Romans 3:1-4

Then what is the advantage of the Jew? Or what is the benefit of circumcision? Great in every respect. To begin with, the Jews were entrusted with the oracles of God [His very words]. [Ps 147:19] What then? If some did not believe or were unfaithful [to God], their lack of belief will not nullify and make invalid the faithfulness of God and His word, will it? Certainly not! Let God be found true [as He will be], though every person be found a liar, just as it is written [in Scripture], “THAT YOU MAY BE JUSTIFIED IN YOUR WORDS, AND PREVAIL WHEN YOU ARE JUDGED [by sinful men].” [Ps 51:4]
