Deuteronomy 16:3
Amplified Bible (AMP)
You shall eat no leavened bread with it; for seven days you shall eat it with unleavened bread, the bread of affliction--for you fled from the land of Egypt in haste--that all the days of your life you may [earnestly] remember the day when you came out of Egypt.— Deuteronomy 16:3 (AMP)
