Psalm 78:51-53

Revised Standard Version Catholic Edition

⁵¹ He smote all the first-born in Egypt,
    the first issue of their strength in the tents of Ham.
⁵² Then he led forth his people like sheep,
    and guided them in the wilderness like a flock.
⁵³ He led them in safety, so that they were not afraid;
    but the sea overwhelmed their enemies.
