Wisdom 18:11-13

New Catholic Bible

¹¹ The slave received the same punishment as the master,
    and now commoner and king had to endure identical sufferings.
¹² And all alike, afflicted by the same form of death,
    had corpses too many to count.
For there were not enough who were left alive to bury the dead,
    since in a single instant their most precious offspring had been destroyed.
¹³ Formerly they had disbelieved everything as a result of their sorceries,
    but at the destruction of their firstborn they acknowledged this people to be the offspring of God.
