Deuteronomy 16:6-7

Leeser(i) 6 But at the place which the Lord thy God will choose to let his name dwell in, there shalt thou slay the passover at evening, at the going down of the sun, at the season that thou camest forth out of Egypt. 7 And thou shalt roast and eat it in the place which the Lord thy God will choose; and thou shalt turn in the morning, and go unto thy tents.
