Leviticus 2:11

Without leaven or honey. No leaven or honey was to be used in the sacrifice offered to God: to signify that we are to exclude from the pure worship of the gospel, all double-dealing and affection to carnal pleasures. (Challoner) --- The prohibition of leaven regarded these sacrifices. It was offered with the first-fruits, (chap. xxiii. 17,) and perhaps also in peace-offerings, chap. vii. 13. Honey is here rejected, as incompatible with the other ingredients, to admonish us to lead a penitential life, and to keep at a greater distance from the customs of the pagans, who generally accompanied their oblations with honey, Ezechiel xvi. 18. Herodotus (B. ii.) says, the Egyptians used honey in sacrifice. (Calmet) --- By unleavened bread, the Hebrews were reminded of their flight out of Egypt; and by refraining from honey, they were taught to act like men. (Menochius)
