Leviticus 13:2

When a person has on the skin of his body a swelling or an eruption or a spot , and it turns into a case of leprous disease on the skin of his body , then he shall be brought to Aaron the priest or to one of his sons the priests ,

“When anyone has a swelling or a rash or a shiny spot on their skin that may be a defiling skin disease, they must be brought to Aaron the priest or to one of his sons who is a priest.

When a man shall have in the skin of his flesh a rising, a scab, or bright spot, and it be in the skin of his flesh like the plague of leprosy; then he shall be brought unto Aaron the priest, or unto one of his sons the priests :
