Revelation 9:9

And they had breastplates, as it were breastplates of iron; armed with the best armour of defence. And the sound of their wings was as the sound of chariots of many horses running to battle; like locusts, they moved very swiftly. This agreeth to the Saracens, who made such haste in their conquests, that (saith Mr. Mede) in little more than eighty years they had subdued Palestina, Syria, both the Armenias, almost all the Lesser Asia, Persia, India, Egypt, Numidia, all Barbary, Portugal, Spain; and within a few more, Sicily, Candia, Cyprus, and were come to the very gates of Rome; so as they had many crowns on their heads, and moved as with wings.
