New Defender's Study Bible Notes
20:11 fled away. When the fire from heaven falls on the hosts of Gog and Magog, it will apparently burn up the earth and its atmospheric heaven as well, fulfilling the prophecy of II Peter 3:10. It will purge from the earth all the age-long effects of God’s curse (e.g., the fossil remains of billions of dead creatures that had perished in the great Flood and other subsequent terrestrial catastrophes). In their place will appear God’s awful throne of final judgment. See also Matthew 24:35.
