“When a man has on the skin of his body a swelling, a scab, or a bright spot, and it shall become on the skin of his body like a leprous infection, then he shall be brought to Aharon the priest or to one of his sons the priests.
“And the priest shall look at him on the seventh day. If it spreads further over the skin, then the priest shall pronounce him unclean, it is a leprous infection.
“And the priest shall look at him again on the seventh day and see, if the infection has darkened, and the infection has not spread on the skin, then the priest shall pronounce him clean. It is a scab, and he shall wash his garments and be clean.
