Ezekiel 42:8

For the chambers on the outer court were fifty cubits long , while those opposite the nave were a hundred cubits long.

While the row of rooms on the side next to the outer court was fifty cubits long, the row on the side nearest the sanctuary was a hundred cubits long.

For the length of the chambers that were in the utter court was fifty cubits : and, lo, before the temple were an hundred cubits.
