Ezekiel 42:5-7

Now the upper chambers were shorter, &c. The two upper stories had balconies standing out of them, the breadth of which was taken out of the rooms themselves, and made them so much the narrower, because the weight of the balconies was not supported by pillars, as the rooms over the cloisters were, but only by the wall. The wall that was without, &c., was fifty cubits The wall that enclosed these buildings was commensurate with the breadth of one of the cloisters of the outer court, which were fifty cubits broad. These three verses are allowed by the Jewish Rabbis Solomon and Kimchi to be very difficult to be understood.
