Both prophecies of Revelation and Joel
tells of creatures having power to injure
but not kill.

"And to them it was given that they should
not kill them but that they should be torm-
ented five months; and their torment was
as the torment of a scorpion when he
striketh a man." Revelation 9:5

The prophecy in Joel, declares that these
creatures shall cause much pain, but they
are not said to kill.

"Before their face the people shall be much
pained: all faces shall gather blackness."
Joel 2:6
