פרשת ויקהל

(1) Moses then convoked the whole Israelite community and said to them: These are the things that the LORD has commanded you to do: (2) On six days work may be done, but on the seventh day you shall have a sabbath of complete rest, holy to the LORD; whoever does any work on it shall be put to death. (3) You shall kindle no fire throughout your settlements on the sabbath day.

The Gemara relates that those same Sages who sat and discussed the issue of hides, sat again and they raised a dilemma: That which we learned in the mishna: The primary categories of labor, which are prohibited by Torah law on Shabbat, are forty-less-one; to what does this number correspond? That is to say, what is the source of this number?

Rabbi Ḥanina bar Ḥama said to them: They correspond to the labors in the Tabernacle. All types of labor that were performed in the Tabernacle are enumerated as primary categories of labor with respect to Shabbat. However, other labors, even if they are significant, are not enumerated among the primary categories of labor since they were not performed in the Tabernacle. Rabbi Yonatan, son of Rabbi Elazar, said to them that so said Rabbi Shimon, son of Rabbi Yosei ben Lakonya: They correspond to the instances of the words labor, his labor, and the labor of, that appear in the Torah a total of forty-less-one times.

The primary labors are forty less one:sowing, plowing, reaping, binding sheaves, threshing, winnowing, selecting, grinding, sifting, kneading, baking, shearing wool, bleaching, hackling, dyeing, spinning, weaving, the making of two loops, weaving two threads, dividing two threads, tying and untying, sewing two stitches, tearing in order to sew two stitches, capturing a deer, slaughtering, or flaying, or salting it, curing its hide, scraping it [of its hair], cutting it up, writing two letters, erasing in order to write two letters [over the erasure], building, tearing down, extinguishing, kindling, striking with a hammer, [and] carrying out from one domain to another, These are the forty primary labors less one.

The Sages taught in a Tosefta: One who sees multitudes of Israel recites: Blessed…Who knows all secrets. Why is this? He sees a whole nation whose minds are unlike each other and whose faces are unlike each other, and He Who knows all secrets, God, knows what is in each of their hearts. The Gemara relates: Ben Zoma once saw a multitude [okhlosa] of Israel while standing on a stair on the Temple Mount. He immediately recited: Blessed…Who knows all secrets and Blessed…Who created all these to serve me.

Explaining his custom, he would say: How much effort did Adam the first man exert before he found bread to eat: He plowed, sowed, reaped, sheaved, threshed, winnowed in the wind, separated the grain from the chaff, ground the grain into flour, sifted, kneaded, and baked and only thereafter he ate. And I, on the other hand, wake up and find all of these prepared for me. Human society employs a division of labor, and each individual benefits from the service of the entire world. Similarly, how much effort did Adam the first man exert before he found a garment to wear? He sheared, laundered, combed, spun and wove, and only thereafter he found a garment to wear. And I, on the other hand, wake up and find all of these prepared for me. Members of all nations, merchants and craftsmen, diligently come to the entrance of my home, and I wake up and find all of these before me.
