You don’t get it do you. Man says it is inspired by God,man wrote the bible, that doesn’t make it so. You can quote bible passages all day long but it is still what a man said and wrote down.
Oh, I get it. It is a matter of “faith”. Either you believe what is written in the bible or you don't. That is up to you. I believe the bible is true. Therefore since it says right in it that “ALL Scripture is God breathed”, I believe just that. Moses was instructed directly by God to do what he did. It says so in the bible, so yes I believe it.
You don't have to, but it doesn't make you correct.
