John Gill's Bible Commentary Ver. 3. And it was covered with cedar above the beams, that lay on forty five pillars, fifteen in a row .] On the second floor were three rows of pillars, fifteen in a row, which made forty five, that stood to east, north, and south; and upon these pillars beams, which were the floor of the third story, over which was a roof of cedar wood.
Matthew Henry Commentary
Verses 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 lai in early piety. He was thirteen years building his house, yet he buil 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.
