This narration is inserted, together with what follows concerning the increase of Abraham’s kindred, for the purpose of showing that the holy man, when he had been brought up again from the abyss of death, was made happy, in more ways than one. For God would so revive him, that he should be like a new man. Moses also records the progeny of Nahor, but for another reason; namely, because Isaac was to take his wife from it. For the mention of women in Scripture is rare; and it is credible that many daughters were born to Nahor, of whom one only, Rebekah, is here introduced. He distinguishes the sons of the concubine from the others; because they occupied a less honorable place. Not that the concubine was regarded as a harlot; but because she was an inferior wife, and not the mistress of the house, who had community of goods with her husband. The fact, however, that it entered into Nahor’s mind to take a second wife, does not render polygamy lawful; it only shows, that from the custom of other men, he supposed that to be lawful for him, which had really sprung from the worst corruption.
