Two Hundred Million
“And the number of the army of the horsemen were two hundred thousand thousand: and I heard the number of them.” (Rev 9:16 KJV)
The angels that are released from the abyss lead an army that numbers 200,000,000. This army is large enough to destroy a third of the world. There are several possible explanations of their identity. They could be an army of men. Some have suggested that this will be the army of China which will go to war with Israel. They could be an army of world powers that have joined against Israel. The fact they are riding horses could be literal or figurative. The horses could be symbolic of warriors, such as cavalrymen. They could be demons like the locusts of the fifth trumpet. Another possibility is a mixture of the two. They are led by the angels from the bottomless pit to destroy a third of the population.
