Revelation 9:10

And they had tails like unto scorpions
Locusts are said to have the tail of a serpent, and of the vipers of the earth ^F21; (See Gill on Revelation 9:3), (See Gill on Revelation 9:5). And there were stings in their tails; either in the baser sort of them, the Saracens and Papists; or in their doctrines, the prophet being the tail, ( Isaiah 9:15 ) ; with which both Mahomet, who set himself up for a prophet, and the Romish clergy, who set up their decrees and unwritten traditions above the word of God, have poisoned and destroyed multitudes of souls:

and their power [was] to hurt men five months;
(See Gill on Revelation 9:5).
