Então Aharon entrará na Tenda do Encontro, tirará as vestes de linho que vestiu ao entrar no Santo Lugar e as deixará ali.
Mishnah Yoma
They said to the high priest: the goat has reached the wilderness. And how did they know that the goat had reached the wilderness?They used to set up scouts and they would wave scarves, and they would know that the goat had reached the wilderness. Rabbi Judah said: but did they not have a great sign? From Jerusalem to Bet Hidudo was three mils. They could walk a mil, return the mil, then wait the time it takes to walk a mil, and thus know that the goat had reached the wilderness. Rabbi Ishmael said: but did they not have another sign! A thread of crimson wool was tied to the door of the Temple, and when the goat reached the wilderness the thread turned white, as it is written, “Though your sins be as scarlet they shall be as white as snow” (Isaiah 1:18).
