The city’s ¹  wall is made ²  of jasper and the city is pure gold, like transparent glass. ³ 

Then ¹  I saw something like a sea of glass ²  mixed with fire, and those who had conquered ³  the beast and his image and the number of his name. They were standing ⁴  by ⁵  the sea of glass, holding harps given to them by God. ⁶ 

and in front of the throne was something like a sea of glass, like crystal. ¹  In ²  the middle of the throne ³  and around the throne were four living creatures ⁴  full of eyes in front and in back.

And the twelve gates are twelve pearls – each one of the gates is made from just one pearl! The ¹  main street ²  of the city is pure gold, like transparent glass.
