Psalm 59:5

For he is not a real Jew who is one outwardly, nor is true circumcision something outward and in the flesh.

But it is not as though the word of God had failed. For not all who are descended from Israel are Israel,

For judgment will be without mercy to one who has shown no mercy; mercy triumphs over judgment.
