Exodus 13:6-8

Revised Standard Version Catholic Edition

⁶ Seven days you shall eat unleavened bread, and on the seventh day there shall be a feast to the Lord. ⁷ Unleavened bread shall be eaten for seven days; no leavened bread shall be seen with you, and no leaven shall be seen with you in all your territory. ⁸ And you shall tell your son on that day, ‘It is because of what the Lord did for me when I came out of Egypt.’
