Ezekiel 41:2-4

2The width of the entrance was ten cubits. The sides of the entrance were five cubits on the one side and five cubits on the other side. He measured its length, 40 cubits and its width, 20 cubits.

3He went to the inner room and measured each pillar of the entrance, two cubits; the doorway, six cubits; and the width of the doorway, seven cubits.

4When he measured the inner room’s length, it was 20 cubits, and the width was 20 cubits, in front of the Temple. He said to me, “This is the Holy of Holies.”
