Ezekiel 40:17-19

17Then the man brought me through the gateway into the outer courtyard of the Temple. A stone pavement ran along the walls of the courtyard, and thirty rooms were built against the walls, opening onto the pavement.

18This pavement flanked the gates and extended out from the walls into the courtyard the same distance as the gateway entrance. This was the lower pavement.

19Then the man measured across the Temple’s outer courtyard between the outer and inner gateways; the distance was 175 feet.
