Ezekiel 40:18

Render: and the pavement was by the side of the gates, along the length of the gates, to wit, the lower pavement. The pavement is called "lower" because the outer court lay below the level of the inner (Ezekiel 40:34); it extended into the court along the whole length of the gateway, and was therefore (the outer wall being subtracted) 44 cubits broad.
