Deuteronomy 16:6-8

Revised Standard Version Catholic Edition

⁶ but at the place which the Lord your God will choose, to make his name dwell in it, there you shall offer the passover sacrifice, in the evening at the going down of the sun, at the time you came out of Egypt. ⁷ And you shall boil it and eat it at the place which the Lord your God will choose; and in the morning you shall turn and go to your tents. ⁸ For six days you shall eat unleavened bread; and on the seventh day there shall be a solemn assembly to the Lord your God; you shall do no work on it.
