1 Chronicles 1:38

Ver. 38-42. And the sons of Seir
This man and his posterity were not of the race of Esau, but are mentioned because they were a family into which Esau, and a son of his, married, and whose possessions he and his obtained. The account from hence, to the end of ( 1 Chronicles 1:42 ) is the same with ( Genesis 36:20-28 ) , with some little variation of names.
