PSALMS 77:18-20

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

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

²⁰Thou leddest thy people like a flock, by the hand of Moses and Aaron.
