Waves are swimming motions of the water, caused by the action of the wind. Their height and velocity deepen on the forces of the wind, and depth of the basin in which they occur. The stronger the wind, and the deeper the ocean, the higher the waves and the greater their velocity.

"But lighting upon a place where two seas met, they ran the vessel aground; and the foreship struck and remained unmoveable, but the stern began to break up by the violence of the waves. And the soldiers' counsel was to kill the prisoners, lest any of them should swim out, and escape. But the centurion, desiring to save Paul, stayed them from their purpose; and commanded that they who could swim should cast themselves overboard, and get first to the land; and the rest, some on planks, and some on other things from the ship. And so it came to pass, that they all escaped safe to the land." Acts 27:41-44 ASV <p>Illustration of Paul's ship wrecking in the waves on the coast of Malta. The ship can be seen sinking in the background as Paul and several soldiers swim in the violent waves. One soldier clings to a splinter of wood.
