Revelation 9:3, 5, 10

And out of the smoke locusts came down on the earth and were given power like that of scorpions of the earth.

They were not allowed to kill them but only to torture them for five months. And the agony they suffered was like that of the sting of a scorpion when it strikes.

They had tails with stingers, like scorpions, and in their tails they had power to torment people for five months.
