Exodus 13:3-5

Living Bible

³ Then Moses said to the people, “This is a day to remember forever—the day of leaving Egypt and your slavery; for the Lord has brought you out with mighty miracles. Now remember, during the annual celebration of this event you are to use no yeast; don’t even have any in your homes. ^4-5 Celebrate this day of your exodus, at the end of March^[a] each year, when Jehovah brings you into the land of the Canaanites, Hittites, Amorites, Hivites, and Jebusites—the land he promised your fathers, a land ‘flowing with milk and honey.’
