Psalm 77:18-20

New Revised Standard Version Catholic Edition

¹⁸ The crash of your thunder was in the whirlwind;
    your lightnings lit up the world;
    the earth trembled and shook.
¹⁹ Your way was through the sea,
    your path, through the mighty waters;
    yet your footprints were unseen.
²⁰ You led your people like a flock
    by the hand of Moses and Aaron.
