New Defender's Study Bible Notes
20:9 camp of the saints. “The saints” here are probably not just the Israelites in Jerusalem but also the resurrected and raptured saints of the previous ages, all coming to rally around “the beloved city” as the hosts of darkness and their multitudes of human followers surround them for one last desperate attempt to defeat and dethrone the Lord Jesus Christ. This will be impossible, of course, for God (not Satan!) is the Creator of all things, and this time His patience and longsuffering will finally reach an end. In a foretaste of the lake of fire which the rebels will all soon inhabit, God will send from heaven a vast ring of fire around the holy city which will quickly “devour the adversaries” (Hebrews 10:27), “for our God is a consuming fire” (Hebrews 12:29).
