Numbers 18:24–30

24 For the tithe of the people of Israel, which ethey present as a contribution to the Lord, I have given to the Levites for an inheritance. Therefore I have said of them that they shall have no inheritance famong the people of Israel.”

25 And the Lord spoke to Moses, saying, 26 “Moreover, you shall speak and say to the Levites, ‘When you take from the people of Israel the tithe that I have given you from them for your inheritance, then you shall present a contribution from it to the Lord, ga tithe of the tithe. 27 hAnd your contribution shall be counted to you as though it were the grain of the threshing floor, and as the fullness of the winepress. 28 So you shall also present a contribution to the Lord from all your tithes, which you receive from the people of Israel. And from it you shall give the Lord’s contribution to Aaron the priest. 29 Out of all the gifts to you, you shall present every contribution due to the Lord; from each its best part is to be dedicated.’ 30 Therefore you shall say to them, ‘When you have offered from it the best of it, ithen the rest shall be counted to the Levites as produce of the threshing floor, and as produce of the winepress.
