Numbers 18:24 bbe — For the tenths which the children of Israel give as a lifted offering to the Lord I have given to the Levites as their…

And to the children of Levi I have given as their heritage all the tenths offered in Israel, as payment for the work they do, the work of the Tent of meeting.

In future the children of Israel are not to come near the Tent of meeting, so that death may not come to them because of sin.

But the Levites are to do the work of the Tent of meeting, and be responsible for errors in connection with it: this is a law for ever through all your generations; and among the children of Israel they will have no heritage.

And the Lord said to Moses,

Say to the Levites, When you take from the children of Israel the tenth which I have given to you from them as your heritage, a tenth part of that tenth is to be offered as an offering lifted up before the Lord.

And this lifted offering is to be put to your credit as if it was grain from the grain-floor and wine from the vines.
