And Thou, O God, from afar perceivedst me stumbling in that slippery course, and amid much smoke sending out some sparks of faithfulness, which I showed in that my guidance of such as loved vanity, and sought after leasing, myself their companion. In those years I had one, -not in that which is called lawful marriage, but whom I had found out in a wayward passion, void of understanding; yet but one, remaining faithful even to her; in whom I in my own case experienced what difference there is betwixt the self-restraint of the marriage-covenant, for the sake of issue, and the bargain of a lustful love, where children are born against their parents' will, although, once born, they constrain love.
