Ezekiel 41:4-6

Revised Geneva Translation

⁴ So he measured its length and the width before the Temple (twenty cubits by twenty cubits), and he said to me, “This is the Most Holy Place.”

⁵ Afterward, he measured the wall of the House (six cubits) and the width of every chamber (four cubits) all around the House, on every side.

⁶ And the chambers were in three stories, one above the other, thirty chambers in each story. And they entered into the walls made for the chambers, which was all around the House, so that the posts might be fastened to them and not be fastened to the wall of the House.
