Despising the Birthright – Malachi 2:10-12

He shows that the Jews had descended in no common or ordinary way from their holy father Abraham, but that God was the maker of his race, that he created them. Did not he also create the rest of the world? Not in the same manner; for this creation ought to be confined especially to the Church. God has created the whole human race; but he created also the race of Abraham: and hence the Church is often called in Isaiah the work and the formation of God, (Isaiah 66:21,) and Paul also adopts the same mode of speaking, (Ephesians 2:10.) Our Prophet then does not mean that the Jews had been created by God when born into this world, but that they had become his holy and peculiar people. As then God had thus created the Jews, and had given to them one father, that being mindful of their origin they might remain united in true religion, the Prophet here reprobates their sottishness in casting away from themselves this invaluable favor of God. – John Calvin
