Musar do Przysłów 8:21

I once read an explanation of this: When a man commits adultery a malignant spirit is created in the form of the woman with whom he strayed. Then, when his time comes to leave this world, she wraps herself around him and drags him down to Gehinnom. It seems to me that this is what the Sages were alluding to when they said (Sanhedrin 100a), “In the future the Holy One Blessed is He will bestow upon every righteous person three hundred and ten worlds. As it is written, ‘To cause those who love Me to inherit substance (yeish, the numerical value of which is 310)’ (Mishlei 8:21).” I have heard this passage explained as follows: As we have already mentioned, when a man does a single mitzvah a single angel is created. The Sages tell us (Chullin 91b) that each angel is two thousand parsaos across (1 parsah = 2.80 miles.), as it is written, “And its body was like [the Sea of] Tarsus” (Daniel 10:6). According to tradition this sea was two thousand parsaos wide. Now altogether there are 613 Torah precepts and seven rabbinical enactments, totaling 620, the numerical value of the word keser — “crown.” Therefore, when the Jewish people keep the entire Torah, including the rabbinical injunctions, they acquire 620 angels.

This is a further reason why we have a statement that every righteous person will inherit 310 worlds in the future (Proverbs 8,21 — להנחיל לאוהבי יש as interpreted in the introduction to Tractate Avot). The worlds referred to are the worlds of Atzilut, Briyah, Yetzirah and Assiyah. There is no need for an allusion to the עולם האצילות seeing it has infinite dimensions which are impossible to symbolize by numbers. In that world there is something much closer to absolute unity than in any of the "worlds" which form part of the process of development. Since, however, even that world of emanations divides into ten parts, it is alluded to by the number 10 rather than 100.

All the descendants of Jacob will have a share in the world to come. The words (28,11) וישכב במקום ההוא which introduces Jacob's dream, contain most of these allusions. The word וישכב must be divided into two words, i.e. ויש, and כ"ב. The word ויש alludes to the world of the future, as we know from Proverbs 8,21: להנחיל אוהב יש, "in order to make those who love Me inherit something of substance." Our tradition interprets this statement to mean that every צדיק in the future will inherit 310=שי worlds (Uktzin 3,12). This corresponds to the nation ישראל, which is alluded to in the letters כ"ב, (metaphor for the alphabet which makes up the Torah).
