Ezekiel 40:48  (King James Version)
And he brought me to the porch of the house, and measured each post of the porch, five cubits on this side, and five cubits on that side: and the breadth of the gate was three cubits on this side, and three cubits on that side.

the porch
The length of the porch was twenty cubits, the same as the breadth of the temple, and the breadth eleven cubits, that is, one cubit more than in Solomon's temple. Two bivalve, or folding doors, each leaf of them being three cubits wide, seem to have formed the entrance; which, with five cubits, perhaps of brick or stone work, one each side, called "the post of the porch," amount to sixteen cubits; and the other four cubits may be supposed to have been the distance from these posts to the outside walls of the temple.
