Lev 14:2

14:2 cleansing. These ceremonies conducted by the priest did not cure skin disease. A diseased person came to the priest after he had been healed (Luke 5:14). The task of the priest was to make the person who had been excluded from the camp, from his people, and from God, ceremonially clean. Through these ceremonial cleansings, which took place in two stages a week apart, the diseased individual was restored to fellowship with God and with His people.
