Leviticus 2:11; Leviticus 2:13

11 "'No grain offering that you bring to ADONAI is to be made with leaven, because you are not to cause any leaven or honey to go up in smoke as an offering made by fire to ADONAI.
13 You are to season every grain offering of yours with salt -do not omit from your grain offering the salt of the covenant with your God, but offer salt with all your offerings.
