The demon-locusts have power to torment
men, and their sting is as that of a scorpion.

A scorpion's sting is known to be one of the
most painful that can be experience but not
necessarially fatal.

It seems foolish that a demon can sting,
but it is recorded of people being bitten by
demons that even attracted world-wide
attention. It shows the amazing powers of
evil spirits under certain conditions.
