Then measured he the porch of the gate, eight cubits,.... This could not be the length of the porch from gate to gate, or from east to west, as Lipman ; since there were five cubits between every little chamber; but the breadth of it from north to south, and was four yards and two feet over:and the posts thereof two cubits; these were columns or pillars placed on each side of the porch, or at the portal of the gate, of two cubits, or a yard and half a foot thick; which, added to the other eight cubits, made the entrance ten cubits, as in Eze 40:11 what these posts, pillars, or columns signify, see on Eze 40:14:and the porch of the gate was inward; this was the porch of the inward gate; or this was the measure of the porch within the gate.
