במדבר, פרק כ״ח, פסוק י״ג

Every animal sacrifice is accompanied by a specific measure of fine flour mixed with oil. This grain offering serves as an essential complement to the animal itself. Together, they are given over to the fire of the altar as a complete expression of national devotion.

The various elements of this sacrifice carry deep symbolic and practical meaning [רש ר הירש]. Elevating it entirely as a burnt offering expresses a unified purpose, symbolizing an oath and a deep desire to rise to the spiritual heights that God has set. The pleasing odor it creates reflects God's satisfaction, which is ultimately meant to be realized in a person's practical, everyday actions. Finally, giving the sacrifice over to the fire represents drawing close to God through absolute devotion to the purifying, life-giving, and guiding power of His laws.
