Consider the Bible's coverage of another field: health and
sanitation. If an Israelite had a skin blemish suspected of being
leprosy, he was put in isolation. "All the days that the plague is in
him he will be unclean. He is unclean. He should dwell isolated.
Outside the camp is his dwelling place." (Leviticus 13:46) Even
infected garments were burned. (Leviticus 13:52) In those days, this
was an effective way of preventing the spread of the infection.

Another important law had to do with the disposal of human
excrement, which had to be buried outside the camp. (Deuteronomy
23:12, 13) This law no doubt saved Israel from many sicknesses. Even
today, severe health problems are caused in some lands by the
improper disposal of human wastes. If people in those lands would
only follow the law written down thousands of years ago in the Bible,
they would be much healthier.

The Bible's high standard of hygiene even involved mental health.
A Bible proverb said: "A calm heart is the life of the fleshly
organism, but jealousy is rottenness to the bones." (Proverbs 14:30)
In recent years, medical research has demonstrated that our physical
health is indeed affected by our mental attitude. For example, Doctor
C. B. Thomas of Johns Hopkins University studied more than a thousand
graduates over a period of 16 years, matching their psychological
characteristics with their vulnerability to diseases. One thing she
noted: The graduates most vulnerable to disease were those who were
angrier and more anxious under stress.
