Exodus 13:3-5

3And Moses said to the people, Remember this day, when ye came out from Egypt, out of the house of bondage; for by strength of hand the LORD brought you out from this place : there shall no leavened bread be eaten.1

4This day in the month Abib, ye came out.

5And it shall be when the LORD shall bring thee into the land of the Canaanites, and the Hittites, and the Amorites, and the Hivites, and the Jebusites, which he swore to thy fathers to give thee, a land flowing with milk and honey, that thou shalt keep this service in this month.
