The lowest story was 5 cubits (7.5 feet) wide, the middle story
was 6 cubits (9 feet) wide and the third story was 7 cubits
(10.5 feet) wide.
Each story was 5 cubits (7.5 feet) high.
The different widths allowed the beams to rest on the offsets
so that they would not be inserted in the walls of the Temple.
The beams between each story were of cedar and the chambers were
all boarded with cedar wood.
According to the historian Josephus, there were
30 chambers in each story.
1 Chronicles 28:15-16
talked about silver lampstands and silver tables, which we assumed
were to be used by the priests in their quarters.
Although not mentioned in the Scriptures, there would be other furniture
for the priests such as beds, tables, stools, chests, etc.
