Ezekiel 40:49

49 The length of the porch was twenty cubits and the width eleven cubits; and at the stairway by which it was ascended were columns belonging to the side pillars, one on each side.

Ezekiel 42:6

6 For they were in three stories and had no pillars like the pillars of the courts; therefore the upper chambers were set back from the ground upward, more than the lower and middle ones.
