Exodus 13:6-8

Amplified Bible, Classic Edition

⁶ Seven days you shall eat unleavened bread and the seventh day shall be a feast to the Lord.

⁷ Unleavened bread shall be eaten for seven days; no leavened bread shall be seen with you, neither shall there be leaven in all your territory.

⁸ You shall explain to your son on that day, This is done because of what the Lord did for me when I came out of Egypt.
