Psalms 77:20 ASV

¹⁸  The voice of thy thunder was in the whirlwind; The lightnings lightened the world: The earth trembled and shook.

¹⁹  Thy way was in the sea, And thy paths in the great waters, And thy footsteps were not known.

²⁰  Thou leddest thy people like a flock, By the hand of Moses and Aaron. Psalm 78 Maschil of Asaph.
