The Bible and Laws of Quarantine
Long before medical science discovered the importance of quarantine of persons with infectious diseases, the Bible instigated them. In 1490 B.C. the Scriptures tell the children of Israel what to do if a man has leprosy: "All the days wherein the plague shall be in him he shall be defiled; he is unclean: he shall dwell alone; without the camp shall his habitation be" (Leviticus 13:46). Laws of quarantine were not instigated by modern man until the seventeenth century.
"During the devastating Black Death of the fourteenth century, patients who were sick or dead were kept in the same rooms as the rest of the family. People often wondered why the disease was affecting so many people at one time. They attributed these epidemics to "bad air" or "evil spirits." However, careful attention to the medical commands of God as revealed in Leviticus would have saved untold millions of lives. Arturo Castiglione wrote about the overwhelming importance of this biblical medical law: "The laws against leprosy in Leviticus 13 may be regarded as the first model of sanitary legislation" (
