So I saw that when they awoke, they addressed themselves to go up to the city; but, as I said, the reflection of the sun upon the city (for the city was pure gold) was so extremely glorious that they could not, as yet, with open face behold it, but through an instrument made for that purpose. So I saw, that as I went on, there met them two men, in raiment that shone like gold; also their faces shone as the light. [Rev. 21:18, 2 Cor. 3:18]
