15. By your power you saved your people,the descendants of Jacob and of Joseph.
16. When the waters saw you, O God, they were afraid,and the depths of the sea trembled.
17. The clouds poured down rain;thunder crashed from the sky,and lightning flashed in all directions.
18. The crash of your thunder rolled out,and flashes of lightning lit up the world;the earth trembled and shook.
19. You walked through the waves;you crossed the deep sea,but your footprints could not be seen.
