In numerous instances the Bible contains medical information that far predates man’s actual discoveries of related principles in the field of medicine. The medical instructions given by Moses to the Israelites some 3500 years ago were not only far superior to the practices of contemporary cultures, they also exceeded medical standards practiced as recently as 100 years ago. Where did Moses get this advanced information? Following are some examples of the medical knowledge afforded the Israelites in biblical times:

Sanitary Practices
For centuries doctors denied the possibility that disease could be transmitted by invisible agents. However, in the late 19th century Louis Pasteur demonstrated in his Germ Theory of Disease that most infectious diseases were caused by microorganisms originating from outside the body. This new understanding of germs and their means of transmission led to improved sanitary standards that resulted in an enormous drop in the mortality rate. Yet these core principles of sanitation were being practiced by the Israelites thousands of years earlier.

The Israelites were instructed to wash themselves and their clothes in running water if they had a bodily discharge, if they came in contact with another person’s discharge, or if they had touched a dead human or animal carcass. They were also instructed to wash any uncovered vessels that were in the vicinity of a dead body, and if a dead carcass touched a vessel it was to be destroyed. Items recovered during war were also to be purified through either fire or running water. In addition, the Israelites were instructed to bury their human waste outside of camp, and to burn the waste of their animals (See Numbers 19:3-22, Lev. 11:1-47; 15:1-33, Deut 23:12).

These sanitary practices without question saved countless lives in the Israelite camps by protecting them against infection caused by unseen germs. Meanwhile, their Egyptian peers were dying by the thousands due to “remedies” that almost always consisted of some amount of human or animal dung1. As mentioned earlier, the sound sanitary practices that we take for granted today only began to flourish about a 100 years ago.

Bacteria
Some time after I wrote these web pages, a Bible skeptic unwittingly showed me yet another example of advanced scientific/medical knowledge in the Bible. He posted a message on a discussion board that ridiculed some verses in Leviticus 13 and 14 that mention leprosy on walls and on garments. He felt this was silly and an error since leprosy is a human disease. What this skeptic was unaware of is the fact that leprosy is a bacteria, a living organism, that certainly can survive on walls and garments! In fact, the Medic-Planet.com encyclopedia noted that leprosy “can survive three weeks or longer outside the human body, such as in dust or on clothing“2. It is no wonder that God commanded the Levitical priests to burn the garments of leprosy victims! (Leviticus 13:52)

Laws of Quarantine
In the same Med-Planet encyclopedia cited above we read that “It was not until 1873 that leprosy could be shown to be infectious rather than hereditary.“2 Of course God knew this all along, as His laws to Moses reveal (Leviticus 13, 14, 22, Numbers 19:20). His instructions regarding quarantine to prevent the spread of leprosy and other infectious diseases are nothing short of remarkable, considering that this life-saving practice was several thousand years ahead of its time. Infected persons were instructed to isolate themselves outside the camp until healed, and were to shave and wash thoroughly. The priests that administered care were instructed to change their clothes and wash thoroughly after inspecting a plague victim.

It should be re-emphasized that the Israelites were the only culture to practice quarantine until the last century, when medical advances finally demonstrated the importance of sanitation and isolation during plagues. The devastating black plague of the 14th century that claimed millions of lives was not broken until the church fathers in Vienna began encouraging the public to start following the guidelines as set forth in the Bible. The promising results in Vienna compelled other cities to follow suit, and the dreaded plague was finally eradicated3.

The First Antiseptic
Hyssop oil was charged by God to Moses to be used as a purifying agent. Hyssop oil has been shown to contain 50% antifungal and antibacterial agents (Numbers 19:18, Psalm 51:7).
