The number of soldiers on horseback was 200,000,000; I heard their number.
The WoF would likely think: 200,000,000 times 10 percent. $$$ Jets, jets everywhere.
But what must the 1st century reader of this think? I mean the entire Roman Empire is estimated to be between 45 to 120 million at its peak. This is counting 5 year olds, wherein "half of the Roman subjects died by the age of 5" (Wiki-Demography of the Roman Empire). Must have been from putting them on horseback for Rev 9.
