This is another one of those insomnia-curing chapters. Esau took all of his family and cattle and whatnot and left the land where Jacob was staying, because the two of them together had too many cows for the land to support.

Also Esau begat Eliphaz, who begat Teman, Omar, Zepho, Gatam, and Kenaz. Esau also begat some other sons, and they begat a whole bunch of other people, all of whose names look like what you would get if a herd of cats walked over your keyboard. For 43 verses, people have kids and those kids have other kids, and the translator passes out from sheer boredom and the chapter ends.
