“Jacob I loved, but Esau I hated”: Paul quotes Malachi 1:2–3. In that passage, Jacob, whose other name is Israel (Genesis 32:28). , represents the nation of Israel. Esau represents the nation of Edom.
Here in Romans, Paul speaks of Jacob and Esau as individuals. In the Bible, the word love can express choice or acceptance. In the same way, the word hate can express rejection rather than personal anger. Paul uses the story of Jacob and Esau to show that God, who rules over all things, chooses his people according to his own purpose.
