Leviticus 14:3-5

Revised Standard Version Catholic Edition

³ and the priest shall go out of the camp, and the priest shall make an examination. Then, if the leprous disease is healed in the leper, ⁴ the priest shall command them to take for him who is to be cleansed two living clean birds and cedarwood and scarlet stuff and hyssop; ⁵ and the priest shall command them to kill one of the birds in an earthen vessel over running water.
