Leprosy was a sign of God's punishment in the Bible. It symbolized physical and spiritual uncleanliness. Those who had leprosy were quarantined from the rest of society because they were considered "unclean." In Leviticus, God instructed Moses on how to deal with those who had leprosy. They were to be moved outside of the camp and their clothes were to be torn. They were not to return until they were healed. Lepers were also excluded from worshiping in the temple. They could not participate in religious festivals or offer sacrifices. If they did come into contact with someone, they had to shout, "Unclean! Unclean!" The penalty for not following these rules was death.
