Revelation 9:4-6

4They knew that they must not do anything bad to the grass on the earth. They must not attack any plant or any tree. They could only attack people who did not have God's seal on the front of their heads.

5The locusts did not have authority to kill those people. But they could cause them very bad pain for five months. Their pain was like the great pain from a scorpion when it hurts someone.

6During that time of great pain, people will want to kill themselves. They will want to die, but they will not find any way to die.
