sn Bread made without yeast could be baked quickly, not requiring time for the use of a leavening ingredient to make the dough rise. In Deut 16:3 the unleavened cakes are called “the bread of affliction,” which alludes to the alarm and haste of the Israelites. In later Judaism and in the writings of Paul, leaven came to be a symbol of evil or corruption, and so “unleavened bread”—bread made without yeast—was interpreted to be a picture of purity or freedom from corruption or defilement (S. R. Driver, Exodus, 90–91).
