While the anatomic version of the word "foreskin" includes the entire covering of the glans (outlined in red),
the Scriptural version is quite different.  Based on Scripture and the historical evidence, "foreskin" in the
Hebrew vernacular means only what is described as "overhang" in this rendering, the skin at the
fore end of
the penis.  If I sent you "aforedeck" it would mean to the bow, the front of the ship, not amidship, the middle
half.  When a golfer yells "FORE!!!" it is a warning to the people beFORE him, not beside or behind him.
Foreskin.  Makes sense doesn't it?
What is a foreskin?
