Our present mishnah is different from all those which have preceded it in this present chapter in two major ways. This is the first time that more than one 'saying' has been attributed to a sage; and this is the only saying in this chapter which is not in Hebrew (but in Aramaic). Perhaps I might be permitted to add from the personal point of view that it is fiendishly difficult to translate.

In view of everything that we have said concerning Hillel in the previous mishnah it is perhaps understandable that the contribution of this sage was considered so impressive that his ethics could not be compressed into one saying, so a second has been added. (There are some modern scholars who are of the opinion that the saying quoted in the next mishnah has been misattributed and that it too comes from Hillel.) The fact that the saying has been handed down to us in Aramaic is indicative of its homely authenticity. We do not have here a carefully honed saying handed down for the general edification of posterity. Our present mishnah takes us right into the Bet Midrash to hear Hillel instructing his students in their everyday language.

We mentioned above that Mishnah 13 is different from the others in this chapter that have come before in two major ways. Perhaps we can add a third difference, though this difference is admittedly much less essential. Most of the preceding 'sayings' have consisted of three clauses; our present mishnah consists of four clauses. Let us try to understand them seriatim.

A name made great is a name destroyed. Possibly here Hillel is addressing a problem he sees in some of his students. They study assiduously, but not in order to become more knowledgeable in Torah but in order to achieve fame and renown. Hillel here is probably echoing the teaching of his own teacher, Shemayah, a teaching which we have already considered in mishnah 10: Love work and hate [being in a position of] authority. But here Hillel is adding a further consideration why the sincerely religiously motivated person will wish to eschew publicity as far as possible. The more a person is known publicly the more his or her name becomes the subject of talk and - inevitably - gossip. We, immersed as we are in modern western culture, can certainly understand this. Not a day passes when we do not hear of some piece or other of detrimental gossip concerning this or that politician, this or that film star, this or that tycoon and so on. Our media thrive on this kind of pernicious trash. Hillel warns his students that 'a name made great is a name destroyed'. Perhaps it is only because of his own innate sense of personal humility, because of his own cultivated mild temper, that his name has reached us unbesmirched down the ages.
To be continued.
