If I had the ability, I would. Unfortunately, I'm just not that learned. I can tell you it is learned out that Laban came back as Bilam, the prophet who was supposed to curse Israel but wound up blessing them, and later as Nabal (I think that's the name), the husband of a woman King David later married. As Nabal, he dies a painful natural death, and the rabbis learn out from this that his death is an atonement for his sins. This final event happens in the book of Samuel.
