Leviticus 13:2-19

²When 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 to Aaron the priest, or to one of his sons the priests:

³And the priest shall look on the plague in the skin of the flesh: and when the hair in the plague is turned white, and the plague in sight is deeper than the skin of his flesh, it is a plague of leprosy: and the priest shall look on him, and pronounce him unclean.

⁴If the bright spot is white in the skin of his flesh, and in sight, not deeper than the skin, and the hair of it not turned white; then the priest shall shut up him that hath the plague seven days:

⁵And the priest shall look on him the seventh day: and behold, if the plague in his sight is at a stay, and the plague spreadeth not in the skin; then the priest shall shut him up seven days more:

⁶And the priest shall look on him again the seventh day: and behold, if the plague is somewhat dark, and the plague spreadeth not in the skin, the priest shall pronounce him clean: it is but a scab: and he shall wash his clothes, and be clean.

⁷But if the scab shall spread much in the skin, after he hath been seen by the priest for his cleansing, he shall be seen by the priest again:

⁸And if the priest shall see, that behold, the scab spreadeth in the skin, then the priest shall pronounce him unclean: it is a leprosy.

⁹When the plague of leprosy is in a man, then he shall be brought to the priest:

¹⁰And the priest shall see him : and behold, if the rising is white in the skin, and it hath turned the hair white, and there is raw flesh in the rising;

¹¹It is an old leprosy in the skin of his flesh, and the priest shall pronounce him unclean, and shall not shut him up; for he is unclean.

¹²And if a leprosy shall break out in the skin, and the leprosy shall cover all the skin of him that hath the plague from his head even to his foot, wherever the priest looketh;

¹³Then the priest shall consider: and behold, if the leprosy hath covered all his flesh, he shall pronounce him clean that hath the plague: it is all turned white: he is clean.

¹⁴But when raw flesh appeareth in him, he shall be unclean.

¹⁵And the priest shall see the raw flesh, and pronounce him to be unclean: for the raw flesh is unclean: it is a leprosy.

¹⁶Or if the raw flesh shall turn again, and be changed into white, he shall come to the priest;

¹⁷And the priest shall see him: and behold, if the plague is turned into white: then the priest shall pronounce him clean that hath the plague: he is clean.

¹⁸The flesh also, in which, even in the skin of it, was a boil, and is healed,

¹⁹And in the place of the boil there shall be a white rising, or a bright spot, white, and somewhat reddish, and it be showed to the priest;
