Numbers 18:7 BBE

⁵  You are to be responsible for the holy place and the altar, so that wrath may never again come on the children of Israel.

⁶  Now, see, I have taken your brothers the Levites from among the children of Israel: they are given to you and to the Lord, to do the work of the Tent of meeting.

⁷  And you and your sons with you are to be responsible as priests for the altar and everything on it, and everything inside the veil; you are to do the work of priests; I have given you your position as priests; and any other man who comes near will be put to death.

⁸  And the Lord said to Aaron, See, I have given into your care my lifted offerings; even all the holy things of the children of Israel I have given to you and to your sons as your right for ever, because you have been marked with the holy oil.

⁹  This is to be yours of the most holy things, out of the fire offerings; every offering of theirs, every meal offering and sin-offering, and every offering which they make on account of error, is to be most holy for you and your sons.
