Numbers 18:21-29 And behold, I have given to the sons of Levi every tithe in Israel for an inheritance for their services, the work in which they perform in the tabernacle of witness.

CAB⁽ⁱ⁾ ²¹ And behold, I have given to the sons of Levi every tithe in Israel for an inheritance for their services, the work in which they perform in the tabernacle of witness. ²² And the children of Israel shall no more draw near to the tabernacle of witness to incur fatal guilt. ²³ And the Levite himself shall perform the service of the tabernacle of witness; and they shall bear their iniquities, it is a perpetual statute throughout their generations; and in the midst of the children of Israel they shall not receive an inheritance. ²⁴ Because I have given as a distinct portion to the Levites for an inheritance the tithes of the children of Israel, whatsoever they shall offer to the Lord; therefore I said to them, In the midst of the children of Israel they shall have no inheritance. ²⁵ And the Lord spoke to Moses, saying, ²⁶ You shall also speak to the Levites, and shall say to them, If you take the tithe from the children of Israel, which I have given you from them for an inheritance, then shall you separate from it a heave offering to the Lord, a tenth of the tenth. ²⁷ And your heave offerings shall be reckoned to you as grain from the threshing floor, and an offering from the winepress. ²⁸ So shall you also separate them from all the offerings of the Lord out of all your tithes, whatsoever you shall receive from the children of Israel; and you shall give to them of the Lord's offering, to Aaron the priest. ²⁹ Of all your gifts you shall offer an offering to the Lord, and of every firstfruit the consecrated part from it.
