Leviticus 7:10-12

10All other grain offerings, whether made of dry flour or flour moistened with olive oil, are to be shared equally among all the priests, the descendants of Aaron.

11“These are the instructions regarding the different kinds of peace offerings that may be presented to the Lord.

12If you present your peace offering as an expression of thanksgiving, the usual animal sacrifice must be accompanied by various kinds of bread made without yeast—thin cakes mixed with olive oil, wafers spread with oil, and cakes made of choice flour mixed with olive oil.
