Leviticus 14:1-7 New Revised Standard Version (NRSV)
Purification of Lepers and Leprous Houses
14 The Lord spoke to Moses, saying: 2 This shall be the ritual for the leprous[a] person at the time of his cleansing:
He shall be brought to the priest; 3 the priest shall go out of the camp, and the priest shall make an examination. If the disease is healed in the leprous[b] person, 4 the priest shall command that two living clean birds and cedarwood and crimson yarn and hyssop be brought for the one who is to be cleansed. 5 The priest shall command that one of the birds be slaughtered over fresh water in an earthen vessel. 6 He shall take the living bird with the cedarwood and the crimson yarn and the hyssop, and dip them and the living bird in the blood of the bird that was slaughtered over the fresh water. 7 He shall sprinkle it seven times upon the one who is to be cleansed of the leprous[c] disease; then he shall pronounce him clean, and he shall let the living bird go into the open field.
