Death by Animals
8. Then I looked and saw a pale horse. Its rider’s name was Death, and Hades followed close behind. And they were given authority over a fourth of the earth, to kill by sword, by famine, by plague, and by the beasts of the earth.
Perhaps we all know that the Black Plague in the 1300's was caused by flea bites to humans from fleas that had been sucking the blood of infected rats, mice, and other ground-dwelling varmints, and the disease was said to have originated in Central and East Asia, thereby traveling the Silk Road to Europe where it killed between 75-200 million Europeans. Africa has suffered from the Ebola outbreak in recent years, and it has its origin in bats. From Africa also came the HIV virus which produces AIDS, and it began in bats and monkeys and was transmitted to humans who ate them or in some way took in the animals' fluids or flesh.
Now, we have the Coronavirus from China, and it is speculated to have originated from bats, when a bat virus was intentionally altered so that humans would be susceptible to it and catch it. In which case, this was a human contrived bio-weapon that was formed from a bat species. In this case, it is humans to blame, but they used an animal to facilitate death to other humans.
Depending on whether locust are considered an animals in Scripture, locusts are currently plaguing India and Africa and devouring the crops, which will cause a food shortage and potential famine. (Zero Hedge article) So beasts of the earth do not necessarily have to attack people in order to kill them; and carrying disease is a far more potent weapon against humanity than rows of teeth and claws.
