As in Job 38:8-11, so, probably, here also there is something of the wonder of one to whom, as dwelling in an inland village, the billows breaking on the shore was an unfamiliar sight. Here was the token that even the forces which seem wildest and least restrained are subject to an overruling law. Even the sand which seems so shifting keeps in the surging waters.
