Ezekiel 41:13-14

Ezekiel’s guide next measured the outside walls of the main temple structure. Each was 100 cubits (166 feet 8 inches) from front to back. The distance from the back of the main temple structure to the back of the building behind the temple, including an open space of 20 cubits (33 feet 4 inches) that separated the two structures, was also 100 cubits (166 feet 8 inches). The inner court in front of the temple proper was also 100 cubits (166 feet 8 inches) square.
