Medical science has discovered that the blood clotting chemical prothrombin peaks in a newborn on the eighth day. This is therefore the safest day to circumcise a baby. How did Moses know?!

Genesis 17:12 For the generations to come every male among you who is eight days old must be circumcised...

The Bible is a History book, not a Science book, but it is remarkable that where the Bible touches on Science, not only is it correct, but the writer could not have possibly known what he was talking about! How did the writer know these scientific facts? It must have been revealed to him by the Creator of the universe.

The Bible is unlike ANY book ever written. It is, in fact, the Word of God.
