Deuteronomy 16:7-9

New International Reader's Version

⁷ Cook the animal and eat it. Do it at the place the Lord your God will choose. Then in the morning return to your tents. ⁸ For six days eat bread made without yeast. On the seventh day come together for a service to honor the Lord your God. Don’t do any work on that day.

The Feast of Weeks

⁹ Count off seven weeks from the time you begin to cut your grain in the field.
