Wisdom 16:9-11

New Catholic Bible

⁹ For they were slain from the bites of locusts and flies,
    and no remedy was devised to save their lives
    because their punishment by such creatures was well deserved.
¹⁰ However, not even the fangs of venomous snakes could overwhelm your people,
    for your mercy intervened to heal them.
¹¹ They were bitten so that they would be reminded of your decrees,
    and then they were quickly healed
so that they would not fall into profound forgetfulness
    and fail to respond to your kindness.
