Interesting is that indeed the scriptures state Moses body was hidden. Israel surely would have made some sort of hommage, alter, or idol of Moses...they were not yet purged from their former beliefs which were often paganish, bad habits take time to break.
But nothing is stated of Mary in that respect...so she certainly wasn’t seen in God’s eyes as worthy to have her body hidden....nor that she assended either...which then pretty much concludes she is in the ground as far as her body is concerned.
I was speaking to the paucity of info in the scriptures as to the final resting places of the various saints and heros of the Bible and likening that to God Hiding Moses body. The Holy Spirit simply didn’t want that info known to future readers of the Bible.
