Numbers 18:27-29

Complete Jewish Bible

²⁷ The gift you set aside will be accounted to you as if it were grain from the threshing-floor and grape juice from the wine vat. ²⁸ In this way you will set aside a gift for Adonai from all your tenths that you receive from the people of Isra’el, and from these tenths you are to give to Aharon the cohen the gift set aside for Adonai. ²⁹ From everything given to you, you are to set aside all that is due Adonai, the best part of it, its holy portion.’
