Thematic Bible: First fruits of bread

Then it shall be, that, when you eat of the bread of the land, you shall offer up a heave offering unto the LORD. You shall offer up a cake of the first of your dough for a heave offering: as you do the heave offering of the threshingfloor, so shall you offer it up. Of the first of your dough you shall give unto the LORD a heave offering throughout your generations.
