render this immersion invalid or not? — He replied: ‘Whatever the Rabbis ordained, they endowed with the authority of a law of the Torah’. Said Abaye to R. Joseph: Is a partial entrance of the Sanctuary considered an entrance or not? — He answered: The thumb and toe will prove that, for there but a partial entrance is involved, and it was taught: A leper immerses himself and stands in the Nicanor Gate! — The question was asked: What about making for himself a long knife for slaughtering? This question is asked in accord with the view of both Ben Zoma and the Rabbis who oppose R. Judah. This question is asked on the view of Ben Zoma: Perhaps Ben Zoma does not consider the immersion obligatory except in the case of one who actually enters, but not for one who stands outside; or perhaps even for the latter, because he might gradually enter. The question is also asked according to the view of the Rabbis who oppose R. Judah: Perhaps the Rabbis hold their view only there because he does not perform a service, but where he officiates at a service they would agree, or do they make no difference? — The question remains unanswered. FIVE IMMERSIONS AND TEN SANCTIFICATIONS: Our Rabbis taught: The high priest underwent five immersions and ten sanctifications on that day, all of them on holy ground, in the Parwah Cell, with the exception of the first, which took place on profane ground, on top of the Water Gate, lying at the side of his [private] cell. Abaye said: We infer therefrom that the Etam well was [at least] twenty-three cubits above the ground of the Temple Court. For we have learnt: All the doorways there were twenty cubits in height, ten cubits in breadth, with the exception of that of the Hall and it was taught: And he shall bathe all his flesh in water, I.e., in the waters of a mikweh, in water which covers his whole body. What ‘is its quantity? One cubit square, three cubits high, and the Sages have calculated that the required quantity for [the contents of] a mikweh is forty se'ah. 13ᵃᵇᶜᵈᵉᶠᵍʰⁱʲᵏˡᵐ
