G4451–πύρωσις–purōsis

Dear brothers, do not be surprised, as if it was something strange, if your faith is tested as by fire:

πυρώσει purōsei “fire”

And the kings of the earth, who made themselves unclean with her, and in her company gave themselves up to evil, will be weeping and crying over her, when they see the smoke of her burning,

πυρώσεως purōseōs “burning”

And crying out when they saw the smoke of her burning, saying, What town is like the great town?

πυρώσεως purōseōs “burning”
