All of this confusion just convinces me more of the man made origin of the Bible. The writers had no idea that their writings would be examined in such detail. They just expected the readers to accept what the writer was stating and move on.
One of my favorite unexplained verses is Judges 1:19. Even though Jehovah was backing Judas in his attempt to drive out the inhabitants of the land he was trying to acquire, he could not because they had chariots of iron. Chariots of iron are stronger than Jehovahs support!
