Leviticus 2:2-4

Common English Bible

² then bring it to Aaron’s sons, the priests. A priest will take a handful of its choice flour and oil, along with all of its frankincense, and will completely burn this token portion on the altar as a food gift of soothing smell to the Lord. ³ The rest of the grain offering belongs to Aaron and his sons as a most holy portion from the Lord’s food gifts.

⁴ When you present a grain offering baked in an oven, it must be of choice flour: unleavened flatbread mixed with oil or unleavened wafers spread with oil.
