Leviticus 2:10-12

New Century Version

¹⁰ The rest of the grain offering belongs to Aaron and the priests. It is a most holy part of the offerings made to the Lord by fire.

¹¹ “‘Every grain offering you bring to the Lord must be made without yeast, because you must not burn any yeast or honey in an offering made by fire to the Lord. ¹² You may bring yeast and honey to the Lord as an offering from the first harvest, but they must not be burned on the altar as a pleasing smell.
