Leviticus 2:11-13

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

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