Commentaries:
Revelation 14, 16, and 19 also speak of the gathering of the nations—in opposition to God—but they are also gathered so that God can judge them all at once. Zephaniah 3:8 also speaks of a devouring fire, an image echoed in II Peter 3:7-12. The context of all this is the Day of the Lord.
