Ezekiel 40:17-19

17Then the man brought me into the outer courtyard. I saw rooms there and pavement all around the courtyard. There were 30 rooms along the edge of the pavement.

18The pavement in the lower courtyard ran alongside the gateways. It was as wide as it was long.

19The man measured the distance from the inside of the lower gateway to the outside of the inner courtyard. It was 175 feet from east to north.
