Exodus 13:5-7 Catholic Public Domain Version (CPDV)

5. And when the Lord has brought you into the land of the Canaanite, and the Hittite, and the Amorite, and the Hivite, and the Jebusite, which he swore to your fathers that he would give to you, a land flowing with milk and honey, you will celebrate this manner of sacred rites in this month.

6. For seven days, you shall feed on unleavened bread. And on the seventh day, it will be the solemnity of the Lord.

7. You shall consume unleavened bread for seven days. There shall not be seen anything leavened with you, nor in all your parts.
