The symmetrical dimensions of the New Jerusalem are most unusual for a city. It is as high as it is long or wide. Interestingly, however, the proportions of the city match those of the Holy of Holies, the inner sanctuary of the temple, the only other cube specifically mentioned in the Bible. As 1 Kings 6:20 states, ‘The inner sanctuary was twenty cubits long, twenty cubits wide, and twenty cubits high.’
