Exodus 12:14-20 and Leviticus 23:5-8 explains the origin and purpose of the Feast of Unleavened Bread. The Feast of Unleavened Bread begins the day after Passover and continues for seven days (sundown, April 4th and ends at sundown, April 11th ). The observance of the Feast of Unleavened Bread is a symbol of our commitment to turn towards righteousness and turn away from sin. During this week-long feast, nothing with leaven in it may be eaten. Abstaining from leavened bread for seven days is symbolic of God’s people separating themselves from sin and turning towards a holy relationship with the Lord. The Lord requires us to clean our homes of any food products that contain leaven, yeast, baking powder, baking soda, or sodium bicarbonate. Foods with leaven include breads, cereals, cakes, pies, crackers, and soups. Read the labels on all of your foods, especially in the pantry and freezer.
