Exodus 13:5-7

Amplified Bible, Classic Edition

⁵ And when the Lord brings you into the land of the Canaanites, Hittites, Amorites, Hivites, and Jebusites, which He promised and swore to your fathers to give you, a land flowing with milk and honey [a land of plenty], you shall keep this service in this month.

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.
