Smiddy3, that’s true.
Many Bible writers were writing things which they did not mean or lost meaning later. For example, epileptic seizures occur because of a sudden surge of electrical activity in the brain, which causes a temporary disturbance in the messaging systems between the brain cells. Unaware of this truth, ancient superstitious people thought such seizures are the result of demon-possessions, hence practiced exorcism. People with such wrong ideas wrote the account of Mark 9:17-29 where we find Jesus is depicted as curing an epileptic patient by casting out demons from him declaring: “This kind can come out only by prayer.” Same type of people are behind projecting Joshua as stopping “the sun and moon” from orbiting (Joshua 10:12) which meant they didn’t know that if the sun stood still, there would have to be a suspension of both our orbital movement as well as our rotational movement in order to keep the sun specifically over one location .
This shows human ideas can make their way into the Bible and may appear as though coming from the mouth of Jesus, or any prophet. So is the case with Moses and his Law.
