2 Samuel 13:37-39

But Absalom fled, and went to Talmai, the son of Ammihud, king of Geshur. And David mourned for his son every day. So Absalom fled, and went to Geshur, and was there three years. And the soul of king David longed to go forth unto Absalom: for he was comforted concerning Amnon, seeing he was dead.
