'Descendants' in the Bible

He has no children or descendants within his own people; and no survivors where he once lived.

If he has many children, their destiny is to die by the sword, and his descendants won't have enough food.

But then Barachel's son Elihu from Buz, one of Ram's descendants, got really angry. He was furious with Job because he had been declaring himself righteous instead of vindicating God.
