Deuteronomy 16:6-8

New Catholic Bible

⁶ Do it only in the place that the Lord, your God, has chosen to place his name. You will make the Passover sacrifice in the evening, when the sun goes down, at the time when you went forth out of Egypt. ⁷ Roast the lamb and eat it in the place that the Lord, your God, will choose. Then, in the morning, return to your homes. ⁸ For six days you are to eat unleavened bread. Then, on the seventh day, you will hold a solemn assembly to the Lord, your God, and you are to do no heavy labor.
