Musar do Ozeasza 2:9

Once Jacob died, Moses became the second "husband" of the relevant שכינה [presumably the "upper" one, בינה, seeing that Moses had attained 49 of the 50 levels of בינה Ed.]. However, this union could last only while Moses lived on this earth, since upon the death of a wife's second husband she "returns" to her former husband, having only been on "loan" during the interval. Since Jacob was by then in the Holy Land, Moses, automatically had to remain outside the Holy Land. The reason that Jacob was buried body and bones in ארץ ישראל is that he represented the גוף, body, of the ארץ של ישראל סבא, as we have mentioned before. Joseph, being the extension of his father, was the extension of the גוף, limbs or bones. These "bones" symbolize the spiritual forces or permutations of G–d's Ineffable Name that radiate in all directions from the emanation בינה, enabling a physical universe to take shape. A צדיק, as such is also called צבאות, part of G–d's armies or executive arm. It was therefore appropriate that Joseph's bones rather than his entire body were interred in ארץ ישראל. None of this reflects negatively on Moses. On the contrary, whereas Moses was able to establish a union with the "upper" level of the שכינה during his life on earth, Jacob established his union with that level of the שכינה only after he had departed. We find an allusion to Moses' intimacy with that part of the שכינה in Numbers 7,89, where the way the Torah describes Moses' being at home in the אהל מועד, the visible manifestation of the בינה on earth, is most striking. Moses did not need to be invited in; he acted as if he were the owner of that domain. The author finds in the number of the 600,000 Jews that left Egypt allusions to the radiations of the various combinations of G–d's Name in all the six directions of the compass, proof that Moses led the people by means of the power inherent in the emanation בינה. If Moses was already on such a level while his soul was still enshrined in his body, it is clear that once Moses died, his soul would ascend to an even higher region than the level represented by בינה. That level, which we have described elsewhere as יובל, is beyond any level associated with any of the three levels to which the term ארץ can be applied. Moses' being "buried" in what we commonly call חוץ לארץ is a compliment to him thus rather than a reminder of some inadequacy on his part. In fact, once Moses' life on earth had come to an end, he joined the souls of "his" 600,000 people who also had not been buried in the Holy Land. If we find that Moses separated from his terrestrial wife Tzipporah –something used by his sister Miriam as an accusation against him in Numbers 12,1 – the reason was simply that Moses had already "used" [in the sense that one has relations with one's wife. Ed.] the spiritual light from extra-terrestrial regions as we know from Exodus 34,29 where Moses is described as emitting supernatural light from his face. Having a "wife" in those regions, it is easy to understand that Moses could no longer share life with a wife on earth. Jacob, on the other hand, had married four wives and had shared a fully terrestrial life with them, one of the reasons that his bed, מטה, was called שלימה, "complete" by our sages. This means that only upon his death did his רוח ונשמה, soul and spirit, merit entry to the seventh level i.e. בינה.
