Romans 3:1-4 KJV
What advantage then hath the Jew? or what profit is there of circumcision? Much every way: chiefly, because that unto them were committed the oracles of God. For what if some did not believe? shall their unbelief make the faith of God without effect? God forbid: yea, let God be true, but every man a liar; as it is written,
That thou mightest be justified in thy sayings,
And mightest overcome when thou art judged.
