Leviticus 2:11-13

11No meat offering, which ye shall bring unto the Lord, shall be made with leaven: for ye shall burn no leaven, nor any honey, in any offering of the Lord made by fire.

12As for the oblation of the firstfruits, ye shall offer them unto the Lord: but they shall not be burnt on the altar for a sweet savour.1 13And every oblation of thy meat offering shalt thou season with salt; neither shalt thou suffer the salt of the covenant of thy God to be lacking from thy meat offering: with all thine offerings thou shalt offer salt.
