Psalms 77:13-20

13Thy way, O God, is in the sanctuary: who is so great a God as our God? 14Thou art the God that doest wonders: thou hast declared thy strength among the people. 15Thou hast with thy arm redeemed thy people, the sons of Jacob and Joseph. Selah. 16The waters saw thee, O God, the waters saw thee; they were afraid: the depths also were troubled. 17The clouds poured out water: the skies sent out a sound: thy arrows also went abroad.1 18The voice of thy thunder was in the heaven: the lightnings lightened the world: the earth trembled and shook. 19Thy way is in the sea, and thy path in the great waters, and thy footsteps are not known. 20Thou leddest thy people like a flock by the hand of Moses and Aaron.
