Slaughter on the North Side Binds the Flock but Not the Bird

(Leviticus 1:11) "And he shall slaughter it": it must be on the north side, but not the bird on the north side. Is this not a matter of logic? If a member of the flock, for which no particular priest is fixed, has the north fixed for it, then the bird, for which a priest is fixed, surely should have the north fixed for it. Therefore Scripture teaches, "and he shall slaughter it": it on the north, and not the bird on the north. Rabbi Eliezer ben Jacob says: "It" on the north, and not the Passover offering on the north. Is this not a matter of logic? If a burnt offering, for which no fixed time of slaughter was set, has a fixed place of slaughter set for it, then the Passover offering, for which a fixed time of slaughter was set, surely should have a fixed place of slaughter set for it. Therefore Scripture teaches, "it": it on the north, and not the Passover offering on the north. Rabbi Hiyya says: "It" on the north, and not the one who slaughters on the north. For we have learned that the one who receives the blood must stand on the north and receive on the north, and if he stood on the south and received on the north, it is invalid. One might think that if he stood on the south and slaughtered on the north it would be invalid; therefore Scripture teaches, "it": it on the north, and the one who slaughters need not stand on the north.
