Ezekiel 40:20-23

There was a gate complex on the north side of the wall that was identical to the one on the east (Ezekiel 40:6-16). It too was 50 cubits (83 feet 4 inches) long and 25 cubits (41 feet 8 inches) wide, excluding its stairway. Seven steps led into the gate complex from the outside up to its threshold (Ezekiel 40:6). Looking straight through the north gate or through the east gate one could see, 100 cubits (166 feet 8 inches) beyond (cf. Ezekiel 40:19), another inner gate complex. Ezekiel saw two of these inner gate complexes, one on the north side of the inner courtyard and one on the east side.
