Ezekiel 40:48-49

48Then he brought me to the porch of the temple, and he measured each side pillar of the porch, five cubits on each side; and the width of the gate was three cubits on each side.

49The length of the porch was twenty cubits and the width eleven cubits; and at the stairway by which it was ascended, there were [two] columns beside the side pillars, one on each side [of the entrance].
