'Leprous' in the Bible
'When a man hath in the skin of his flesh a rising, or scab, or bright spot, and it hath become in the skin of his flesh a leprous plague, then he hath been brought in unto Aaron the priest, or unto one of his sons the priests;
The 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.
He is a leprous man, he is unclean: the priest shall pronounce him utterly unclean; his plague is in his head.
if the mark is greenish or reddish in the garment or in the leather, or in the warp or in the woof, or in any article of leather, it is a leprous mark and shall be shown to the priest.
He shall then look at the mark on the seventh day; if the mark has spread in the garment, whether in the warp or in the woof, or in the leather, whatever the purpose for which the leather is used, the mark is a leprous malignancy, it is unclean.
So he shall burn the garment, whether the warp or the woof, in wool or in linen, or any article of leather in which the mark occurs, for it is a leprous malignancy; it shall be burned in the fire.
The priest shall examine the article with the mark after it has been washed, and if the mark has not changed color, even though the mark has not spread, it is unclean; you shall burn it in the fire; it is a corroding mildew, whether on the top or on the front of it.
This is the law for a leprous disease in a garment of wool or linen, either in the warp or woof, or on anything made of leather, to pronounce it clean or unclean.
When ye come into the land of Canaan, which I give to you for a possession, and I put a leprous plague in a house of the land of your possession,
This is the law for any mark of leprosy—even for a scale,
Any man of the seed of Aaron, and is leprous or hath an issue -- of the holy things he doth not eat till that he is clean; and he who is coming against any uncleanness of a person, or a man whose seed of copulation goeth out from him,
