Numbers 18:1-7 - Provision For The Priesthood

¹ Later, the LORD told Aaron, "You, your sons, and your father's tribe with you are to bear the iniquity of the sanctuary. Also, you and your sons with you are to bear the iniquity of your priesthood. ² Moreover, bring your brothers from your father's tribe of Levi with you, so they may join you and minister to you while you and your sons with you stand in the presence of the Tent of Testimony. ³ They are to take care of your concerns and all the responsibilities involved with the tent. But they're not to approach the holy vessels or the altar. That way, neither you nor they will die. ⁴ They are to join you to maintain services related to the Tent of Meeting, for all the responsibilities involved with the tent. But no unauthorized person is to approach you.

⁵ Take care of the sanctuary and the services of the altar so that there won't be any more wrath on the Israelis. ⁶ Notice that I've taken your brothers, the descendants of Levi, from among the Israelis, giving them to you as a gift from the LORD to perform the service of the Tent of Meeting. ⁷ Now you and your sons with you are to maintain your priestly duties and all matters that concern the altar and what is housed within the veil. You are to perform these services. I'm giving you the priesthood as a gift of service, but any unauthorized person who approaches is to be put to death."
