi Chanina appeared to him at night and told him who is placed next to whom. Rabbi Yochanan is next to Rabbi Yannai. Rabbi Zeira asked why Rabbi Yochanan is not next to Rabbi Chiya. The answer was: in a place of sparks and burning fire, who can bring bar Nafcha in there?

מַאן מְעַיֵּיל בַּר נַפָּחָא לְתַמָּן
"Who can bring bar Nafcha in there?"
Speaking: Rabbi Zeira, repeating what Rabbi Yosei son of Rabbi Chanina told him when he appeared to him at night
Bava Metzia 85bRead it on Sefaria

The Gemara asks why Rabbi Yochanan minded so much. It answers with a teaching of Rav: King David asked Hashem that his teachings be said in his name in this world. It then adds a teaching that Rabbi Yochanan himself passed on in the name of Rabbi Shimon bar Yochai: when people say a Torah scholar's teaching in his name in this world, his lips move in the grave.

כׇּל תַּלְמִיד חָכָם שֶׁאוֹמְרִים דְּבַר שְׁמוּעָה מִפִּיו בָּעוֹלָם הַזֶּה, שִׂפְתוֹתָיו דּוֹבְבוֹת בַּקֶּבֶר
"Any Torah scholar in whose name a teaching is said in this world, his lips move in the grave."
Speaking: The Gemara, quoting Rabbi Yochanan in the name of Rabbi Shimon bar Yochai
Yevamot 96b-97aRead it on Sefaria

He said that the heart of the early generations was as wide as the doorway of the Ulam, the entrance hall of the Temple, and the heart of the later ones as wide as the doorway of the Heikhal, the Temple's main hall. "And we", he said, are like the eye of a fine needle.

לִבָּן שֶׁל רִאשׁוֹנִים כְּפִתְחוֹ שֶׁל אוּלָם, וְשֶׁל אַחֲרוֹנִים כְּפִתְחוֹ שֶׁל הֵיכָל, וְאָנוּ: כִּמְלֹא נֶקֶב מַחַט סִידְקִית
"The heart of the early ones was like the doorway of the Ulam, that of the later ones like the doorway of the Heikhal, and we are like the eye of a fine needle."

Teachers and students

Who he learned from and who learned from him

Each link below has a passage behind it.

Rabbi Yannai was his teacher. In the Gemara in Yevamot, Rabbi Yannai reports a ruling, and Rabbi Yochanan calls him "Rabbi", which means "my teacher", and points out that the ruling can already be found in a Mishnah. (The Mishnah is the collection of laws that the Gemara explains.) Rabbi Yannai answers: if I had not lifted the piece of pottery for you, would you have found the pearl under it?

אֲמַר לֵיהּ רַבִּי יוֹחָנָן: רַבִּי, לֹא מִשְׁנָתֵנוּ הִיא זוֹ
"Rabbi Yochanan said to him: My teacher, is this not our Mishnah?"
Speaking: The Gemara narrates; Rabbi Yochanan is speaking to Rabbi Yannai
Yevamot 92bRead it on Sefaria

He learned Torah from Rabbi Hoshaya (this passage spells the name Rabbi Oshaya). He remembered how crowded it was: the students sat four to a cubit, a space about as long as a forearm. On the same page he says that Rabbi Oshaya in his generation was like Rabbi Meir in his: his friends could not get to the bottom of his thinking.

כְּשֶׁהָיִינוּ לוֹמְדִין תּוֹרָה אֵצֶל רַבִּי אוֹשַׁעְיָא, הָיִינוּ יוֹשְׁבִין אַרְבָּעָה אַרְבָּעָה בְּאַמָּה
"When we learned Torah with Rabbi Oshaya, we sat four to a cubit."
Speaking: Rabbi Yochanan
Eruvin 53aRead it on Sefaria

He never knew his parents. The Gemara in Kiddushin says that his father died while his mother was pregnant with him, and his mother died when he was born. In a discussion of how hard it is to honor parents properly, he says: happy is the one who never saw them.

מֵת אָבִיו, יְלָדַתּוּ – מֵתָה אִמּוֹ
"his father died; when she gave birth to him, his mother died."
Speaking: The Gemara narrates
Kiddushin 31bRead it on Sefaria

He lost children. The Gemara in Berakhot quotes him as saying "this is the bone of the tenth son", and it brings this as a case of a person who had children and they died.

וְהָא אָמַר רַבִּי יוֹחָנָן, דֵּין גַּרְמָא דַּעֲשִׂירָאָה בִּיר
"But Rabbi Yochanan said: this is the bone of the tenth son."

