Leviticus 2:4-7

“If your offering is a grain offering baked in an oven, it must be made of choice flour, but without any yeast. It may be presented in the form of thin cakes mixed with olive oil or wafers spread with olive oil. If your grain offering is cooked on a griddle, it must be made of choice flour mixed with olive oil but without any yeast. Break it in pieces and pour olive oil on it; it is a grain offering. If your grain offering is prepared in a pan, it must be made of choice flour and olive oil.
