19 Ref Then, when you take for your food the produce of the land, you are to give an offering lifted up before the Lord.
20 Ref Of the first of your rough meal you are to give a cake for a lifted offering, lifting it up before the Lord as the offering of the grain-floor is lifted up.
21 Ref From generation to generation you are to give to the Lord a lifted offering from the first of your rough meal.