The meeting at the Jordan

One day Rabbi Yochanan was bathing in the Jordan River, and Reish Lakish saw him and jumped into the Jordan after him. Rabbi Yochanan told him: your strength should be for Torah. He said that if Reish Lakish would turn back, he would give him his sister in marriage, and Reish Lakish accepted.

אֲמַר לֵיהּ חֵילָךְ לְאוֹרָיְיתָא
"He said to him: your strength for Torah."
Speaking: The Gemara narrates; Rabbi Yochanan is speaking to Reish Lakish
Bava Metzia 84aRead it on Sefaria

Reish Lakish began as his student. After the meeting at the Jordan, the Gemara says that Rabbi Yochanan taught him Scripture, taught him Mishnah, and made him a great man.

אַקְרְיֵיהּ וְאַתְנְיֵיהּ וְשַׁוְּיֵיהּ גַּבְרָא רַבָּא
"He taught him Scripture, taught him Mishnah, and made him a great man."
Speaking: The Gemara narrates

After that argument Rabbi Yochanan was hurt, and Reish Lakish became ill. Rabbi Yochanan's sister came crying. She said to him: do it for the sake of my children. He answered with a verse from Yirmiyahu: leave your orphans, I will keep them alive. She said: do it for the sake of my widowhood. He answered with the rest of the verse: let your widows trust in Me. The Gemara records no other answer from him.

חֲלַשׁ דַּעְתֵּיהּ דְּרַבִּי יוֹחָנָן, חֲלַשׁ רֵישׁ לָקִישׁ. אֲתַאי אֲחָתֵיהּ קָא בָכְיָא
"Rabbi Yochanan was hurt; Reish Lakish became ill; his sister came crying."
Speaking: The Gemara narrates
Bava Metzia 84aRead it on Sefaria

Rabbi Elazar was his student. Rabbi Yaakov bar Idi calmed Rabbi Yochanan with a comparison. Yehoshua did not say "Moshe told me this" every time he taught, and everyone knew it was Moshe's Torah. In the same way, he said, your student Rabbi Elazar teaches without a name and everyone knows it is yours. (This passage says only "Rabbi Elazar". The passage about Reish Lakish's death gives the full name, Rabbi Elazar ben Pedat.)

אַף רַבִּי אֶלְעָזָר תַּלְמִידְךָ יוֹשֵׁב וְדוֹרֵשׁ סְתָם, וְהַכֹּל יוֹדְעִין כִּי שֶׁלְּךָ הִיא
"So too your student Rabbi Elazar sits and teaches without a name, and everyone knows that it is yours."

Stories

Stories about Rabbi Yochanan

Each story is told from one book, named under the quote.

When is a sword finished?

One day the study hall argued about a sword, a knife, a dagger, a spear and sickles. They can become impure only once they are finished, so when is that? Rabbi Yochanan said: when they are hardened in the furnace. Reish Lakish said: when they are polished in water. Rabbi Yochanan said to him, "A robber knows his robbery." The Gemara does not explain these words here (see the next item). Reish Lakish answered: and what good did you do me? There they called me master, and here they call me master. Rabbi Yochanan said: I did you good, because I brought you under the wings of the Shekhinah, the presence of God.

לִסְטָאָה בְּלִסְטְיוּתֵיהּ יָדַע
"A robber knows his robbery."
Speaking: Rabbi Yochanan, speaking to Reish Lakish

The robber line: Rashi's explanation

Rashi, the main commentary on the Gemara, explains what Rabbi Yochanan meant: because you were a robber, you are an expert in the tools of that trade. On Reish Lakish's answer, "there they called me master", Rashi explains: I was the master and head of the robbers.

לפי שהיית לסטים אתה בקי באותן כלי אומנות ליסטיות
"Because you were a robber, you are an expert in the tools of that trade."
Speaking: Rashi

Twenty-four questions

Reish Lakish died and Rabbi Yochanan grieved deeply. The Rabbis asked who would go to settle his mind, and sent Rabbi Elazar ben Pedat, whose teachings were sharp. Whatever Rabbi Yochanan said, Rabbi Elazar told him that there is a baraita that supports him. (A baraita is a teaching from the time of the Mishnah that was not put into the Mishnah.) Rabbi Yochanan said: are you like the son of Lakish? When I said something, the son of Lakish would ask me twenty-four questions and I would give him twenty-four answers, and so the teaching opened up. And you say there is a baraita that supports me. Do I not know that what I say is right?

הֲוָה מַקְשֵׁי לִי עֶשְׂרִין וְאַרְבַּע קוּשְׁיָיתָא, וּמְפָרְקִינָא לֵיהּ עֶשְׂרִין וְאַרְבְּעָה פֵּרוּקֵי, וּמִמֵּילָא רָוְוחָא שְׁמַעְתָּא
"He would ask me twenty-four questions and I would give him twenty-four answers, and so the teaching opened up."

