Leviticus 2:2-7

2He shall then bring it to Aaron’s sons the priests; and he shall take from it 1his handful of its fine flour and of its oil, with all of its frankincense. And the priest shall offer it up in smoke as its 2memorial portion on the altar, an offering by fire of a soothing aroma to the Lord. 33The remainder of the grain offering belongs to 4Aaron and his sons: a most holy part of the offerings to the Lord by fire.

4‘Now when you bring an offering of a grain offering baked in an oven, it shall be 5unleavened cakes of fine flour mixed with oil, or unleavened wafers 6spread with oil. 5And if your offering is a grain offering made 7on the griddle, it shall be of fine flour, unleavened, mixed with oil; 6you shall break it into bits and pour oil on it; it is a grain offering. 7Now if your offering is a grain offering made 8in a 9pan, it shall be made of fine flour with oil.
