Leviticus 2:11-13

11“Every grain offering which you present to Adonai shall be made without hametz, for you are not to burn up as smoke any hametz nor any honey as a sacrifice made by fire to Adonai.

12As a gift of firstfruits you may offer them to Adonai, but they are not to ascend for a soothing aroma on the altar.

13Also you are to season with salt every sacrifice of your grain offering. You are never to allow the salt of the covenant of your God to be lacking from your grain offering. With all your sacrifices you must offer salt.
