Revelation 9:4-6

4They were commanded not to harm the grass of the earth, or any green thing, or any tree, but only those men who do not have the seal of God on their foreheads.

5And they were not given authority to kill them, but to torment them for five months. Their torment was like the torment of a scorpion when it strikes a man.

6In those days men will seek death and will not find it; they will desire to die, and death will flee from them.
