Numbers 18:6-14

⁶I have given you your brethren the Levites from among the children of Israel, and have delivered them for a gift to the Lord, to serve in the ministries of the tabernacle.

⁷But thou and thy sons look ye to the priesthood: and all things that pertain to the service of the altar, and that are within the veil, shall be executed by the priests. If any stranger shall approach, he shall be slain.

⁸And the Lord said to Aaron: Behold I have given thee the charge of my firstfruits. All things that are sanctified by the children of Israel, I have delivered to thee and to thy sons for the priestly office, by everlasting ordinances.

⁹These therefore shalt thou take of the things that are sanctified, and are offered to the Lord. Every offering, and sacrifice, and whatsoever is rendered to me for sin and for trespass, and becometh holy of holies, shall be for thee and thy sons.

¹⁰Thou shalt eat it in the sanctuary: the males only shall eat thereof, because it is a consecrated thing to thee.

¹¹But the firstfruits, which the children of Israel shall vow and offer, I have given to thee, and to thy sons, and to thy daughters, by a perpetual law. He that is clean in thy house, shall eat them.

¹²All the best of the oil, and of the wine, and of the corn, whatsoever firstfruits they offer to the Lord, I have given them to thee.

¹³All the firstripe of the fruits, that the ground bringeth forth, and which are brought to the Lord, shall be for thy use: he that is clean in thy house, shall eat them.

¹⁴Every thing that the children of Israel shall give by vow, shall be thine.
