“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.”
King James Version (KJV)
3:19 Whatsoever the law - The Old Testament. Saith, it saith to them that are under the law - That is, to those who own its authority; to the Jews, and not the gentiles. St. Paul quoted no scripture against them, but pleaded with them only from the light of nature. Every mouth - Full of bitterness, #Rom 3:14|, and yet of boasting, #Rom 3:27|. May become guilty - May be fully convicted, and apparently liable to most just condemnation. These things were written of old, and were quoted by St. Paul, not to make men criminal, but to prove them so.
Ro 3:19 Whatever things soever the law saith, etc. The law of Moses was written for the Jews especially, and whatsoever it saith, it saith to those under it, to the Jews; just as the United States law is addressed to the people of the United States. That every mouth may be stopped. It has just been seen that even the mouth of the Jew is stopped, since "none are righteous, no, not one" (Ro 3:10 Ps 14:3); hence all the world, Jew as well as Gentile, are "guilty before God".
