Romans 1:2. Which he promised beforehand. The parenthesis is unnecessary, for the whole passage is closely connected. It must be God's gospel, for He had already promised it, and this thought would have force with the Gentile Christians as well as the Jews.

The Greek-speaking Jews probably used the phrase as a proper noun, as in the case of the word ‘law.' The omission of the article, in such usage, does not imply any indefinite or general meaning. ‘The divine promises of the gospel, given through the prophets of God, are found in such books as, being God's records for His revelations, are holy writing'(Meyer).

The gospel, Paul implies, though new, is yet old.
