Five immersions and then 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.
