Romans 3:19

Romans 3:19. Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.

The law was given to the Jews, and the descriptions which it gives must be descriptions of the Jews "Therefore," says Paul, "as Gentile mouths have been already stopped by the descriptions of their vices, you also, the favored people of God, have your mouths stopped by the descriptions of yourselves taken from your own prophets."
