Revelation 9:4-6

4And it was commanded them that they should not hurt the grass of the earth, neither any green thing, neither any tree; but only those men which have not the seal of God in their foreheads.

5And to them it was given that they should not kill them, but that they should be tormented five months: and their torment was as the torment of a scorpion, when he striketh a man.

6And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them.
