Leviticus 14:2-4

2“This shall be the law of the person with leprosy on the day of his cleansing. 1Now he shall be brought to the priest;

3and the priest shall go 2out to a place outside of the camp. Then the priest shall look, and if the 3leprous infection has been healed in the person with leprosy,

4then the priest shall give orders to take two live clean birds, 4cedar wood, a 5scarlet string, and hyssop for the one who is to be cleansed.
