Revelation 9:3-5

3Then out of the smoke came locusts onto the earth, and they were given power like that of the scorpions of the earth.

4They were told not to damage the grass of the earth, or any green plant or tree, but only those people who did not have the seal of God on their forehead.

5The locusts were not given permission to kill them, but only to torture them for five months, and their torture was like that of a scorpion when it stings a person.
