'Galleries' in the Bible

Then he measured the length of the building facing the courtyard at the rear of the temple, with its galleries on either side as 175 feet. The interior of the outer sanctuary and the porch of the court,

as well as the thresholds, narrow windows and galleries all around on three sides facing the threshold were paneled with wood all around, from the ground up to the windows (now the windows were covered),

Now the upper chambers were narrower, because the galleries took more space from them than from the lower and middle chambers of the building.
