Leviticus 2:2-7

2and bring it to Aaron’s sons the priests. The priest will take a handful of fine flour and oil from it, along with all its frankincense, and will burn this memorial portion of it on the altar, a food offering, a pleasing aroma to the Lord.

3But the rest of the grain offering will belong to Aaron and his sons; it is the holiest part of the food offerings to the Lord.

4“When you present a grain offering baked in an oven, it is to be made 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, it is to be unleavened bread made of fine flour mixed with oil.

6Break it into pieces and pour oil on it; it is a grain offering.

7If your offering is a grain offering prepared in a pan, it is to be made of fine flour with oil.
