the staff of Aaron is a pretty interesting thing. turned into a snake and ate the snakes of the pharoh wizards. Pharaoh wasnt too bright and even after that little demonstration he didn't catch on that he should just let the Israelites go.
also known as "God's Radio" since once a year the high priest would activate it and talk to and listen to God. It was activated by dripping blood from a sacrificed animal. Only one Priest was allowed to perform the ceremony and report the communication. Or so i recall. I mean from scripture, not saying i was there.
Don't forget the "five golden emerods & five golden mice", to commemorate the return of the Ark by the Phillistines.
And good luck finding enough ritually clean Levites of the Families of the Kohathites to man the poles, after it has been properly draped by a consecrated Priest of the Family of Aaron...
**also contains the staff of Aaron, and a sample of manna.***
Not necessarily.
1 Kings 8:9 tells how there was nothing in the ark except the two tablets of stone.
The staff of Aaron and the pot of manna may have been removed and could have been the reason for God punishing the people for looking into the Ark, 1 Sam 6:19.
