Revelation 9:4-6

4They were told not to harm the grass of the earth, or any green plant, or any tree, but only those people who do not have God’s seal on their foreheads.

5They were not permitted to kill them but were to torment them for five months; their torment is like the torment caused by a scorpion when it stings someone.

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