Leviticus 2:1-2, 4-5, 15-16

“When anyone brings a grain offering as an offering to the LORD, his offering shall be of fine flour. He shall pour oil on it and put frankincense on it and bring it to Aaron’s sons the priests. And he shall take from it a handful of the fine flour and oil, with all of its frankincense, and the priest shall burn this as its memorial portion on the altar, a food offering with a pleasing aroma to the LORD.

“When you bring a grain offering baked in the oven as an offering, it shall be unleavened loaves of fine flour mixed with oil or unleavened wafers smeared with oil. And if your offering is a grain offering baked on a griddle, it shall be of fine flour unleavened, mixed with oil.

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