Leviticus 13:2-3

Leeser(i) 2 If a man shall have in the skin of his flesh a swelling, a rising, or a bright spot, and it might become in the skin of his flesh the plague of leprosy: then shall he be brought unto Aaron the priest, or unto one of his sons the priests. 3 And if the priest shall see the plague in the skin of the flesh, and the hair in the plague be turned white, and the appearance of the plague be deeper than the skin of his flesh: it is a plague of leprosy; and so soon as the priest shall see him, he shall pronounce him unclean.
