Ezekiel 41:2-4

2And the breadth of the entry was ten cubits, and the sides of the entry were five cubits on this side, and five cubits on that side; and he measured its length, forty cubits, and the breadth, twenty cubits.

3And he went inwards, and measured the post of the entry, two cubits; and the entry, six cubits; and the breadth of the entry, seven cubits.

4And he measured its length, twenty cubits; and the breadth, twenty cubits, before the temple: and he said unto me, This is the most holy [place].
