Leviticus 14 · a question people ask
Is this the same disease people call leprosy today?
Leviticus doesn't name any disease we know today, so any match to one goes beyond the text. What the text shows is that its Hebrew word, tsara'at (tap leprosy), covers more than skin. The same word is used for a garment, "the destructive mildew of a garment" (14:55), and for a house, "a spreading mildew in a house" (14:34). The chapter closes by listing what the law covers: "any plague of leprosy, and for an itch, and for the destructive mildew of a garment, and for a house, and for a swelling, and for a scab, and for a bright spot" (14:54-56). The signs the priest looked for on a person are set out in Leviticus 13 (13:2-3).
The verses
““When you have come into the land of Canaan, which I give to you for a possession, and I put a spreading mildew in a house in the land of your possession,”
“This is the law for any plague of leprosy, and for an itch, and for the destructive mildew of a garment, and for a house, and for a swelling, and for a scab, and for a bright spot; to teach when it is unclean, and when it is clean. This is the law of leprosy.”
““When a man shall have a swelling in his body’s skin, or a scab, or a bright spot, and it becomes in the skin of his body the plague of leprosy, then he shall be brought to Aaron the priest or to one of his sons, the priests. The priest shall examine the plague in the skin of the body. If the hair in the plague has turned white, and the appearance of the plague is deeper than the body’s skin, it is the plague of leprosy; so the priest shall examine him and pronounce him unclean.”
