הלכה על קידושין 132:24

From the laws of the commandment is that which they, may their memory be blessed, said (Kiddushin 66b) that both one with a permanent blemish or [ one with] a transient blemish disqualifies the service and is lashed - if he served (transgressed) volitionally. And that which they, may their memory be blessed, said (Mishnah Middot 5:4) that the Great Court would sit in the chamber of hewn stone and their main constant activity was to check the priests in their pedigree and their blemishes. And any priest that was found to be disqualified in his pedigree wears black, wraps himself in black and goes out of the [Temple] yard. But one found complete and fit wears white, enters and serves with his brother priests. And one who was found fit in his pedigree but a blemish was found on him sits in the chamber of wood and removes the wormy wood for the arrangement [of wood]. And he divides the holy foods with his clan and eats, as it is stated (Leviticus 21:22), "The bread of His God from the holy of the holies and from the holy he may eat." And the rest of the laws of all of the blemishes are in Bekhorot, the seventh chapter.
