Unleavened bread
In Genesis 19:3 and Exodus 12:15, this indicates something without impurities; for leaven signifies evil and falsity by which celestial and spiritual things become impure and profane. (Arcana Coelestia 2342)
'Unleavened bread' signifies the holiness of love, or the holy of holies. The baking of unleavened bread represents purification.
