Leviticus 2 gives details of how the Israelites were to bring grain offerings to the Lord. They were to be made from only "fine flour", with oil poured on it, but without any yeast. They were to be brought to the Lord as an offering of the firstfruits. The priest would burn "a handful of the fine flour and oil" as a memorial portion on the fire, producing an aroma pleasing to the Lord. The rest of the grain offering was given to Aaron and his sons as the "most holy part of the offering made to the Lord by fire".
