Numbers 15:19-21

New Revised Standard Version, Anglicised

¹⁹ whenever you eat of the bread of the land, you shall present a donation to the Lord. ²⁰ From your first batch of dough you shall present a loaf as a donation; you shall present it just as you present a donation from the threshing-floor. ²¹ Throughout your generations you shall give to the Lord a donation from the first of your batch of dough.
