Revelation 9:4-6

4They were told not to harm the grass of the earth or any plant or tree, but only those who did not have the seal of God on their foreheads. 5The locusts were not given power to kill them, but only to torment them for five months, and their torment was like the stinging of a scorpion. 6In those days men will seek death and will not find it; they will long to die, but death will escape them.
