Have you noticed a recurring sub plot in the story of God choosing the younger, weaker and more unlikely over the stronger and culturally sanctioned older child. God chooses Abel (not Cain), Isaac (not Ishmael), Jacob (not Esau) and Judah (not Reuben). Violence and rivalry often occurs amongst siblings who belong to the same family. Likewise amongst the women, the wives who are loved are barren for a long while before they received their promised child. (Sarah, Rebekah, Rachel) What do these chapters tell you about God?
