All the doors and posts - The doorways, and the posts which formed them, seem to be intended. These were square at top, not arched or rounded. In Assyrian buildings arched doorways were not uncommon. The doorways also, like the windows, exactly faced one another.

And all the doors and posts were square with the windows,.... The doors into the several stories and apartments, and the posts and lintel of them, and the windows over them, were all square:

and light was against light in three ranks; they answered one another as before.

"And all the doorways and mouldings were square of beams" (שׁקף is an accusative of free subordination, denoting the material or the mode of execution; cf. Ewald, 284, a., β). "Square with a straight upper beam" (Thenius) cannot be the correct rendering of שׁקף רבעים. Thenius proposes to read והמּחזת for והמּזוּזת, after the reading αἱ χῶραι of the Seventy, who have also rendered מחזה in 1 Kings 7:4 by χῶρα, a broad space. It may be pleaded in support of this, that רבעים taht , is less applicable to the doorposts or mouldings than to the doorways and outlooks (windows), inasmuch as, if the doorways were square, the square form of the moulding or framework would follow as a matter of course. הפּתחים are both the doors, through which the different rooms were connected with one another, and also those through which the building and its stories were reached, of course by stairs, probably winding staircases, as in the side stories of the temple. The stairs were placed, no doubt, at the front of the building. The height given is thirty cubits, corresponding to that of the whole building (1 Kings 7:2). If we reckon the height of the lower pillars at eight cubits, there were twenty-two cubits left for the stories; and assuming that the roofing of each was one cubit in thickness, there remained eighteen cubits in all for the rooms of the three stories; and this, if equally distributed, would give an internal height of six cubits for each story, or if arranged on a graduated scale, which would probably be more appropriate, a height of seven, six, and five cubits respectively.

And all the doors and posts were square, with the windows: and light was against light in three ranks.

7:5 Windows - He speaks, of smaller windows or lights, which were over the several doors.

doors...: or, spaces and pillars were square in prospect

Margin doors

Or, spaces and pillars were square in prospect.

7:1-12 All Solomon's buildings, though beautiful, were intended for use. Solomon began with the temple; he built for God first, and then his other buildings. The surest foundations of lasting prosperity are laid in early piety. He was thirteen years building his house, yet he built the temple in little more than seven years; not that he was more exact, but less eager in building his own house, than in building God's. We ought to prefer God's honour before our own ease and satisfaction.
