the red cow must have a certain weight (as will be explained). Rabha answered him: Concerning the weight, the opinion of the Tanaim are different; consequently, no prescribed quantity is needed. When R. Dimi came from Palestine, he said in the name of R. Johanan: I have heard of three tongues of wool: one for the red cow, one for the scapegoat, and one for lepers. I have heard, one must be of the weight of 10 Zuz, one must have the weight of 2 Selas, and one of 1 Shekel, but I cannot explain which. When Rabbin came from Palestine, he explained this in the words of R. Jonathan: That for the red cow must weigh 10 Zuz, for the scapegoat 2 Selas, and for lepers 1 Shekel. (For the red cow, which must have a certain weight, it is 10 Zuz; that of the goat, which must be divided, 2 Selas; and the leper's, which need be neither, it is a Shekel.)
R. Itz'hak said: I have heard about the two slaughterings, of the red cow and of the high-priest's bull, one, if done by a layman, is valid, and the other is, in such a case, invalid; but I cannot explain which it is. It was taught: Concerning the slaughtering of the red cow and the high-priest's bull, Rabh and Samuel differed. One said, if the red cow was slaughtered by a layman, it is valid, and the bull, invalid; and the other says the reverse.
It may be ascertained that Rabh is the one who says that the red cow slaughtered by a layman is invalid, because (when Rabh heard) R. Zerah said that the red cow slaughtered by a layman is invalid, Rabh said: The reason is, that in connection with the red cow is mentioned Elazar (a priest) and "statute."
It was taught: Concerning the slaughtering of the red cow by a layman, R. Ammi said: It is valid; R. Itz'hak of Naph'ha said: It is invalid; Ulla said: It is valid; and others say; It is invalid. R. Joshua b. Abba objected to the statement that it is valid, and wanted to support Rabh from the following: Boraitha: It is certain to us that the sprinkling of the water of the red cow is invalid, if a woman has done it instead of a man, or when it was not sprinkled in the daytime. But whence do we deduce further that the slaughtering of it, and receiving of the blood, and sprinkling of the blood, and burning it, and the putting in of the cedar-wood, hyssop, scarlet string, is invalid in such cases? Therefore it is written, "The law."
Shall we assume that to them shall be added the gathering of the ashes, and the drawing of the water, and the sanctification? Therefore it is written: "This" is the statute [Num. xix. 2].
