The Bible says that circumcision takes place at eight days old. Why eight days? Eight days is not
some random amount. There's a reason. The human body has two blood clotting elements. One of them
is called vitamin K. It is not formed in the body up until the fifth to seventh day.
Second clotting factor, which is essential, is called prothrombin. It surprisingly enough
develops to 30 percent of normal by the third day of life and after that peaks at 110 percent
on the eighth day just before leveling off at 100 percent of normal. If vitamin K is not present
when a baby boy is circumcised the baby will bleed to death. The eighth day is the optimum
day for circumcision because the highest presence of the clotting factor vitamin K.
Now of course in today's world we are not commanded to circumcise our male children. I
would just say though that if you're going to do it I would just do things God's way.
Don't wait till they're 12 years old or whatever they generally do here in
the Philippines. Just do it the way that God said it.
