Psalm 78:43-45

Modern English Version

⁴³ how He had performed His signs in Egypt
    and His wonders in the fields of Zoan:
⁴⁴ and He turned their rivers into blood,
    so that they could not drink from their streams.
⁴⁵ He sent swarms of flies among them, which devoured them,
    and frogs, which destroyed them.
