Musar su Ezechiele 34:13

We always proceed from the premise that all of Israel is considered נפש אחת, a single soul, life-force. Israel as a whole is called by the title אדם. As a reminder of this fact the family members of Jacob, 66 in number, who moved from the land of Canaan to Egypt in Genesis 46,26 are referred to as נפש, soul, or person, in the singular. Just as a body possesses 248 limbs, so the Jewish national body, known as אדם, comprises a great number of parts. The Zohar refers to these parts as שייפא דגופא, shavings or splinters of a body There are, of course, different levels of importance among the various parts of a regular body. The same is true when we describe the parts of the body which make up the Jewish nation. There is a head, a heart, an eye, a hand, etc. However, just as all the parts of the body combine to make a whole human being, so all the parts of the Jewish nation combine to make it one unit. The unit created by these many parts in turn combines to form the chariot, מרכבה, of the spiritual counterpart of terrestrial man in the Celestial Regions. This celestial אדם is perceived as sitting on the throne which is one of the 248 spiritual limbs that form the root of the 248 positive commandments, which, if performed by terrestrial man, are his true source of life (אשר יעשה אותם האדם וחי בהם Leviticus 18, 5).
