There were various purifying ceremonies. Bathing the flesh and the clothes in running water was used in all, and sufficed in the simplest cases. When the uncleanness was of a deeper character, a purifying water for sprinkling was provided: e.g., after contact with a corpse, water mingled with the ashes of a red cow (Num. 19: 9); for the leper, water in which the blood of a bird had been allowed to fall (Lev. 14: 6). In some cases sin and trespass offerings were also made; e.g., a man with an issue (Lev. 15: 13-14); a woman after childbirth (Lev. 12: 6, 8); and above all, the leper (Lev. 14: 2-32).
