Wisdom 17:8-10

New Catholic Bible

⁸ for they who had boasted of their power to drive out fears and disorders from sick souls
    were now themselves sick with dread that was ludicrous.
⁹ Even if there was nothing disturbing to frighten them,
    they were panic-stricken because of the crawling vermin and the hissing of snakes,
¹⁰ and, convulsed with terror, they perished,
    even refusing to look upon the air whose presence cannot be avoided.
