Another anticipation of an objection, to this purpose: All these testimonies (might the Jews say) do not concern us, they concern the impure and Gentile world only, unless possibly some profane wretches amongst ourselves also. But to this the apostle says; We know (which some think hath the force of an asseveration) that whatsoever the law of God, more especially the Mosaical law, or more generally all that is contained in the Scripture, saith of the wickedness and defection of mankind, it saith to the Jews more particularly, to whom the law was given, and who are under the conduct of it; much the same with that phrase, Romans 2:12: see Romans 6:15 1 Corinthians 9:20. That every mouth may be stopped; i.e. hindered from boasting, to which the Jews were so prone; or rather, that conscience might so press them, that they should silently, or as it were speechless, expect their own damnation. without being able to frame any excuse: see Psalms 63:11 Ezekiel 16:63 Matthew 22:12. And all the world may become guilty before God; that Jews and Gentiles and all mankind, as depraved, might be obnoxious to the judgment and condemnation of God: see Romans 3:9, and 1 Thessalonians 3:18.
