(Exodus 22:12) "If it were torn (by a wild beast), let him bring ed." This ("ed") is its hide. These are the words of R. Yoshiyah. Even though there is no proof for this (interpretation), there is support for it in (Amos 3:12) "Just as a shepherd can rescue from the mouth of a lion (just) two legs or the cartilage of an ear, etc." R. Yochanan b. Yoshiyah says: "If it were torn, let him bring ed." — Let him bring witnesses ("edim") that it was torn, and he will be exempt from paying.
