Verse 19.— And we have a more sure word. The language of the Common Version is in this place ambiguous. The thought is more clearly expressed either in the Revised Version or by Rotherham. The latter has it: "And we have more firm the prophetic word." The idea is that at least some of the brethren addressed have the prophecies that foretold the coming of Messiah, and our testimony makes that prophetic word more firm. It con­firms it. Do well that you take heed. That is, to what the prophecies say on this matter, for those prophecies are as a in a dark place, and as such light-bearers they continued to shine until the perfect day of revelation was ushered in by the arising of the day star; that is, until Christ came.
