Exodus 13:4-6

New Catholic Bible

⁴ This day you came out is in the month of Abib. ⁵ When the Lord brings you to the land of the Canaanites, the Hittites, the Amorites, the Hivites, and the Jebusites, that he swore to your fathers to give you, a land flowing with milk and honey, you shall celebrate this rite in this month.

⁶ “For seven days you shall eat unleavened bread, and on the seventh you shall celebrate a feast in honor of the Lord.
