Números 8

“After that, the Levites shall go in to do the service of the Tent of Meeting. You shall cleanse them, and offer them as a wave offering.

Y después de eso vendrán los Levitas á ministrar en el tabernáculo del testimonio: los expiarás pues, y los ofrecerás en ofrenda.

And after that shall the Levites go in to do the service of the tabernacle of the congregation: and thou shalt cleanse them, and offer them for an offering.
