The Fifth Trumpet

And the shape of the locusts were like horses prepared unto battle; and on their heads were, as it were, crowns like gold, and their faces were like the faces of men. And they had breastplates, as it were breastplates of iron; and the sound of their wings was like the sound of chariots of many horses running to battle. And they had tails like scorpions, and their were stings in their tails; and their power was to hurt men five months.
