Deuteronomy 16:6-8

6You must offer it only at the designated place of worship—the place the Lord your God chooses for his name to be honored. Sacrifice it there in the evening as the sun goes down on the anniversary of your exodus from Egypt.

7Roast the lamb and eat it in the place the Lord your God chooses. Then you may go back to your tents the next morning.

8For the next six days you may not eat any bread made with yeast. On the seventh day proclaim another holy day in honor of the Lord your God, and no work may be done on that day.
