Revelation 9:10

They have tails like scorpions, and stings, and their power to hurt men for five months lies in their tails.

They were allowed to torture them for five months, but not to kill them, and their torture was like the torture of a scorpion, when it stings a man.

Then out of the smoke came locusts on the earth, and they were given power like the power of scorpions of the earth.

For the power of the horses is in their mouths and in their tails; for their tails are like serpents and have heads, and with them they do harm.
