For in order that the purpose of God, working through selection, might not fail-a selection depending, not on obedience, but on his Call-Rebecca was told, before her children were born and before they had done anything either right or wrong,

For even before the twins were born, and therefore had not done anything good or bad, Rebecca was told [Gen. 25:23], "The older one [i.e., Esau] will serve the younger one [i.e., Jacob]." This was so that God's purpose of choosing and calling [whomever He wanted to] might prevail, instead of [it depending on] what a person did.
