Thematic Bible: First fruits of bread

Then, when you eat of the food of the land, you shall set apart a portion for a gift to the Lord [called a heave or taken-out offering]. You shall set apart a cake made of the first of your coarse meal as a gift [to the Lord]; as an offering set apart from the threshing floor, so shall you lift it out or heave it. Of the first of your coarse meal you shall give to the Lord a portion for a gift throughout your generations [your heave or lifted-out offering].
