Let's see how many apologetics take the bait

[Pat Mustard]

There is an unstated premise that needs explicit stating if there is to be a clear distinction of the difficulty.

Here's what I think it is: All of God's commands in the bible are valid and binding for every person and in every age.

If that premise is true, then "contradictions" like the OP show that the commands of God as recorded in the Bible are unreliable.

If that is the unstated premise, where does it come from? If not, what is the premise?

Why would the perfect being, the omnipotent god, not make laws that were binding on everybody for all time? Why would he create laws that were later superseded and improved upon, thus calling into severe question his perfection (as he had created something imperfect)?
