The Outer Court Chambers
17Then he brought me into the aouter court, and behold, there were bchambers and a pavement made for the court all around; thirty chambers 1faced the pavement. 18The pavement (that is, the lower pavement) was by the 1side of the gates, corresponding to the length of the gates. 19Then he measured the width from the front of the alower gate to the front of the exterior of the inner court, 1one bhundred cubits on the east and on the north.
