The Bible is so full of these hidden meanings and it's amazing how a person can reread the same book for years and find new information throughout.
The man in this clip describes the story of the Bible saying David chose five smooth stones to use in his slingshot. In the Goliath account David only needed 1 stone to the forehead, so why does the Bible specifically mention 5 stones? Goliath had 4 brothers!
