It's a good example of yet another reason for not taking the bible as factual truth, word for word, especially from the context of a modern person's mind, much less even the minds of 8th century Europeans (council of Nicea).
It's why Revelations doesn't make any sense, even by biblical standards. Many Hebrew scholars are almost sure it was ethnic folklore, catch phrases and metaphors used as a secret code to keep far flung protochristian Jewish conclaves informed about early church business, and any threats from within or from Roman officials acting against them. It would not be decipherable to outsiders if they intercepted any of these letters of correspondence. Too bad so much of old Hebrew culture and early Christian idioms are lost in time, or we could figure out what the messages hidden in Revelations were actually about.
