Leprosy

Leprosy is a serious disease for which there used to be no cure in biblical times. It initially led to spots, but then to the death of limbs and finally to death. Due to the risk of infection, those affected had to cry "unclean, unclean" (Gen 13:45) and were cast out of society. Leprosy is a vivid image of sin. The law (Exodus 13 and 14) and the story of the healing of Naaman (2 Kings 5) are very instructive in this regard.
