Vayikra: Chapter 49
The greater Sanhedrin and the smaller Sanhedrin

We learn about the greater Sanhedrin of Moses and the smaller Sanhedrin of Aaron, both of which had seventy members. Moses was the best man of the King, Tiferet, while Aaron was the best man of the Queen, Malchut. This section tells about the seventy tongues, the seventy aspects of the Torah, the seventy interpretations of the holy tongue in the Torah, the numerical value of secret (sod), the chariot of seventy seats, and the seven Sfirot of Zeir Anpin each comprising ten. Moses and Aaron, the heads of the Sanhedrin, complete the number of the Sanhedrin to 72.
