Friends in this episode we begin to see Israel becoming more of a reality. BUT more importantly we see clearly here that the final decision is made. It is through ISAAC and HIS descendants that God's plan for the world will unfold. And we explain very clearly how this occurs. God has chosen Issac and his descendants and those whom align with Abraham , Isaac and Jacob will be blessed. Abraham's treatment of Abilemech shows this at the end of Chapter 21. I will bless those who bless you and "I will curse those who curse you".
