TSK · Leviticus 14:37

and in the place of the boil there is a white rising, or a bright spot, reddish-white, then it shall be shown to the priest;

if the plague is greenish or reddish in the garment, or in the skin, or in the warp, or in the woof, or in anything made of skin; it is the plague of leprosy, and shall be shown to the priest.
