Psalm 59:5

For the real Jew is not the man who is one outwardly, and the real circumcision is not outward in the flesh;

It is not, however, as though God's word had failed! For they are not all Israel who have sprung from Israel;

For judgment is without mercy to the man who has showed no mercy. but mercy glories in the face of judgment.
