13.17.20   Who gathered the embittered together into one society? For they have all one end, a temporal and earthly felicity, for attaining whereof they do all things, though they waver up and down with an innumerable variety of cares. Who, Lord, but Thou, saidst, Let the waters be gathered together into one place, and let the dry land appear, which thirsteth after Thee? For the sea also is Thine, and Thou hast made it, and Thy hands prepared the dry land. Nor is the bitterness of men's wills, but the gathering together of the waters, called sea; for Thou restrainest the wicked desires of men's souls, and settest them their bounds, how far they may be allowed to pass, that their waves may break one against another: and thus makest Thou it a sea, by the order of Thy dominion over all things.
