First reading: Leviticus 13:1-2,44-46

The Lord said to Moses and Aaron, ‘If a swelling or scab or shiny spot appears on a man’s skin, a case of leprosy of the skin is to be suspected. The man must be taken to Aaron, the priest, or to one of the priests who are his sons.

‘The man is leprous: he is unclean. The priest must declare him unclean; he is suffering from leprosy of the head. A man infected with leprosy must wear his clothing torn and his hair disordered; he must shield his upper lip and cry, “Unclean, unclean.” As long as the disease lasts he must be unclean; and therefore he must live apart: he must live outside the camp.’
