Revised Standard Version

⁶ And behold, I have taken your brethren the Levites from among the people of Israel; they are a gift to you, given to the Lord, to do the service of the tent of meeting. ⁷ And you and your sons with you shall attend to your priesthood for all that concerns the altar and that is within the veil; and you shall serve. I give your priesthood as a gift,^[a] and any one else who comes near shall be put to death.”
