Leviticus 2:11

9The priest shall take from the meal offering its memorial, and shall burn it on the altar, an offering made by fire, of a pleasant aroma to the LORD.

10That which is left of the meal offering shall be Aaron’s and his sons’. It is a most holy part of the offerings of the LORD made by fire.

11“‘No meal offering which you shall offer to the LORD shall be made with yeast; for you shall burn no yeast, nor any honey, as an offering made by fire to the LORD.

12As an offering of first fruits you shall offer them to the LORD, but they shall not rise up as a pleasant aroma on the altar.

13Every offering of your meal offering you shall season with salt. You shall not allow the salt of the covenant of your God to be lacking from your meal offering. With all your offerings you shall offer salt.
