NUM22 Do not put frankincense into the meal offering of the suspect wife. Frankincense enhances an offering for it gives it a pleasant fragrance. It is not fitting to enhance the offering of a woman who has sinned and whose moral worth has been called into question. Also, our Sages teach that righteous and modest wives and mothers of our nation are called לבונה (levonah), “frankincense,” but the suspect wife deviated from this path.
