The Grain Offering
11‘No grain offering which you bring to the Lord shall be made with leaven, for you shall burn no leaven nor any honey in any offering to the Lord made by fire. 12As for the offering of the firstfruits, you shall offer them to the Lord, but they shall not be burned on the altar for a sweet aroma. 13And every offering of your grain offering you shall season with salt; you shall not allow the salt of the covenant of your God to be lacking from your grain offering. With all your offerings you shall offer salt.
Leviticus 2:11-13 (NKJV)
