Day of Atonement (Yom Kippur)

When the scapegoat was selected on Yom Kippur to symbolically carry the people’s sins to the desert, a crimson cord was tied around its horns. While the practical purpose of this cord was to distinguish the scapegoat from the goat which was to be slaughtered, it also symbolized the sin which the scapegoat was carrying away. Isaiah 1:18 promises that if the Jewish people repents, “if [their] sins are like crimson, they shall become white as snow.” According to tradition, in some years the scapegoat’s cord would miraculously turn white to indicate that the people’s sins were forgiven and purification achieved in that year.

Hmm.
