Ezekiel 41:4 (KJV)

And the breadth of the door was ten cubits; and the sides of the door were five cubits on the one side, and five cubits on the other side: and he measured the length thereof, forty cubits: and the breadth, twenty cubits.

Then went he inward, and measured the post of the door, two cubits; and the door, six cubits; and the breadth of the door, seven cubits.

So he measured the length thereof, twenty cubits; and the breadth, twenty cubits, before the temple: and he said unto me, This is the most holy place.

After he measured the wall of the house, six cubits; and the breadth of every side chamber, four cubits, round about the house on every side.

And the side chambers were three, one over another, and thirty in order; and they entered into the wall which was of the house for the side chambers round about, that they might have hold, but they had not hold in the wall of the house.
