Romans 3:1-4

So what advantage does the Jew have? Or what is the benefit of circumcision? Considerable in every way. First, they were entrusted with the very words of God. What then? If some were unfaithful, will their unfaithfulness nullify God’s faithfulness? Absolutely not! Let God be true, even though everyone is a liar, as it is written: That you may be justified in your words and triumph when you judge.
