Ezekiel 40:32-37

The Measurements of the East and North Gates of the Inner Court.

‘And he brought me to the inner court towards the east, and he measured the gate in accordance with these measurements, and its side rooms, and its posts, and its colonnades, in accordance with these measurements. And there were windows in it and in the colonnades round about. It was fifty cubits long and twenty five cubits broad. And its colonnades were towards the outer court, and palm trees were on its posts, on this side and on that side. And the ascent to it had eight steps. And he brought me to the north gate, and he measured it according to these measurements, its side rooms, and its posts, and its colonnades. And there were windows in it round about. The length was fifty cubits, and the breadth twenty five cubits. And its posts were towards the outer court, and the palm trees were on its posts, on this side and on that side. And the ascent to it had eight steps.'

All that has been said about the south gate applies in threefold measure (north, south and east).
