Leviticus 2:2-4

New International Version - UK

² and take it to Aaron’s sons the priests. The priest shall take a handful of the flour and oil, together with all the incense, and burn this as a memorial^[a] portion on the altar, a food offering, an aroma pleasing to the Lord. ³ The rest of the grain offering belongs to Aaron and his sons; it is a most holy part of the food offerings presented to the Lord.

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.
