Exodus 13:3-5 New Revised Standard Version, Anglicised Catholic Edition (NRSVACE)
The Festival of Unleavened Bread
3 Moses said to the people, ‘Remember this day on which you came out of Egypt, out of the house of slavery, because the Lord brought you out from there by strength of hand; no leavened bread shall be eaten. 4 Today, in the month of Abib, you are going out. 5 When the Lord brings you into the land of the Canaanites, the Hittites, the Amorites, the Hivites, and the Jebusites, which he swore to your ancestors to give you, a land flowing with milk and honey, you shall keep this observance in this month.
