Abraham's Family is a Changin'

Abraham, after much suspense to have an heir, is now forced to envision the how this tribe will continue after he is gone.

Another woman is added to the family in chapter 24 when Isaac gets married through a very detailed, elongated proposal that must be with Abraham's family back in Haran. Through all of this, the covenant continues and we get a very specific ideology as to who Israel will be and how they ought to function as Isaac is formally shown to be the primary heir in chapter 25 and the lineage begins to unfold toward Jacob and Esau.
