'Foam' in the Bible

“Behind him he makes a shining wake;One would think the deep to be gray-haired [with foam].

Though its waters roar and foam,Though the mountains tremble at its roaring. Selah.

As for Samaria, her king will be cut off and float awayLike a twig on the surface of the water.

wild waves of the sea, flinging up their own shame like foam; wandering stars, for whom the gloom of deep darkness has been reserved forever.
