Leviticus 2:9-13

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.

The remainder of the grain offering belongs to Aaron and his sons: a most holy part of the offerings to the Lord by fire.

‘No grain offering, which you bring to the Lord, shall be made with leaven, for you shall not offer up in smoke any leaven or any honey as an offering by fire to the Lord.

As an offering of first fruits you shall bring them to the Lord, but they shall not ascend as a soothing aroma on the altar.

Every grain offering of yours, moreover, you shall season with salt, so that the salt of the covenant of your God will not be lacking from your grain offering; with all your offerings you shall offer salt.
