Leviticus 2:1-2

1“When anyone presents a grain offering as an offering to the Lord, it is to consist of fine flour. He is to pour olive oil on it, put frankincense on it,

2and bring it to Aaron’s sons the priests. The priest will take a handful of fine flour and oil from it, along with all its frankincense, and will burn this memorial portion of it on the altar, a food offering, a pleasing aroma to the Lord.
