Rebbi says: I can read "Eat of it only roasted in fire." Why "raw and vashel mevushal"? For I might then think that it is only when he is commanded to eat it roasted (i.e., at night) that he is forbidden to eat it raw or cooked. Whence would I derive (the same for) the daytime? It is, therefore, written "uvashel mevushal" (connoting "whenever it is cooked").
