15Thou hast with thine 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: thine arrows also went abroad. 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.