Where are you, son of Lakish?

Rabbi Yochanan went about tearing his clothes and crying, "Where are you, son of Lakish?" He cried out until his mind left him. The Rabbis prayed for mercy for him, and he died.

הֵיכָא אַתְּ בַּר לָקִישָׁא, הֵיכָא אַתְּ בַּר לָקִישָׁא
"Where are you, son of Lakish? Where are you, son of Lakish?"

He and Ilfa: staying to learn

Ilfa and Rabbi Yochanan learned Torah together and were very poor, so they set out to go into business. They sat down to eat under a shaky wall, and Rabbi Yochanan heard two angels speaking. One said: let us throw this wall on them and kill them, because they leave "the life of the World to Come" and busy themselves with "the life of the hour". The other said to leave them, because the hour stands for one of them. Ilfa heard nothing, so Rabbi Yochanan understood that it meant him. He went back and Ilfa did not. By the time Ilfa came, Rabbi Yochanan "reigned". People said to Ilfa: if you had sat and learned, would you not be the one who reigns?

רַבִּי יוֹחָנָן הֲדַר, אִילְפָא לָא הֲדַר. עַד דַּאֲתָא אִילְפָא, מָלֵיךְ רַבִּי יוֹחָנָן
"Rabbi Yochanan went back; Ilfa did not go back. By the time Ilfa came, Rabbi Yochanan reigned."

What "reigned" means: Rashi's explanation

The Gemara says only that Rabbi Yochanan "reigned". Rashi explains: they appointed him head of the yeshiva over them.

Give me your hand

Rabbi Chiya bar Abba was ill and Rabbi Yochanan went in to visit him. He asked: is your suffering dear to you? Rabbi Chiya bar Abba answered: not it and not its reward. Rabbi Yochanan said, "Give me your hand." He gave him his hand, and Rabbi Yochanan raised him up.

אֲמַר לֵיהּ: הַב לִי יְדָךְ. יְהַב לֵיהּ יְדֵיהּ, וְאוֹקְמֵיהּ
"He said to him: give me your hand. He gave him his hand, and he raised him up."

A teaching said without his name

Rabbi Elazar taught a law in the study hall and did not say it in Rabbi Yochanan's name. Rabbi Yochanan heard and was upset. Rabbi Ammi and Rabbi Assi went in to him and told him a story about an argument between two earlier sages. He became more upset.

וְלָא אַמְרַהּ מִשְּׁמֵיהּ דְּרַבִּי יוֹחָנָן. שְׁמַע רַבִּי יוֹחָנָן אִיקְּפַד

How he rules

How Rabbi Yochanan thinks

Every item says who is making the claim: the Gemara itself, a classical commentator, or a modern writer.

The Gemara says

The law follows an anonymous Mishnah

The Gemara in Shabbat quotes a rule in his name: the law follows a "stam Mishnah", a Mishnah taught with no sage's name on it. On this page the Gemara uses the rule to test one of his own rulings. The ruling seems to go against such a Mishnah, so it asks: did Rabbi Yochanan really say that? But he said that the law follows an anonymous Mishnah. Rabbi Zeira answers by reading that Mishnah as a narrower case, "so as not to break the words of Rabbi Yochanan".

וְהָאָמַר רַבִּי יוֹחָנָן: הֲלָכָה כִּסְתָם מִשְׁנָה
"But Rabbi Yochanan said: the law follows an anonymous Mishnah."
Speaking: The Gemara, quoting Rabbi Yochanan; the answer at the end is Rabbi Zeira's

Two reports of his rule that do not match

In Ketubot, Rabbi Abba bar Yaakov reports that Rabbi Yochanan ruled like Rabban Shimon ben Gamliel in a certain case. The Gemara asks: did he really say this? Rabbah bar bar Chana reported in his name a general rule, that wherever Rabban Shimon ben Gamliel taught in our Mishnah the law follows him, except in three cases. The Gemara answers that these are two Amoraim who disagree about what Rabbi Yochanan held.

אָמוֹרָאֵי נִינְהוּ וְאַלִּיבָּא דְּרַבִּי יוֹחָנָן
"They are Amoraim, and they disagree about Rabbi Yochanan's view."
Speaking: The Gemara
Ketubot 77aRead it on Sefaria
The Gemara says

Two Tannaim "said the same thing"

The Tannaim are the sages of the Mishnah. In Menachot, Rabbi Reuven sends word in Rabbi Yochanan's name that the names in a certain teaching should be switched. The Gemara says that Rabbi Yochanan "follows his own reasoning", because he said that Rabbi Yosei HaGelili and one of Rabbi Yishmael's students "said the same thing". The Gemara identifies the student as Rabbi Yoshiya, and then brings his teaching.

