Being a father, having an heir, seem to add an extra dimension to David. He had always been of vivid, animating presence in any room he entered. But now he would come from visiting the boy crackling with even greater energy and force. He had been engaged listener, ready to learn what any man might have to offer in discussion, but now there was an additional depth to his questions, a more far-reaching vision behind his decisions. He thought now beyond the span of years, and into a future that glistened ahead into centuries. It's one thing, I suppose, to have a prophet tell you that you will found a dynasty. Now, it seemed, he allowed himself to truly believe it.
