He maketh the storm a calm, so that the waves thereof are still. He maketh the storm a calm - He causes the storm to stand dumb, and hushes the waves. See the original, where sense and sound emphatically meet: -
גליהם ויחשו לדממה סארה יקם galleyhem vaiyecheshu lidemamah searah yakem He shall cause the whirlwind to stand dumb, and he shall hush their billows.
