Psalms 77
17 The clouds poured down water, the heavens resounded with thunder; your arrows flashed back and forth. 18 Your thunder was heard in the whirlwind, your lightning lit up the world; the earth trembled and quaked. 19 Your path led through the sea, your way through the mighty waters, though your footprints were not seen. 20 You led your people like a flock by the hand of Moses and Aaron.
