Exodus 13:4-6

New Revised Standard Version, Anglicised

⁴ Today, in the month of Abib, you are going out. ⁵ When the Lord brings you into the land of the Canaanites, the Hittites, the Amorites, the Hivites, and the Jebusites, which he swore to your ancestors to give you, a land flowing with milk and honey, you shall keep this observance in this month. ⁶ For seven days you shall eat unleavened bread, and on the seventh day there shall be a festival to the Lord.
