Revelation 9:3-5

3Then out of the smoke came locusts upon the earth, and power [to hurt] was given to them, like the power which the earth’s scorpions have.

4They were told not to hurt the grass of the earth, nor any green thing, nor any tree, but [to hurt] only the people who do not have the seal (mark of ownership, protection) of God on their foreheads.

5They were not permitted to kill anyone, but to torment and cause them extreme pain for five months; and their torment was like the torment from a scorpion when it stings a man.
