Leviticus 14:2-5

2“This is the law of the diseased person on the day of his purification, when he is brought to the priest.

3The priest is to go outside the camp and examine the infection. If the infection of the diseased person has been healed,

4then the priest will command that two live clean birds, a piece of cedar wood, a scrap of crimson fabric, and some twigs of hyssop be taken up for the one being cleansed.

5The priest will then command that one bird be slaughtered into a clay vessel over fresh water.
