Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law. - Matthew 5:18
Every Jot and Tittle: All the Commandments in the Bible
14. Health, Diet, Alcohol, Clothing, and Personal HygieneFour diseases are addressed in the commandments: leprosy, dry itch, freckles, and baldness. In each case a priest makes the diagnosis, determining whether the person is clean or unclean. Unclean people are banished from the community until a priest inspects them and declares them clean again. Before returning to the community, however, a long and bloody ritual must be performed, in which a living bird is dipped into the blood of a dead bird, and the blood is then sprinkled on the person who has been cured of leprosy.
The commandments on diet and alcohol are contradictory. God originally told humans to be vegans; after the flood, he told them to eat anything that moves. In Leviticus, he gave them rules on which animals may or may not be eaten; the New Testament says to ignore those rules and eat whatever you want (except for blood, strangled animals, and animals sacrificed to idols). And the ten commandments on alcohol seem to equally encourage and discourage its use.
The Bible's fashion commandments are hard to summarize, but there are some interesting ones. Always wear white, never wear a garment made from different kinds of fibers, and put some fringes on your garments. Men should not have long hair or round the corners of their beards; women should dress modestly, should not wear men's clothes, braid their hair, or wear expensive jewelry. And no one should have tattoos.
The cleanliness and personal hygiene commandments are mostly about touching unclean things, like the uncleanness of man, a live creeping thing, or a dead beast. But my favorite commandment is this: when you're on a camping trip and you go the bathroom, be sure to cover it up, "for the Lord thy God walketh in the midst of thy camp."
