Numbers 18:26-28

Revised Standard Version

²⁶ “Moreover you shall say to the Levites, ‘When you take from the people of Israel the tithe which I have given you from them for your inheritance, then you shall present an offering from it to the Lord, a tithe of the tithe. ²⁷ And your offering shall be reckoned to you as though it were the grain of the threshing floor, and as the fulness of the wine press. ²⁸ So shall you also present an offering to the Lord from all your tithes, which you receive from the people of Israel; and from it you shall give the Lord’s offering to Aaron the priest.
