• Numbers 8:15-19
    After that the Levites shall go in to service the tabernacle of meeting. So you shall cleanse them and offer them like a wave offering. For they are wholly given to Me from among the children of Israel; I have taken them for Myself instead of all who open the womb, the firstborn of all the children of Israel. For all the firstborn among the children of Israel are Mine, both man and beast; on the day that I struck all the firstborn in the land of Egypt I sanctified them to Myself. I have taken the Levites instead of all the firstborn of the children of Israel. And I have given the Levites as a gift to Aaron and his sons from among the children of Israel, to do the work for the children of Israel in the tabernacle of meeting, and to make atonement for the children of Israel, that there be no plague among the children of Israel when the children of Israel come near the sanctuary.”
     
  • Numbers 16:7-10
    put fire in them and put incense in them before the LORD tomorrow, and it shall be that the man whom the LORD chooses is the holy one. You take too much upon yourselves, you sons of Levi!” Then Moses said to Korah, "Hear now, you sons of Levi: Is it a small thing to you that the God of Israel has separated you from the congregation of Israel, to bring you near to Himself, to do the work of the tabernacle of the LORD, and to stand before the congregation to serve them; and that He has brought you near to Himself, you and all your brethren, the sons of Levi, with you? And are you seeking the priesthood also?
