Deuteronomy 16:7
And thou shalt roast and eat it in the place which the LORD thy God shall choose: and thou shalt turn in the morning, and go unto thy tents. And thou shalt roast and eat it in the place which the LORD thy God shall choose: and thou shalt turn in the morning, and go unto thy tents.
The Passover sacrifice was to be roasted and eaten at the place the Lord chose. In the morning the people were to turn and go back to their tents. This was part of the yearly Passover observance that commemorated God's deliverance of Israel from bondage.
