Psalms 77:14-20

Thou art the God that doest wonders: Thou hast made known thy strength among the peoples. Thou hast with thine arm redeemed thy people, The sons of Jacob and Joseph. [Selah The waters saw thee, O God; The waters saw thee, they were afraid: The depths also trembled. The clouds poured out water; The skies sent out a sound: Thine arrows also went abroad. The voice of thy thunder was in the whirlwind; The lightnings lightened the world: The earth trembled and shook. Thy way was in the sea, And thy paths in the great waters, And thy footsteps were not known. Thou leddest thy people like a flock, By the hand of Moses and Aaron.
