Concerning this salvation, the prophets sought and searched diligently, who prophesied of the grace that would come to you,
And searched diligently - ἐξερευνάω exereunaō. Compare Daniel 9:2-3. The word used here means to search out, to trace out, to explore. It is not elsewhere used in the New Testament, though one of the words from which this is compounded (ἐρευνάω ereunaō) occurs. See John 5:39, (Notes) John 7:52; Romans 8:27; 1 Corinthians 2:10; Revelation 2:23. The idea is, that they perceived that in their communications there were some great and glorious truths which they did not fully comprehend, and that they diligently employed their natural faculties to understand that which they were appointed to impart to succeeding generations. They thus became students and interpreters for themselves of their own predictions. They were not only prophets, but men. They had souls to be saved in the same way as others. They had hearts to be sanctified by the truth; and it was needful, in order to this, that truth should be applied to their own hearts in the same way as to others. The mere fact that they were the channels or organs for imparting truth to others would not save them, any more than the fact that a man now preaches truth to others will save himself, or than the fact that a sutler delivers bread to an army will nourish and support his own body.
