Ezekiel 41:13-15

13Then he measured the temple, a hundred cubits long; the separate area and the building with its walls were also a hundred cubits long.

14Also the width of the front of the temple and the separate areas along the east side totaled a hundred cubits.

15He (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.
