Musar su Esodo 33:15

He continued by emphasizing ואראה את הארץ הטובה, "So that I may see the good land." I have already mentioned that there are many different levels of sanctity. Even though Moses thought that the lands of Sichon and Og were already part of the Holy Land, he was well aware that the West bank was of a higher level of sanctity than the East bank of the Jordan. Terrestrial ארץ ישראל is situated "opposite" ארץ ישראל של מעלה, Celestial Eretz Yisrael. The most holy part of terrestrial ארץ ישראל may be presumed to be "opposite" the holiest part of Celestial ארץ ישראל. Moses longed for the holiest part of ארץ ישראל למטה in order to be closest to the holiest part of ארץ ישראל למעלה. This is why he spoke of "the good Mountain, Lebanon," meaning the Temple Mount and site of the Holy of Holies on that Mount. He wished to be able to fulfill the commandments calling for one's presence in the Holy Land and, more specifically, in the Temple. When Moses continued (3,26) ויתעבר ה' בי למענכם, this means that G–d denied Moses' request precisely because granting it would result in the whole people being spiritually raised to a level even with Moses who had despised the angel. Israel was simply not worthy of such a level on its own merits. Only under Joshua, who enjoyed the assistance of the angel (Joshua 5,14) who introduced himself with the words "now I have come," could the conquest of the remainder of the land proceed. Moses had rejected that very angel in Exodus 33,15 as an inadequate level of Divine guidance. Moses therefore had to tell the people that his departure was due to their not meriting direct Divine guidance such they had enjoyed during his leadership. The scholars who specialize in רשומות, see in the respective first letters of the words גם בי התאנף ה' בגללכם an allusion to גרשוני מסתפח בנחלת ה' "G–d has expelled me from participating in His heritage."
