13 What I saw next troubled me deeply: three foul spirits like frogs appeared, belched from the mouth of the dragon, the mouth of the beast, and the mouth of the earth-beast. 14 These frogs are demonic spirits. As they go into the world, they perform miracles persuading the kings of the world to gather for the last battle on the great day of God, the All Powerful.
The dragon, beast, and earth-beast are an unholy trinity who send out demonic spirits. These spirits resemble frogs and remind the reader of the plague of frogs that invaded Egypt before the exodus. These foul spirits roam the world, persuading the kings of the earth to assemble together to do battle against God and His chosen.
A Voice: 15 See, I am coming like a thief! Blessed is the person who watches and waits, dressed and ready to go, so as not to wander about naked, exposed to disgrace.
