From the point of view of Bina, which Moses symbolizes, he connected with Malchut (the people of Israel) and transmitted all of his power to it so that the people could begin to rise from a state of Malchut in the Land of Israel (which had already been a different power of Malchut) to Bina.
This was the blessing through which he transferred power to the land and to the people, and the people had to implement them. The implementation includes clarification of the nature and the sequence of the corrective actions, as well as preparation of the people for movement and advancement in different forces (tribes), to individual people, tens, hundreds, and so forth.
This made it clear how they could continue to gather into greater unity in their constantly growing egoism and desire called the “Land of Israel” that was revealed by them and aim straight toward the Creator.
They began to fight in order to direct their desires toward bestowal and love, above the egoism that was depicted by the seven peoples, which were manifested in the seven structures: Hesed, Gevurah, Tifferet, Netzach, Hod, Yesod, and Malchut.
This was serious work, but Moses no longer had any connection with it because he was only the characteristic of Bina, and he only transmitted love and bestowal to the people of Israel. Working between the characteristic of bestowal and the zealous, powerful egoistic desire the “Land of Israel” will be the next level, Joshua ben Nun. This force would lead the people forward toward the Land of Israel.
