פירוש על קידושין 105:9

Rava cites a baraita that supports Rav. The baraita refers to priests dividing up the weekly showbread. The modest ones did not even want to eat it. Perhaps they felt it was too holy. In their place, the gluttonous ones take all of the shares. This seems to imply that they can exchange their portions—the modest ones do not take and in their place others do.

The Talmud rejects this meaning of “shared.” The gluttonous did not share their portions, they snatched, i.e. stole, them from one another. Those greedy priests!
