The Lord gave many types of laws to the Jewish people. These laws might be put in three categories: 1) Moral, 2) Ceremonial and 3) Civil. Moral laws are perpetual, revealing the character of God and showing us to how treat both God and man. Ceremonial laws have to do with the temple worship, holy days, and sacrificial system. Civil laws have the effect of setting the Jews apart as God’s peculiar people. The laws concerning diseases of the skin seem to fall into the last two categories: ceremonial and civil. The “unclean” condition of one with a skin disease makes them ceremonially unacceptable to take part in corporate worship. And it also makes them a danger to the civil community, as their skin condition may be communicable. The specificity of these “cleanliness” laws is astounding considering that medical science didn’t understand the invisible agents called germs until the late 19th century discoveries of Louis Pasteur. The cleaning of items that came into contact with the individual, the burning of clothes and bedding, the quarantine of the individual until the course of the disease is determined, these are all huge advancements for that day.
