And thou shalt bring the Lvim before the tabernacle of the congregation: and thou shalt gather the whole assembly of the children of Yisrael together:
And gather thou all the congregation together unto the door of the tabernacle of the congregation.
And thou shalt bring Aharon and his sons unto the door of the tabernacle of the congregation, and wash them with water.
And they set the kohanim in their divisions, and the Lvim in their courses, for the service of Elohim, which is at Yerushalayim; as it is written in the book of Moshe.
