Leviticus 6:19

It shall not be baked with yeast. I have given it as their portion of my offerings made by fire. It is most holy, as the sin offering, and as the trespass offering.

Every male among the children of Aaron shall eat of it, as their portion forever throughout your generations, from the offerings of Yahweh made by fire. Whoever touches them shall be holy.

This is the offering of Aaron and of his sons, which they shall offer to Yahweh in the day when he is anointed: the tenth part of an ephah of fine flour for a meal offering perpetually, half of it in the morning, and half of it in the evening.

It shall be made with oil in a griddle. When it is soaked, you shall bring it in. You shall offer the meal offering in baked pieces for a pleasant aroma to Yahweh.
