Why the Eighth Day?


It is a colossal understatement to say that the Bible is unique. It is not just unique, it is of divine origin. This is made obvious by the many instances of scientific foreknowledge found upon its pages.

One example of this concerns the medical practice of circumcision—the act which symbolized the covenant between God and Abraham (Gen. 17:10-14). Circumcision was subsequently incorporated into the Mosaic system and prevailed as a religious requirement until the beginning of the Christian Age (Lev. 12:3; 1 Cor. 7:18.19).

Whereas in the Bible circumcision has a religious importance, studies have shown that this practice has definite health benefits as well. Certain cancer risks are almost completely removed by following this biblical rite. This in itself is impressive; but of even greater significance is the day that the Bible designates for circumcision. Moses wrote: “He that is eight days old shall be circumcised…” (Gen. 17:12). Why the eighth day?

Circumcision, like any surgery, involves risks; bleeding is a concern. A newborn is susceptible to hemorrhaging because he lacks the proper levels of the clotting agent, prothrombin. His body does not produce vitamin K (necessary to produce prothrombin) until between the fifth and seventh days after birth. However, on the eighth day a child’s prothrombin level is higher than at any other time in his life (actually 10% above normal). In other words, the safest possible day to perform circumcision is the eighth (see S.I. McMillen, 1984, None of These Diseases, p. 92).
How did Moses know that the eighth day was right for circumcision—hundreds of years before science discovered it? Was it mere coincidence? Hardly! ~ Brad T. Bromling
