Numbers 18:3-12

³And they shall keep your charges, and the charges of the tabernacle; only they shall not approach the holy vessels and the altar, so both they and you shall not die.

⁴And they shall be joined to you, and shall keep the charges of the tabernacle of witness, in all the services of the tabernacle; and a stranger shall not approach to you.

⁵And you° shall keep the charges of the holy things, and the charges of the altar, and so there shall not be anger amongst the children of Israel.

⁶And I have taken your brethren the Levites out of the midst of the children of Israel, a present given to the Lord, to minister in the services of the tabernacle of witness.

⁷And you and your sons after you shall keep up your priestly ministration, according to the whole manner of the altar, and that which is within the veil; and you° shall minister in the services as the office of your priesthood; and the stranger that comes near shall die.

⁸And the Lord said to Aaron, And, behold, I have given you the charge of the first fruits of all things consecrated to me by the children of Israel; and I have given them to you as an honour, and to your sons after you for a perpetual ordinance.

⁹And let this be to you from all the holy things that are consecrated to me, even the burnt offerings, from all their gifts, and from all their sacrifices, and from every trespass-offering of theirs, and from all their sin-offerings, whatever things they give to me of all their holy things, they shall be your and your sons'.

¹⁰In the most holy place shall you° eat them; every male shall eat them, you and your sons: they shall be holy to you.

¹¹And this shall be to you of the first fruits of their gifts, of all the wave-offerings of the children of Israel; to you have I given them and to your sons and your daughters with you, a perpetual ordinance; every clean person in your house shall eat them.

¹²Every first-offering of oil, and every first-offering of wine, their first fruits of corn, whatever they may give to the Lord, to you have I given them.
