 In Exodus 2, it says that Aaron said to them and said, come on, tomorrow we're going to get up, consecrate yourself because we're going to worship the Lord, Yahweh. And so the next day they got up and then we know that Moses came down and God says there's revelry in the camp. And then that day, it's from that part that the Melchizedek priesthood was split between the tribes. And so the Levites, Moses says, who's on my side? And the Levites came to him.
