Revelation 9:9 YLT

⁷  And the likenesses of the locusts 'are' like to horses made ready to battle, and upon their heads as crowns like gold, and their faces as faces of men,

⁸  and they had hair as hair of women, and their teeth were as 'those' of lions,

⁹  and they had breastplates as breastplates of iron, and the noise of their wings 'is' as the noise of chariots of many horses running to battle;

¹⁰  and they have tails like to scorpions, and stings were in their tails; and their authority 'is' to injure men five months;

¹¹  and they have over them a king -- the messenger of the abyss -- a name 'is' to him in Hebrew, Abaddon, and in the Greek he hath a name, Apollyon.
