Ezekiel 40:17-19

40:17 Then he brought me to the outer court. I saw chambers there, and a pavement made for the court all around; thirty chambers faced the pavement. 40:18 The pavement was beside the gates, corresponding to the length of the gates; this was the lower pavement. 40:19 Then he measured the width from before the lower gate to the front of the exterior of the inner court as 175 feet on the east and on the north.
