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. 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.
