The Torah, “Numbers” 11:16 – 11:17: And the LORD said unto Moses: ‘Gather unto Me seventy men of the elders of Israel, whom thou knowest to be the elders of the people, and officers over them; and bring them unto the tent of meeting, that they may stand there with thee.
And I will come down and speak with thee there; and I will take of the spirit which is upon thee, and will put it upon them; and they shall bear the burden of the people with thee, that thou bear it not thyself alone.’
The Creator reassures Moses that the rage will not be poured unto him alone and that he will not carry the burden of the people by himself but that it will be shared by all the elders who will come in direct contact with the people, while Moses will teach the seventy elders and govern all the tribes by them.
The point is that when egoism begins grow inside us there is a need for a whole structure of connection with the Creator and all our modification and our improvement comes down to establishing it. In a family, for example, everything is managed by the head of the family; in an apartment building everything is managed by the condominium association; in a village there is a small managing board; in the city there is the municipality, and in a state thousands of people are involved in it, which means that the bigger our egoism grows the greater the need for the mutual connection between all the people and the upper force, the Creator.
If very large egoism is revealed among the people, the people begin to complain by turning to Moses: “We don’t want to advance; we would rather go back to the animal level. Take us back to Pharaoh and take the Creator.” It is one of the two: either Bina or Malchut, either money or the Upper Light.
This is the reason that there is suddenly the need for coordination because there has to be a conductor that connects Moses and the people. In this case the seventy sages, which is a whole system of mutual cooperation, are between them.
And I will come down and speak with thee there; and I will take of the spirit which is upon thee and will put it upon them… this means that the elders will ascend spiritually and thus will be able to be totally connected to each other.
They are able to take the upper Light and divide it to seventy parts (which means seven Sefirot: Hesed, Gevura, Tifferet, Netzach, Hod, Yesod, Malchut; in each if which there are ten Sefirot, which is a total of seventy), and to lead them to the people and show the people that they should unite and connect.
Seventy sages actually set the example for connection and unity: they are all different and opposite from one another as seventy spiritual roots. Eventually, like roots in the ground, they absorb all the people that stem from them in a chain reaction downwards. This is the reason that the seventy sages/seventy spiritual roots can set an example and strengthen the unity of the nation.
In the past, the Sanhedrin composed of seventy sages governed the state and thanks to the unity between them they could reach a consensus.
Everything that exists in the spiritual roots is reflected in the corporeal world. Therefore, there is this connection both in our souls and in our spiritual covenant.
There is the concept of a nation in each of us: first there is all of humanity, then the nation of Israel, and then its division to the Levites, the priests, the seventy sages, and Moses. We all have to be equal in this schema and to put it together between us in the corporeal world so that we will understand that it exists inside us.
