Leviticus 14:2-5

2“This is the law concerning the person afflicted with a skin disease on the day of his cleansing. He is to be brought to the priest,

3who will go outside the camp and examine him. If the skin disease has disappeared from the afflicted person,

4the priest will order that two live clean birds, cedar wood, scarlet yarn, and hyssop be brought for the one who is to be cleansed.

5Then the priest will order that one of the birds be slaughtered over fresh water in a clay pot.
