THE HIGH PRIEST SAYS THE NAME YHVH

The Talmud in Yoma 41b describes this event.

He [the high priest] bound a thread of crimson wool on the head of the he goat which was to be sent away, and [meantime] he placed it [at the gate] whence it was to be sent away; and the he goat that was to be slaughtered, at the place of the slaughtering, he came to his bullock a second time, pressed his two hands upon it and made confession. And thus he would say: O Lord, I have dealt wrongfully, I have transgressed, I have sinned before thee, I and my house, and the children of Aaron, thy holy people, O Lord, pray forgive the wrongdoings, the transgression, and the sins, which I have committed, transgressed, and sinned before thee, I and my house, and the children of Aaron, your holy people. As it is written in the Torah of Moses, your servant: for on this day atonement be made for you, to cleanse you; from all the sins shall you be clean before the Lord. And they responded: Blessed be the name of his glorious kingdom for ever and ever.
