Chp. 14 verses 1 - 4: Introduction, Hashem tells Moshe about the laws of the purification of the leper on the day of his purification. He is brought to the edge of the camp and the priest goes out and checks to see if he had been healed from his leprosy. If found to be cured they take for him two pure birds, cedar wood, scarlet wool, and a bunch of hyssop.
