The tunic [worn by the High Priest] atoned for bloodshed, the breeches atoned for lewdness, the turban made atonement for arrogance, the belt atoned for [impure] meditations of the heart, the breastplate atoned for neglect of civil laws, the apron atoned for idolatry, the cloak atoned for slander, and the crown, worn on the forehead, atoned for brazenness.
Talmud, Zevachim 88b
