(And how large will be the locusts described in Revelation 9:7-10 who come out of the bottomless pit? "And the shapes of the locusts were ike unto  horses prepared unto battle; and on their heads were as it were crowns like gold, and their faces were as the faces of men. And they had hair as the hair of women, and their teeth were as the teeth of lions. And they had breasplates, as it were breastplates of iron; and the sound their wings was as the sound of chariots of many horse running to battle. And they had tails like unto scorpions, and there were stings in their tails and their power was to hurt men five months.")
