And there shall in no wise enter into it any thing that defileth, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb’s book of life. (Revelation 21:27)
Doubtless an allusion to Isa. 52:1. Much of the imagery in John’s description of the Holy City is borrowed from the writings of ancient prophets who described the glories of the Jerusalem that might have been. John is describing the city that will be (see on Eze. 48:35).
