Revelation 9:10

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

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

Then from 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 with heads, and by means of them they wound.
