Ezekiel 41:13-15

Then he measured the temple, a hundred cubits long; the separate area and the building with its walls were also a hundred cubits long. Also the width of the front of the temple and the separate areas along the east side totaled a hundred cubits. He (the angel) measured the length of the building along the front of the separate area behind it, with a gallery on each side, a hundred cubits; he also measured the inner sanctuary and the porches (porticoes) of the courtyard.
