LET’S HANG ON TO WHAT WE GOT…

At Avot 3:10 Rabbi Dostai ben Yannai teaches in the name of Rabbi Meir a lesson that most of us would regard as easy to understand but extremely hard to apply:

כָּל הַשּׁוֹכֵֽחַ דָּבָר אֶחָד מִמִּשְׁנָתוֹ, מַעֲלֶה עָלָיו הַכָּתוּב כְּאִלּוּ מִתְחַיֵּב בְּנַפְשׁוֹ, שֶׁנֶּאֱמַר: רַק הִשָּֽׁמֶר לְךָ וּשְׁמֹר נַפְשְׁךָ מְאֹד פֶּן תִּשְׁכַּח אֶת הַדְּבָרִים אֲשֶׁר רָאוּ עֵינֶֽיךָ. יָכוֹל אֲפִילוּ תָּקְפָה עָלָיו מִשְׁנָתוֹ, תַּלְמוּד לוֹמַר: וּפֶן יָסֽוּרוּ מִלְּבָבְךָ כֹּל יְמֵי חַיֶּֽיךָ, הָא אֵינוֹ מִתְחַיֵּב בְּנַפְשׁוֹ עַד שֶׁיֵּשֵׁב וִיסִירֵם מִלִּבּוֹ

Anyone who forgets even a single word of this learning, the Torah considers it as if he had forfeited his life. As is stated, "Just be careful, and very much guard your soul, lest you forget the things that your eyes have seen" (Devarim 4:9). One might think that this applies also to one who [has forgotten because] his studies proved too difficult for him; but the verse continues "and lest they be removed from your heart, throughout the days of your life." From this we see that one does not forfeit his life unless he deliberately removes them from his heart.

For any Jew learning Torah today, the task is in many respects incomparably harder than it was for the Sages of the Mishnah: Rabbi Dostai and his contemporaries had ‘only’ to master the canonical books of the Tanach plus the Oral Law that Rabbi Yehudah eventually organized into the Six Orders of the Mishnah and the accompanying teachings that became known as baraitot, toseftot and midrash. They never had to face the task of conquering what was to become a possibly exponential growth of literature ranging from the commentaries and codifications of the Rishonim through to the generally far more voluminous output of the Acharonim.  On the other hand, without the convenience of the printed text and the luxury of online data retrieval, anything they failed to commit to memory or were able to explain cogently to others was liable to be lost forever.

The Chasid Yavetz places this mishnah within the context of the arrangement of teachings in the third chapter of Avot. There it follows a series of six mishnayot that deal with different aspects of Torah: sharing it with others, not turning away from it but adhering to it, the importance of studying it with others and the need to resist the temptation to be distracted while learning it.  Once we have mastered these matters, we are all set for a promising role as a talmid chacham—someone who is wise in the ways of the Torah—but there is still one thing left to address.

Explains the Chasid Yavetz, there is a parallel between the pursuit of Torah and the pursuit of profit in the business world. Most of us are probably familiar with the types of businessmen that inhabit our commercial world. Discounting those poor souls who really don’t have a clue, there are three other personalities in the business world: those who make money and don’t know how to hang on to it, those who know exactly how to hang onto it but never seem to be able to make it, and those happy folk who possess the knack of making money and the wherewithal to safeguard it. So too in the world of Torah, we see those who know how to learn but can’t retain it, those who would retain it well if they could but remember it, and those who are not only good at learning but keep their knowledge and their understanding secure. The Chasid Yavetz bases his categorization on the proof verse from Devarim and the two verses that precede it, though he could equally have treated it as an echo of the -authored “four types of Torah student” mishnah at Avot 5:15.

The obvious line of protection against forgetting one’s Torah is the principle of “let’s hang on to what we got”, this being the practice of regularly revising what we have learned. Curiously, this important learning technique is not explicitly mentioned anywhere in the tractate of Avot—though there is something of a tradition that incorporates it. We learn Avot from Pesach to Shavuot, the period of sefirat ha’omer (this being 49 days), but only 48 elements of acquiring Torah are listed in the baraita of Avot 6:6. Each day of the sefirat ha’omer corresponds to one of those 48 elements, leaving the 49th and final day for chazarah (“revision”). I heard this from Rabbi Eli Brunner zt’l, who heard it from Rabbi Elya Lopian. If anyone has an authentic source drawn from our earlier Sages, can they please let me know.

I don’t suppose that many, and perhaps any, serious and sincere contemporary Torah scholars would ever go about deliberately forgetting any part of their Torah learning except possibly where they had mis-learned it in the first place and had to put it right out of their minds before seeking to re-learn it properly. But there may be another form of forgetting that is more than merely accidental but certainly not malicious. An argument in Jewish law may be complex, built on the interrelationship of several different propositions—and sometimes when we apply layers of halachic propositions one after another we reach a result that is so absurd or self-evidently wrong that we deliberately reject it and start again. It may be that, in this process of rejection, a valid Torah proposition is set aside too and is subsequently forgotten. I like to think that our God, being all-knowing and merciful, would not condemn this form of forgetfulness.
