Leviticus 2:3-5

New Century Version

³ The rest of the grain offering will belong to Aaron and the priests; it is a most holy part of the offerings made by fire to the Lord.

⁴ “‘If you bring a grain offering that was baked in the oven, it must be made from fine flour. It may be loaves made without yeast and mixed with oil, or it may be wafers made without yeast that have oil poured over them. ⁵ If your grain offering is cooked on a griddle, it must be made, without yeast, of fine flour mixed with oil.
