purify

Torah: parah aduma, which is the ritual of purifying a person who has come into contact with a dead body. During the ritual of parah aduma, the Kohen slaughters a red cow that has never born a yoke and then burns the carcass along with cedar, hyssop and a crimson substance until it has been reduced to ashes. The ashes are then mixed with water and sprinkled on the person who has come in contact with death, thus rendering him pure.
