G4451–πύρωσις–purōsis

Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you:

πυρώσει purōsei “fire”

And the kings of the earth, who have committed fornication and lived deliciously with her, shall bewail her, and lament for her, when they shall see the smoke of her burning,

πυρώσεως purōseōs “burning”

And cried when they saw the smoke of her burning, saying, What city is like unto this great city!

πυρώσεως purōseōs “burning”
