Leviticus 13:2-19

²When a man shall have in the skin of his flesh a rising or a scab, or bright spot, and it become in the skin of his flesh a sore as of leprosy, then he shall be brought unto Aaron the priest, or unto one of his sons the priests.

³And when the priest looketh on the sore in the skin of the flesh, and the hair in the sore is turned white, and the sore looketh deeper than the skin of his flesh, it is the sore of leprosy; and the priest shall look on him and pronounce him unclean.

⁴But if the bright spot be white in the skin of his flesh, and look not deeper than the skin, and the hair thereof be not turned white, the priest shall shut up him that hath the sore seven days.

⁵And the priest shall look on him the seventh day; and behold, in his sight, the sore remaineth as it was, the sore hath not spread in the skin, then the priest shall shut him up seven days a second time.

⁶And the priest shall look on him again the seventh day, and behold, the sore is become pale and the sore hath not spread in the skin, then the priest shall pronounce him clean; it is a scab; and he shall wash his garments and be clean.

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

⁸and the priest shall look on him, and behold, the scab hath spread in the skin; then the priest shall pronounce him unclean: it is leprosy.

⁹When a sore as of leprosy is in a man, he shall be brought unto the priest;

¹⁰and the priest shall look on him, and behold, there is a white rising in the skin, and it hath turned the hair white, and a trace of raw flesh is in the rising:

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

¹²But if the leprosy break out much in the skin, and the leprosy cover all the skin of him that hath the sore, from his head even to his foot, wherever the eyes of the priest look,

¹³and the priest looketh, and behold, the leprosy covereth all his flesh, he shall pronounce him clean that hath the sore; it is all turned white; he is clean.

¹⁴And on the day when raw flesh appeareth in him, he shall be unclean.

¹⁵And the priest shall look on the raw flesh, and shall pronounce him unclean: the raw flesh is unclean, it is leprosy.

¹⁶But if the raw flesh change again, and be turned white, he shall come unto the priest;

¹⁷and the priest shall look on him, and behold, the sore is turned white; then the priest shall pronounce him clean that hath the sore: he is clean.

¹⁸And the flesh — when in the skin thereof cometh a boil, and it is healed,

¹⁹and there is in the place of the boil a white rising, or a white-reddish bright spot, it shall be shewn to the priest;
