Charles Ellicott Commentary Exodus 13:3

"And Moses said unto the people, Remember this day, in which ye came out from Egypt, out of the house of bondage; for by strength of hand Jehovah brought you out from this place: there shall no leavened bread be eaten." — Exodus 13:3 (ASV)

Remember this day. —Remembrance was secured in four ways:

1. By the month being made to commence the ecclesiastical year;
2. By the institution of the Passover;
3. By the seven days of unleavened bread;
4. And by the redemption, and the inquiries it would necessitate (Exodus 13:14–15).
