But if the scab spreads further on his skin after he has presented himself to the priest for his cleansing, he is to present himself again to the priest.
The priest will re-examine him on the seventh day. If it has spread further on the skin, the priest must pronounce him unclean; it is in fact a case of serious skin disease.
‘When a person has a swelling, scab, or spot on the skin of his body, and it may be a serious disease on the skin of his body, he is to be brought to the priest Aaron or to one of his sons, the priests.
The priest will examine him again on the seventh day. If the sore has faded and has not spread on the skin, the priest is to pronounce him clean; it is a scab. The person is to wash his clothes and will become clean.
