1 Kings 7:4 (KJV)

He built also the house of the forest of Lebanon; the length thereof was an hundred cubits, and the breadth thereof fifty cubits, and the height thereof thirty cubits, upon four rows of cedar pillars, with cedar beams upon the pillars.

And it was covered with cedar above upon the beams, that lay on forty five pillars, fifteen in a row.

And there were windows in three rows, and light was against light in three ranks.

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

And he made a porch of pillars; the length thereof was fifty cubits, and the breadth thereof thirty cubits: and the porch was before them: and the other pillars and the thick beam were before them.
