Exodus 13:4-6

Revised Standard Version

⁴ This day you are to go forth, in the month of Abib. ⁵ And when the Lord brings you into the land of the Canaanites, the Hittites, the Amorites, the Hivites, and the Jeb′usites, which he swore to your fathers to give you, a land flowing with milk and honey, you shall keep this service in this month. ⁶ Seven days you shall eat unleavened bread, and on the seventh day there shall be a feast to the Lord.
