Leviticus 2:4-6

4“ ‘If you bring a grain offering baked in an oven, it is to consist of the finest flour: either thick loaves made without yeast and with olive oil mixed in or thin loaves made without yeast and brushed with olive oil. 5If your grain offering is prepared on a griddle, it is to be made of the finest flour mixed with oil, and without yeast. 6Crumble it and pour oil on it; it is a grain offering.
