Summary: The Lord directed Moses and Aaron on handling potential leprosy, requiring priestly examination and, if confirmed, declaring the person unclean. Afflicted individuals had to signify their condition by their appearance, vocalize their unclean status, and live in isolation, highlighting the seriousness with which leprosy was treated.
The Lord said to Moses and Aaron, “If someone has on his skin a scab or pustule or blotch which appears to be the sore of leprosy, he shall be brought to Aaron, the priest, or to one of the priests among his descendants. If the man is leprous and unclean, the priest shall declare him unclean by reason of the sore on his head.
“The one who bears the sore of leprosy shall keep his garments rent and his head bare, and shall muffle his beard; he shall cry out, ‘Unclean, unclean!’ As long as the sore is on him he shall declare himself unclean, since he is in fact unclean. He shall dwell apart, making his abode outside the camp.”
