Numbers 18:26-32 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.

CAB⁽ⁱ⁾ 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. ³⁰ And you shall say to them, When you shall offer the firstfruits from it, then shall it be reckoned to the Levites as produce from the threshing floor, and as produce from the winepress. ³¹ And you shall eat it in any place, you and your families; for this is your reward for your services in the tabernacle of witness. ³² And you shall not bear sin by reason of it, for you shall have offered an offering of firstfruits from it, and you shall not profane the holy things of the children of Israel, that you die not.
