Leviticus 2:14-16

14"If you offer a grain offering of firstfruits to the Lord, you shall offer for the grain offering of your firstfruits fresh ears, roasted with fire, crushed new grain.

15And you shall put oil on it and lay frankincense on it; it is a grain offering.

16And the priest shall burn as its memorial portion some of the crushed grain and some of the oil with all of its frankincense; it is a food offering to the Lord.
