Psalms 136:15

Psalms 136:15. But overthrew Pharaoh and his host in the Red sea: for his mercy endureth for ever.

This is the deep bass of the hymn, he "overthrew Pharaoh." "The horse and his rider hath he thrown into the sea." We cannot give up that verse; we cannot refuse to sing the song of Moses; we must praise and bless God for all that he did at the Red Sea, even though terrible were his deeds of righteousness, when the chivalry of Egypt sank to the bottom of the sea like a stone.
