Manna from Heaven and the power of ko'ach

There’s a long and puzzling Baraita at Avot 6:8 which opens like this:

רַבִּי שִׁמְעוֹן בֶּן יְהוּדָה מִשּׁוּם רַבִּי שִׁמְעוֹן בֶּן יוֹחָאִי אוֹמֵר: הַנּוֹי, וְהַכֹּֽחַ, וְהָעֹֽשֶׁר, וְהַכָּבוֹד, וְהַחָכְמָה, וְהַזִּקְנָה, וְהַשֵּׂיבָה, וְהַבָּנִים, נָאֶה לַצַּדִּיקִים וְנָאֶה לָעוֹלָם,

[Translation] Rabbi Shimon ben Yehudah used to say in the name of Rabbi Shimon bar Yochai: “Beauty, strength, wealth, honor, wisdom, sageness, old age and children—these befit the righteous and befit the world”.

Of the many questions this statement raises, one is this: what specifically does strength have to do with the righteous? Since the sixth chapter of Avot deals with Torah and how to acquire it, we can reasonably suppose that the reference to the righteous in our baraita is an allusion to those who are righteous on account of their commitment to Torah. Does Torah make them strong? No, it seems. We learn that the study of Torah matashet kocho shel adam (“weakens a man’s strength”: Rabbi Chanan, at Sanhedrin 26b).

A possible explanation is that Rabbi Chanan’s statement that Torah learning weakens a person’s strength relates solely to physical strength, but that the baraita does not. The Hebrew word ַכחַ (ko’ach, literally “strength”) also connotes “power” in the sense of “having an ability” to do something. But is there any support for this answer?

One of the things that children learn in the earliest stages of their Jewish education is that, when the Children of Israel spent 40 years in the desert, they ate manna every day. This manna, which fell miraculously from Heaven, had the wonderful quality of tasting like what each person wanted it to taste like, so they never got bored with it. Few Jewish adults look beyond this cute little story to see how it is utilised by the Sages. If they did, they would find that there’s more to midrash than delicious food falling out of the sky. Here’s Yalkut Shimoni, Yitro 286, discussing the revelation of God at Mount Sinai when he gave the Jewish people the Torah (with emphases added):

Rabbi Levi said: The Holy One blessed be He appeared to them like a portrait that is visible from all angles. A thousand people may gaze at it and it gazes back at all of them. It’s the same with the Holy One, blessed be He. When He spoke, every single Israelite said: “The Word spoke to me! It’s not written ‘I am the Lord your God but I am the Lord thy God” [note: Hebrew uses different words to indicate plural or singular forms of the second person. So too does old English, where “your” means “belonging to more than one” while “thy” means “belonging to only one other”].

Rabbi Yose said: The Word spoke to each and everyone according to their personal capacity. Don’t be surprised at the manna that came down to the Israelites, each person tasting the flavour he was able to appreciate—infants in accordance with their capacities, young men in accordance with theirs and the old in accordance with theirs. If that was the case for the manna, where everyone tasted the flavour he could appreciate, how much more so does this apply to the Word [of God].

David said: קוֹל-יְהוָה בַּכֹּחַ “The voice of the Lord is in strength”: Tehillim 29:4). It doesn’t say “in his strength but just “in strength”, meaning in accordance with the capabilities of each person.

Now the Baraita at Avot 6:8 can be seen in a fresh light. The righteous, in pursuing their path in accordance with the precepts of the Torah, need כֹֽחַ in the sense of the ability to discern the many different dimensions of the Torah’s content and to identify the approach that is most appropriate or efficacious in any given situation.

A final thought. When we wish one another yashir ko’ach (or yashir kochachah), is this simply a Hebrew version of “here’s power to your elbow!”—or does it convey a subtle midrashic connotation too?
