Yahweh spoke to Moses and to Aaron, saying, “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. If the bright spot is white in the skin of his body, and its appearance isn’t deeper than the skin, and its hair hasn’t turned white, then the priest shall isolate the infected person for seven days. The priest shall examine him on the seventh day. Behold, if in his eyes the plague is arrested and the plague hasn’t spread in the skin, then the priest shall isolate him for seven more days. The priest shall examine him again on the seventh day. Behold, if the plague has faded and the plague hasn’t spread in the skin, then the priest shall pronounce him clean. It is a scab. He shall wash his clothes, and be clean. But if the scab spreads on the skin after he has shown himself to the priest for his cleansing, he shall show himself to the priest again. The priest shall examine him; and behold, if the scab has spread on the skin, then the priest shall pronounce him unclean. It is leprosy. “When the plague of leprosy is in a man, then he shall be brought to the priest; and the priest shall examine him. Behold, if there is a white swelling in the skin, and it has turned the hair white, and there is raw flesh in the swelling, it is a chronic leprosy in the skin of his body, and the priest shall pronounce him unclean. He shall not isolate him, for he is already unclean. “If the leprosy breaks out all over the skin, and the leprosy covers all the skin of the infected person from his head even to his feet, as far as it appears to the priest,

What current science says

Leprosy (Hansen's disease) is caused by bacteria called Mycobacterium leprae. It spreads through respiratory droplets. Today it can be completely cured with antibiotics. Many 'leprosy' cases in ancient texts were probably other skin conditions they didn't understand.

What the text says

Leviticus 13:1-28 treats leprosy as a matter of ritual impurity, calling for priestly inspection and purification rituals rather than medical treatment.

Three honest ways to read this passage

As history

The text records how its authors understood the world with the knowledge they had. Read this way, a difference from modern science is a window into the ancient mind, not a failure.
As accommodation

The text speaks to its first audience in their own terms, to make a point that isn't mainly about physics or biology. Read this way, the scientific detail is the vehicle, not the cargo.
As contradiction

The text makes a claim about the physical world that modern findings dispute. Read this way, the difference is a genuine factual disagreement worth naming.
