Bar Kappara on the Manna as Bread of the 248 Limbs

Bar Kappara said: What is the meaning of "fine and flaky" (mechuspas)? It is bread that was absorbed into the 248 limbs, corresponding to the numerical value of the letters of mechuspas: Mem is forty, Chet is eight, Samech is sixty, Peh is eighty, Samech is sixty — behold, two hundred and forty-eight, corresponding to the 248 limbs that are in a human being. As it is said, "Each one ate the bread of the mighty" (Psalms 78:25). Do not read "bread of the mighty" (abirim), but rather "bread of the limbs" (eivarim). The ministering angels would grind the manna, and it would come down to Israel, and they would eat it; and not one of them needed to relieve himself, because it was absorbed into the limbs. Thus "bread of the mighty" is "bread of the limbs."
