Ezekiel 46:21-24

Then he brought me back to the outer courtyard and led me to each of its four corners. In each corner I saw an enclosure. Each of these enclosures was 70 feet long and 52-1/2 feet wide, surrounded by walls. Along the inside of these walls was a ledge of stone with fireplaces under the ledge all the way around. The man said to me, “These are the kitchens to be used by the Temple assistants to boil the sacrifices offered by the people.”
