Ezekiel 40:32-34

Then he took me to the east gateway leading to the inner courtyard. He measured it, and it had the same measurements as the other gateways. Its guard alcoves, dividing walls, and entry room were the same size as those of the others, and there were windows along the walls and in the entry room. The gateway passage measured 87-1/2 feet long and 43-3/4 feet wide. Its entry room faced into the outer courtyard. It had palm tree decorations on its columns, and there were eight steps leading to its entrance.