וְאַזְדָּא רַבִּי יוֹחָנָן לְטַעְמֵיהּ, דְּאָמַר רַבִּי יוֹחָנָן: רַבִּי יוֹסֵי הַגְּלִילִי וְאֶחָד מִתַּלְמִידֵי רַבִּי יִשְׁמָעֵאל אָמְרוּ דָּבָר אֶחָד
"And Rabbi Yochanan follows his own reasoning, for Rabbi Yochanan said: Rabbi Yosei HaGelili and one of the students of Rabbi Yishmael said the same thing."

Menachot 57bRead it on Sefaria
The Gemara says

Half a measure is forbidden by the Torah

The Torah punishes eating forbidden food only from a set amount. What about less than that amount? Rabbi Yochanan says it is forbidden by the Torah, and Reish Lakish says it is not forbidden by the Torah itself. (The Gemara goes on to say that, for Reish Lakish, it is forbidden by the Rabbis.) The Gemara gives Rabbi Yochanan's reason: the small amount can join with more to make the full amount, so the person is eating something forbidden.

רַבִּי יוֹחָנָן אָמַר אָסוּר מִן הַתּוֹרָה: כֵּיוָן דַּחֲזִי לְאִיצְטְרוֹפֵי, אִיסּוּרָא קָא אָכֵיל
"Rabbi Yochanan said it is forbidden by the Torah: since it is fit to combine, he is eating something forbidden."

The Gemara says

A right to the fruit is like owning the land

A man sells his field only for its produce. Does the buyer read the declaration of thanks when he brings the first fruits to the Temple? Rabbi Yochanan says he brings them and reads it, because owning the right to the produce is like owning the land itself. Reish Lakish says he brings them and does not read it.

רַבִּי יוֹחָנָן אָמַר מֵבִיא וְקוֹרֵא – קִנְיַן פֵּירוֹת כְּקִנְיַן הַגּוּף דָּמֵי

But in three cases the law follows Rav

The same rule has a limit. In a similar case Rav Papa says that he might have made a mistake and answered with the rule "Rav and Rabbi Yochanan: the law follows Rabbi Yochanan". But Rava said that the law follows Rav in these three cases, whether that makes the law easier or stricter.

הָא אָמַר רָבָא: הִלְכְתָא כְּוָתֵיהּ דְּרַב בְּהָנֵי תְּלָת, בֵּין לְקוּלָּא בֵּין לְחוּמְרָא

The halacha

Whose view is the law?

These are general rules. The Gemara itself lists exceptions.

The Gemara says

Against Rav, the law follows him

Rav was an Amora of Bavel. In Beitzah a man asks Rav Ada bar Ahava a question about eggs, and Rav Ada bar Ahava answers him: what are you thinking, that when Rav and Rabbi Yochanan disagree the law follows Rabbi Yochanan? He speaks of it as a rule that was already known, and then explains that even Rabbi Yochanan would not permit what the man wanted.

רַב וְרַבִּי יוֹחָנָן: הֲלָכָה כְּרַבִּי יוֹחָנָן
"Rav and Rabbi Yochanan: the law follows Rabbi Yochanan."

Beitzah 4aRead it on Sefaria
The Gemara says

Against Shmuel, the law follows him

Shmuel was an Amora of Bavel. In Eruvin, Rava gives a ruling, and Ravina challenges him: are you relying on what Shmuel said? But when Shmuel and Rabbi Yochanan disagree, the law follows Rabbi Yochanan, and Rabbi Yochanan ruled the other way. Rava then changes his ruling.

וְהָא שְׁמוּאֵל וְרַבִּי יוֹחָנָן: הֲלָכָה כְּרַבִּי יוֹחָנָן
"But Shmuel and Rabbi Yochanan: the law follows Rabbi Yochanan."

The Gemara says

Three cases where the law follows Reish Lakish

Rava says that the law follows Reish Lakish "in these three" disputes with Rabbi Yochanan, and the Gemara lists them. The third one, on the next page of Yevamot, is a case where Rabbi Yochanan's reason is that a right to the produce is like owning the thing itself. The Gemara here lists only these three cases. It does not state a general rule for all their other disputes.

אָמַר רָבָא: הִלְכְתָא כְּווֹתֵיהּ דְּרֵישׁ לָקִישׁ בְּהָנֵי תְּלָת
