Leviticus 2:4-7

4Now if you bring an offering of grain baked in an oven, it must consist of fine flour, either unleavened cakes mixed with oil or unleavened wafers coated with oil.

5If your offering is a grain offering prepared on a griddle,1 it must be unleavened bread made of fine flour mixed with oil. 6Crumble it and pour oil on it; it is a grain offering.

7If your offering is a grain offering cooked in a pan,2 it must consist of fine flour with oil.
