The waters saw you, O God, the waters saw you and writhed; the very depths were convulsed. The clouds poured down water, the skies resounded with thunder; your arrows flashed back and forth. Your thunder was heard in the whirlwind, your lightning lit up the world; the earth trembled and quaked. Your path led through the sea, your way through the mighty waters, though your footprints were not seen. You led your people like a flock by the hand of Moses and Aaron (Psalm 77:16-20).
