Мидраш к Бамидбар 12:11

R. Chama b. Chanina said: "What is the meaning of the passage (Pr. 27, 17) Iron is sharpened by iron? It means just as iron sharpens another iron, so also when two scholars study together, one sharpens [the intellect of] the other." Rabba b. b. Chana said: "Why are the words of the Torah compared to fire? As it is written (Jer. 23, 29) Is not this my word like the fire? saith the Lord. They are to teach that just as fire cannot burn of itself [without having hold of an object], so the words of the Torah can also not remain with one who is alone." And this is also meant by R. Jose b. Chanina; for R. Jose b. Chanina said: "What is the meaning of the passage (Jer. 50, 36) The sword is against the lying soothsayers and they should become foolish. It means that the sword is against the learned who sit alone and study the Torah in privacy. Moreover, they become foolish; as it is said (No'alu) and they shall become foolish; nay, more, they will commit sins; for it is written here (V'noalu) and they shall become foolish, and it is written there (Num. 12, 11) Wherein we have acted foolishly (No'alnu), and wherein we have sinned; and if you wish I would conclude here from (Is. 19, 13) that The princess of Tzo'an are becoming fools (No'alu)."

R. Tanchum b. Chanilai said: "Why is the tribe of Reuben mentioned first among the cities of safety? Because he was the first to save Joseph from his brothers, as it is written (Gen. 37, 21) And when Reuben heard it, he delivered him out of their hand." R. Simlai lectured: "It is written (Deut. 4, 41) Then Moses separated three cities beyond the Jordan, toward the sunrise. The Holy One, praised be He! said to Moses: 'Thou hast caused the sun to shine toward the murderers (to save them from death)'." R. Simlai lectured: "What is the meaning of the verse (Ecc. 5, 9) He that loveth silver shall not be satisfied with silver; nor he that loveth abundance, will finally have income? He that loveth silver refers to Moses, our master, who, [although] having been aware that the three cities on the other side of the Jordan could not protect [the innocent murderer] until the other three cities were selected; nevertheless he selected them, saying: "A meritorious act which has come to my hand, I shall fulfil;' nor he that loveth abundance, i.e., who is fit to lecture before a crowd? He who possesses all the grain [of knowledge] like the Bible, Mishna, Halacha and Hagada." And this is what R. Elazar said: "What is the meaning of the passage (Ps. 106, 2) Who can express the mighty acts of the Lord? or make all His praise to be heard? This means, who is fit to express the mighty acts of the Lord? He who can make all His praise to be heard." The Rabbis, and according to others, Rabba b. Mari explained this passage thus: "He who loves the abundance [of scholars], possesses the fruit of knowledge"; whereupon the Rabbis fixed their eyes upon Raba b. Rabba who possessed such a quality. R. Ashi said: "He who likes to learn among a crowd of scholars possesses the fruit of their knowledge." And this is what R. Jose b. Chanina said: "What is the meaning of the passage (Jer. 50, 36) The sword is upon the boasters (badim) and they shall become fools? This means the sword may cut the necks of the scholars who study separately [without interchange of ideas] and not only this, but they become also foolish; for it is written here, V'no-alu, (and they become foolish) and there is another passage (Num. 12, 11) For that we have done foolishly, and not only this but they also commit a crime, as it is written (Ib.) And wherein we have sinned. Rabina said: "He who loves to study among a crowd [of students], will possess the grain of knowledge." And this is what Rabbi said: "I learned much from my teachers, more, however, from my colleagues, but from my disciples, I learned the most."

(Exodus 17:9) "And Moses said to Joshua, etc.": whence it is seen that he equated Joshua with himself. All men are hereby apprised of proper deportment. Moses did not say to Joshua "Choose for me men," but "Choose for us men." And whence is it derived that the honor due one's friend is to be as beloved by him as the fear of his teacher? From (Numbers 12:11) "And Aaron said to Moses: 'I pray you, my lord.'" Now was Aaron not Moses' brother, and older than he? How, then, is "I pray you, my lord" to be understood? He equated him with his teacher. And whence is it derived that the fear of one's teacher is to be equated with that of Heaven? From (Numbers 11:28) "And Joshua the son of Nun, the attendant of Moses from his youth, answered: "My lord, Moses, destroy them" — Just as the L rd can destroy them, so, can you. And thus do you find with Gechazi. When Elisha said to him (II Kings 4:29) "Gird your loins and take my staff in your hand," he began to support himself on his staff and to go. They (i.e., strangers) asked him: Where are you going Gechazi? He answered: To revive the dead. They: Now can you revive the dead? Is it not written (I Samuel 2:6) "The L rd puts to death and brings to life"? He: My master, too, puts to death and brings to life.
