"And I will take away mine hand, and thou shalt see my BACK PARTS: but my face shall not be seen.

So it reads in Exodus, King James Version. Looks to me like God showed Moses his butt. And you're right, the Hebrew still means that.
If the Bible, in translation, is to be taken literally, then God mooned Moses. You see the problem, eh? This is why sensible people do not interpret the Bible literally, but see it for what it is: allegorical tales told to a bunch of nomadic shepherds. Treating the Old Testament as a factual science book is silly. It should not be done.
