Exodus 13:5-7

American Standard Version

⁵ And it shall be, when Jehovah shall bring thee into the land of the Canaanite, and the Hittite, and the Amorite, and the Hivite, and the Jebusite, which he sware unto thy fathers to give thee, a land flowing with milk and honey, that thou shalt keep this service in this month. ⁶ Seven days thou shalt eat unleavened bread, and in the seventh day shall be a feast to Jehovah. ⁷ Unleavened bread shall be eaten throughout the seven days; and there shall no leavened bread be seen with thee, neither shall there be leaven seen with thee, in all thy borders.
