Ezekiel 40:48,49

And measured each post of the porch By the posts are meant the side-posts, or columns, on each side of the door of entrance: see Ezekiel 40:9; these were measured to be five cubits thick, both on the north and south sides. And the breadth of the gate was three cubits on this side, &c. “Two doors, of three cubits wide, opening each way, formed the entrance; these, with five on each side, called the posts of the porch, amount to sixteen cubits; and the other four may be supposed to have been the distance from these posts to the outside of the walls of the temple.” Scott.
