What is Torah Learning?

(9) Two are better off than one, in that they have greater benefit from their earnings. (10) For should they fall, one can raise the other; but unfortunate for one who is alone and falls with no companion to raise them

Rabbi Ḥama, son of Rabbi Ḥanina, said: What is the meaning of that which is written: “Iron sharpens iron, so a man sharpens the countenance of his friend” (Proverbs 27:17)? This verse comes to tell you that just as with these iron implements, one sharpens the other when they are rubbed against each other, so too, when Torah scholars study together, they sharpen one another in halakha.

Rabba bar bar Ḥana said: Why are matters of Torah compared to fire, as it is stated: “Is not My word like fire, says the Lord” (Jeremiah 23:29)? To tell you: Just as fire does not ignite in a lone stick of wood but in a pile of kindling, so too, matters of Torah are not retained and understood properly by a lone scholar who studies by himself, but by a group of Sages.

And this is what Rabbi Yosei bar Ḥanina said: What is the meaning of that which is written: “A sword is upon the boasters, and they shall become fools ” (Jeremiah 50:36)? This verse can be interpreted homiletically: There is a sword upon the enemies of Torah scholars, a euphemism for Torah scholars themselves, who sit alone and study Torah. And not only that, but those who study by themselves grow foolish from their solitary Torah study, as it is stated: “And they shall become fools.”

...Rav Naḥman bar Yitzḥak said: Why are Torah matters likened to a tree, as it is stated: “It is a tree of life to them who lay hold upon it” (Proverbs 3:18)? This verse comes to tell you that just as a small piece of wood can ignite a large piece, so too, minor Torah scholars can sharpen great Torah scholars and enable them to advance in their studies. And this is what Rabbi Ḥanina said: I have learned much from my teachers and even more from my friends, but from my students I have learned more than from all of them.

Rabbi Yochanan used to go and sit by the gates of the Mikvah. He used to say, "let the women of Israel look at me as they leave the Mikvah, so that they may go and make sons as wise and beautiful as myself

What is meant [by childlessness] ? Is it to be supposed to refer to a man who had children but they died ? Lo, R. Johanan himself said, "This is the bone of my tenth son!" (interpreted as his tenth son who died)

The Gemara recounts a related incident: Reish Lakish sold himself to gladiators. He took a bag and a round stone inside of it with him. He said: There is a tradition that on the final day of a captive’s life, before his captors kill him, they do for him anything that he requests of them, so that he would forgive them for the spilling of his blood. On the final day before they were set to kill him they said to him: What is amenable to you? He said to them: I want to tie you up and have you sit, and I will strike each one of you one and a half times. He tied them up and had each one of them sit. When he struck each of them with one strike with the stone in the bag, the one whom he struck died, because Reish Lakish was of great strength. Reish Lakish gritted his teeth in anger, and said to the one whom he killed, in order to prevent the others from realizing what was happening: Are you laughing at me? You still have half of a strike remaining with me, as I struck you only once. He killed them all, and Reish Lakish escaped his captors. He left and came back home, and after some time had passed he was sitting, eating, and drinking, without concern for his livelihood. His daughter said to him: You don’t want something to lie upon? He said to her: My daughter, my belly is my pillow, and this is enough for me.

The Gemara relates: One day, Rabbi Yoḥanan was bathing in the Jordan River. Reish Lakish saw him and jumped into the Jordan, pursuing him. At that time, Reish Lakish was the leader of a band of marauders. Rabbi Yoḥanan said to Reish Lakish: Your strength is fit for Torah study. Reish Lakish said to him: Your beauty is fit for women. Rabbi Yoḥanan said to him: If you return to the pursuit of Torah, I will give you my sister in marriage, who is more beautiful than I am. Reish Lakish accepted upon himself to study Torah. Subsequently, Reish Lakish wanted to jump back out of the river to bring back his clothes, but he was unable to return.

Rabbi Yoḥanan taught Reish Lakish Bible, and taught him Mishna, and turned him into a great man. Eventually, Reish Lakish became one of the outstanding Torah scholars of his generation.

One day the Sages of the study hall were engaging in a dispute concerning the following text: With regard to the sword, the knife, the dagger [vehapigyon], the spear, a hand sickle, and a harvest sickle, from when are they susceptible to ritual impurity? The text answers: It is from the time of the completion of their manufacture, which is the halakha with regard to metal vessels in general. These Sages inquired: And when is the completion of their manufacture? Rabbi Yoḥanan says: It is from when one fires these items in the furnace. Reish Lakish said: It is from when one scours them in water, after they have been fired in the furnace.

Rabbi Yoḥanan said to Reish Lakish: A bandit knows about his banditry, i.e., you are an expert in weaponry because you were a bandit in your youth. Reish Lakish said to Rabbi Yoḥanan: What benefit did you provide me by bringing me close to Torah? There, among the bandits, they called me: Leader of the bandits, and here, too, they call me: Leader of the bandits. Rabbi Yoḥanan said to him: I provided benefit to you, as I brought you close to God, under the wings of the Divine Presence. As a result of the quarrel, Rabbi Yoḥanan was offended, which in turn affected Reish Lakish, who fell ill.

Rabbi Yoḥanan’s sister, who was Reish Lakish’s wife, came crying to Rabbi Yoḥanan, begging that he pray for Reish Lakish’s recovery. She said to him: Do this for the sake of my children, so that they should have a father. Rabbi Yoḥanan said to her the verse: “Leave your fatherless children, I will rear them” (Jeremiah 49:11), i.e., I will take care of them. She said to him: Do so for the sake of my widowhood. He said to her the rest of the verse: “And let your widows trust in Me.”

Ultimately, Rabbi Shimon ben Lakish, Reish Lakish, died. Rabbi Yoḥanan was sorely pained over losing him. The Rabbis said: Who will go to calm Rabbi Yoḥanan’s mind and comfort him over his loss? They said: Let Rabbi Elazar ben Pedat go, as his statements are sharp, i.e., he is clever and will be able to serve as a substitute for Reish Lakish. Rabbi Elazar ben Pedat went and sat before Rabbi Yoḥanan.

With regard to every matter that Rabbi Yoḥanan would say, Rabbi Elazar ben Pedat would say to him: There is a ruling which is taught in a baraita that supports your opinion. Rabbi Yoḥanan said to him: Are you comparable to the son of Lakish? In my discussions with the son of Lakish, when I would state a matter, he would raise twenty-four difficulties against me in an attempt to disprove my claim, and I would answer him with twenty-four answers, and the halakha/Jewish law by itself would become broadened and clarified. And yet you say to me: There is a ruling which is taught in a text that supports your opinion. Do I not know that what I say is good? Being rebutted by Reish Lakish served a purpose; your bringing proof to my statements does not.

Rabbi Yoḥanan went around, rending his clothing, weeping and saying: Where are you, son of Lakish? Where are you, son of Lakish? Rabbi Yoḥanan screamed until his mind was taken from him, i.e., he went insane. The Rabbis prayed and requested for God to have mercy on him and take his soul, and Rabbi Yoḥanan died.

(5) The clean parts of a wagon are the following: the yoke that is only plated [with metal], side-pieces made for ornamentation, tubes that give out a noise, the lead at the side of the necks of the cattle, the rim of the wheel, the plates and mountings, and all other nails, all of these are clean. Metal shoes of cattle are susceptible to impurity but those made of cork are clean. When does a sword become susceptible to impurity? When it has been polished. And a knife? When it has been sharpened.

Just as there is fraud regarding commerce, so, too, is there fraud regarding words, and the fraud regarding words is worse than that with money, for one can return money but cannot return words.
