Numbers 18:2–7

And with you bring your brothers also, the tribe of Levi, the tribe of your father, that they may join you and minister to you while you and your sons with you are before the tent of the testimony. They shall keep guard over you and over the whole tent, but shall not come near to the vessels of the sanctuary or to the altar lest they, and you, die. They shall join you and keep guard over the tent of meeting for all the service of the tent, and no outsider shall come near you. And you shall keep guard over the sanctuary and over the altar, that there may never again be wrath on the people of Israel. And behold, I have taken your brothers 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. And you and your sons with you shall guard 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, and any outsider who comes near shall be put to death.”

Bring your fellow Levites from your ancestral tribe to join you and assist you when you and your sons minister before the tent of the covenant law. They are to be responsible to you and are to perform all the duties of the tent, but they must not go near the furnishings of the sanctuary or the altar. Otherwise both they and you will die. They are to join you and be responsible for the care of the tent of meeting—all the work at the tent—and no one else may come near where you are.

“You are to be responsible for the care of the sanctuary and the altar, so that my wrath will not fall on the Israelites again. I myself have selected your fellow Levites from among the Israelites as a gift to you, dedicated to the Lord to do the work at the tent of meeting. But only you and your sons may serve as priests in connection with everything at the altar and inside the curtain. I am giving you the service of the priesthood as a gift. Anyone else who comes near the sanctuary is to be put to death.”

“Bring your relatives of the tribe of Levi—your ancestral tribe—to assist you and your sons as you perform the sacred duties in front of the Tabernacle of the Covenant. But as the Levites go about all their assigned duties at the Tabernacle, they must be careful not to go near any of the sacred objects or the altar. If they do, both you and they will die. The Levites must join you in fulfilling their responsibilities for the care and maintenance of the Tabernacle, but no unauthorized person may assist you.

“You yourselves must perform the sacred duties inside the sanctuary and at the altar. If you follow these instructions, the Lord’s anger will never again blaze against the people of Israel. I myself have chosen your fellow Levites from among the Israelites to be your special assistants. They are a gift to you, dedicated to the Lord for service in the Tabernacle. But you and your sons, the priests, must personally handle all the priestly rituals associated with the altar and with everything behind the inner curtain. I am giving you the priesthood as your special privilege of service. Any unauthorized person who comes too near the sanctuary will be put to death.”

Moreover, bring your brothers with you, the tribe of Levi the tribe of your father, that they may be joined to you and minister to you, you and your sons with you before the tent of testimony. They will keep your responsibility and the responsibility of all the tent, only they may not come near the vessels of the sanctuary and the altar, so both you and they will not die. They will be joined to you, and they will keep the responsibility of the tent of assembly for the entire service of the tent; a stranger may not come near you. You will keep the responsibility of the sanctuary and the responsibility of the altar, and there will no longer be wrath on the Israelites. Look, I myself have chosen your brothers the Levites from the midst of the children. They are a gift to you given from Yahweh to perform the work of the tent of assembly. But you with your sons will keep your priesthood to perform your priestly duties for everything at the altar and for the area behind the curtain. I give you the priesthood as a gift, but the stranger who approaches will be put to death.”

And thy brethren also of the tribe of Levi, the tribe of thy father, bring thou with thee, that they may be joined unto thee, and minister unto thee: but thou and thy sons with thee shall minister before the tabernacle of witness. And they shall keep thy charge, and the charge of all the tabernacle: only they shall not come nigh the vessels of the sanctuary and the altar, that neither they, nor ye also, die. And they shall be joined unto thee, and keep the charge of the tabernacle of the congregation, for all the service of the tabernacle: and a stranger shall not come nigh unto you. And ye shall keep the charge of the sanctuary, and the charge of the altar: that there be no wrath any more upon the children of Israel. And I, behold, I have taken your brethren the Levites from among the children of Israel: to you they are given as a gift for the Lord, to do the service of the tabernacle of the congregation. Therefore thou and thy sons with thee shall keep your priest’s office for every thing of the altar, and within the vail; and ye shall serve: I have given your priest’s office unto you as a service of gift: and the stranger that cometh nigh shall be put to death.
