Romans 3:6

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.
