1 Kings 7:2-3

2He also built the House of the Forest of Lebanon; its length was a hundred cubits (150 ft.), its width fifty cubits (75 ft.), and its height thirty cubits (45 ft.), upon four rows of cedar pillars, with cedar beams upon the pillars.

3And it was covered with cedar [as a roof] on the supporting beams that were upon the forty-five pillars, fifteen in each row.
