Ezekiel 41:3

He brought me to the nave and measured the posts, six cubits wide on the one side and six cubits wide on the other side, which was the width of the tent.

The width of the entrance was ten cubits, and the sides of the entrance were five cubits on the one side, and five cubits on the other side. He measured its length, forty cubits, and the width, twenty cubits.

He measured its length, twenty cubits, and the width, twenty cubits, before the nave. He said to me, “This is the most holy place.”

Then he measured the wall of the house, six cubits; and the width of every side room, four cubits, all around the house on every side.

The side rooms were in three stories, one over another, and thirty in each story. They entered into the wall which belonged to the house for the side rooms all around, that they might be supported and not penetrate the wall of the house.
