And said, Hitherto shalt thou come - This is a most sublime expression, and its full force can be felt only by one who has stood on the shores of the ocean, and seen its mighty waves roll toward the beach as if in their pride they would sweep everything away, and how they are checked by the barrier which God has made. A voice seems to say to them that they may roll in their pride and grandeur so far, but no further. No increase of their force or numbers can sweep the barrier away, or make any impression on the limits which God has fixed.
And here shall they proud waves be stayed - Margin, as in Hebrew, “the pride of thy waves.” A beautiful image. The waves seem to advance in pride and self-confidence, as if nothing could stay them. They come as if exulting in the assurance that they will sweep everything away. In a moment they are arrested and broken, and they spread out humbly and harmlessly on the beach. God fixes the limit or boundary which they are not to pass, and they lie prostrate at his feet.
