민수기 11:21의 Musar

The words: ויתעבר ה' בי למענכם in 3,26 also contain a mystical dimension. This also touches upon the subject of the great gift of Torah G–d has bestowed on the Jewish people. I have found the following comment among the writings of a great Kabbalistic scholar Rabbi Chayim, the leading disciple of the Arizal. [I will paraphrase his comments Ed.] "As a consequence of Moses' accepting the mixed multitude as converts, he became involved in the סוד העיבור, the calculations pertaining to leap months, leap years, etc., as well as their halachic implications of the time conceptions can take place. One of these calculations involves determining when a Jubilee year occurs (the fiftieth year after the conclusion of seven periods of seven years). G–d had not wanted to accept this mixed multitude as converts. Had they not been accepted, Israel would neither have experienced death nor exile, since the acceptance of the Tablets would have signified everlasting life, as our sages (Eruvin 54 on Exodus 32,16) have taught us when they said: אל תקרא חרות אלא חירות, "do not read 'engraved' i.e. Charut but 'Free' (from death) i.e. Cheyrut." Moses had not consulted G–d before accepting this mixed multitude, thinking that he was performing a good deed by bringing them closer to G–d (which had been Abraham's lifework). In addition he had developed a personal interest in the conduct of these people as he had hinted when he referred to them (Numbers 11,21) as העם אשר אנכי בקרבו, "the people amongst whom I find myself." He had also foretold that these people would convert when he told Pharaoh in Exodus 11,8 that כל העם אשר ברגליך ישתחוו לי, "all these people who now sit at your feet will bow down to me." This meant that Moses was anxious to convert these people. Alas, not only did Moses fail to truly convert them, but they also infected the Israelites proper with their lack of faith during the episode of the golden calf, so that G–d told Moses: לך רד כי שחת עמך, "Go and descend, for your people have become corrupt" (Exodus 32,7). These people and their offspring by now made up the majority of the Jews in the desert. This is why Moses was forced to insert an extra year after every 49 years. This extra year serves as a warning that Israel must not again err by accepting converts wholesale and be misled by them. [I suspect that the association between "freedom" which is emphasized in the יובל- year legislation of the Torah -although the Torah calls it דרור- (Leviticus 25,10), forms the background to the סוד העיבור which Rabbi Chayim calls "this involvement of Moses in each generation in the determination of the Jubilee year." He must mean that the need to proclaim freedom would not have arisen but for Moses' accepting the mixed multitude when he did Ed.]
