Mga Sanggunian sa Mishnah para sa Isaias 1:18: Mishnah Negaim, Mishnah Yoma, Mishnah Shabbat & Mishnah Ketubot

If the two hairs were black at the root and white at the tip he is clean. If they were white at the root and black at the tip he is unclean. How much whiteness must there be? Rabbi Meir says: any amount. Rabbi Shimon says: enough to be cut with a pair of scissors. If it was single at the root but split at the tip, and it looks like two hairs, he is clean. If a bright spot had [two] white hairs or black hair he is unclean, for we are not concerned that the place of the black hair lessened the space of the bright spot, since the former is of no consequence.

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).

How do we know that if one [a woman] discharges semen on the third day she is unclean? Because it is said, “Be ready for the third day” (Exodus 19:15). How do we know that one who has been circumcised may be bathed on the third day [after circumcision] which falls on Shabbat? Because it is said, “And it came to pass on the third day, when they were in pain” (Genesis 34:25). How do we know that a crimson-colored strap is tied to the head of the goat that is sent [to Azazel]? Because it is said, “If your sins be as scarlet, they shall be as white as snow” (Isaiah 1:18).
