Matthew Poole and continuators on Ezekiel 40:49

49 The length of the porch was twenty cubits, and the breadth eleven cubits, and he brought me by the steps whereby they went up to it: and there were pillars by the posts, one on this side, and another on that side.

Tho' learned men dispute the position of the length, whether from East to West, or from North to South, express word determines the Dimensions of this length and breadth.

Eight say some, others eleven, and some say ten, others say twelve, but most say eight.

So soon as he was come into the Porch, he saw two Pillars, that stood off from the side Walls, not joined to them, as the posts were, much like Iachin and Boaz in Solomons Temple.
