Deuteronomy 16
6 Ref But in the place marked out by the Lord your God as the resting-place of his name, there you are to put the Passover to death in the evening, at sundown, at that time of the year when you came out of Egypt.
7 Ref It is to be cooked and taken as food in the place marked out by the Lord: and in the morning you are to go back to your tents.
