And you shall present the Levites before the tent of meeting, and assemble the whole congregation of the people of Israel.
And they set the priests in their divisions and the Levites in their courses, for the service of God at Jerusalem, as it is written in the book of Moses.
Then you shall bring Aaron and his sons to the door of the tent of meeting, and shall wash them with water,
and assemble all the congregation at the door of the tent of meeting.”
