Leviticus 13:1-14

1Then the Lord spoke to Moses and to Aaron, saying,

2“When a man has a swelling on the skin of his body, a scab, or a bright spot, and it becomes the infection of leprosy on the skin of his body, then he shall be brought to Aaron the priest, or to one of his sons the priests.

3The priest shall look at the diseased spot on the skin of his body, and if the hair in the infection has turned white and the infection appears deeper than the skin of his body, it is an infection of leprosy; when the priest has looked at him, he shall pronounce him [ceremonially] unclean.

4If the bright spot is white on the skin of his body and does not appear to be deeper than the skin, and the hair on it has not turned white, the priest shall isolate the person who has the infection for seven days.

5The priest shall examine it on the seventh day, and if in his estimation the infection has not changed and has not spread on the skin, then the priest shall isolate him for seven more days.

6The priest shall examine him again on the seventh day, and if the infection has a more normal color and the spot has not spread on the skin, the priest shall pronounce him clean; it is only a scab; and he shall wash his clothes and be clean.

7“But if the scab spreads farther on the skin after he has shown himself to the priest for his [ceremonial] cleansing, he shall show himself to the priest again.

8The priest shall look, and if the scab has spread on the skin, then he shall pronounce him unclean; it is leprosy.

9“When a leprous infection is on a person, he shall be brought to the priest.

10The priest shall examine him, and if there is a white swelling on the skin and it has turned the hair white and there is new raw flesh in the swelling,

11it is a chronic leprosy on the skin of his body, and the priest shall pronounce him unclean; he shall not isolate him because he is [clearly] unclean.

12But if the [suspected] leprosy breaks out farther on the skin, and it covers all of the skin of the one who has the outbreak—from his head to his foot—wherever the priest looks,

13the priest shall examine him. If the [suspected] leprosy has covered his entire body, he shall pronounce him clean of the disease; it has all turned white, and he is clean.

14But whenever raw flesh appears on him, he shall be unclean.
