I agree.
However, a case could be made is my point. Moses was alone. There was no witness. We're told that he never lost his strength. That's an odd thing to say about someone who dies....NEVER lost his strength?
And then there's the odd thing about contending over his body.
And, of course, there's the statement that he died. That pretty well locks it up...unless there are nuances in the Hebrew of that sentence.
My opinion is that Moses is a weak contender as one of the 2 witnesses. He DID appear with Elijah on the Mount of Transfiguration, and Elijah did not die.
Assuredly....very good points....all.
