Psalms 77:17-21

The clouds poured out water; The skies sounded out; Your arrows flashed here and there.

The sound of Your thunder was in the whirlwind; The lightning lit up the world; The earth trembled and shook.

Your way was in the sea And Your paths in the mighty waters, And Your footprints were not known.

You led Your people like a flock By the hand of Moses and Aaron.
