The Cedar used In Building Palaces

Now Hiram king of Tyre sent envoys to David, along with cedar logs, carpenters, and stonemasons, and they built a palace for David.

He built the House of the Forest of Lebanon a hundred cubits long, fifty cubits wide, and thirty cubits high, with four rows of cedar pillars supporting the cedar beams.

The house was roofed with cedar above the beams that rested on the pillars—forty-five beams, fifteen per row.
