Leviticus 13:27-37

²⁷And the priest shall see him on the seventh day: if now it have spread abroad in the skin, then shall the priest pronounce him unclean: it is the plague of leprosy.

²⁸And if the bright spot remain in its place, and it have not spread abroad in the skin, and it be pale: it is a swelling of the fire-wound; and the priest shall pronounce him clean; for it is a scar of the fire-wound.

²⁹And if there be a man or woman on whom there arise a plague, on the head or on the beard;

³⁰Then shall the priest see the plague; and, behold, if its appearance be deeper than the skin, and there be in it a yellow thin hair: then shall the priest pronounce him unclean, it is a dry scall, it is the leprosy of the head or of the beard.

³¹And if the priest see the plague of the scall, and, behold, its appearance be not deeper than the skin, and there be no black hair in it: then shall the priest shut up the plague of the scall seven days.

³²And the priest shall see the plague on the seventh day; and, behold, if the scall have not spread, and there be in it no yellow hair, and the appearance of the scall be not deeper than the skin:

³³Then shall he be shaved, but the scall he shall not shave; and the priest shall shut up the scall seven days more.

³⁴And the priest shall see the scall on the seventh day; and, behold, if the scall have not spread in the skin, and its appearance be not deeper than the skin: then shall the priest pronounce him clean, and he shall wash his clothes, and be clean.

³⁵But if the scall should spread abroad in the skin after his being pronounced clean:

³⁶Then shall the priest see him; and, behold, if the scall have spread in the skin, the priest shall not seek for the yellow hair; he is unclean.

³⁷But if the scall have remained stationary in its color, and black hair have grown up therein: the scall is then healed, he is clean; and the priest shall pronounce him clean.
