I bet we can at least surmise something about it, even if we'll never know its actual meaning for sure in this lifetime. Maybe start by asking questions about frogs that a 1st or 2nd century person living in the Mediterranean might given an answer to. Anything come to mind?
These are some interesting thoughts! I also come to remember the frog plague given through Moses onto Israel.. However I find the splitting of Israel could make sense as well.. Definitely some sort of plague..
It tells us what they are.........[Lying] Spirits that go forth out of the mouths of the A.C., F.P. and Satan to gather {deceive} the nations to do battle against God. The frog, IMHO, tells us they are not powerful demons like Apollyon etc. etc but instead are just Lying Spirits of deception. You ever met people who were REAL GOOD at lying, LOL....they probably have a little green Spirit Frog in them.
