Exodus 13:6-8

New Revised Standard Version, Anglicised Catholic Edition

⁶ For seven days you shall eat unleavened bread, and on the seventh day there shall be a festival to the Lord. ⁷ Unleavened bread shall be eaten for seven days; no leavened bread shall be seen in your possession, and no leaven shall be seen among you in all your territory. ⁸ You shall tell your child on that day, “It is because of what the Lord did for me when I came out of Egypt.”
