Leviticus 2:5-9

And if your offering is a grain offering made on the griddle, it shall be of fine flour, unleavened, mixed with oil;

you shall break it into bits and pour oil on it; it is a grain offering.

Now if your offering is a grain offering made in a pan, it shall be made of fine flour with oil.

When you bring in the grain offering which is made of these things to the Lord, it shall be presented to the priest, and he shall bring it to the altar.

The priest then shall take up from the grain offering its memorial portion, and shall offer it up in smoke on the altar as an offering by fire of a soothing aroma to the Lord.
