'Prophets' in the Bible

Of which salvation the prophets have inquired and searched diligently, who prophesied of the grace that should come unto you:

And it was made clear to those prophets that they were God's servants not for themselves but for you, to give you word of the things which have now come to your ears from the preachers of the good news through the Holy Spirit sent down from heaven; things which even angels have a desire to see.
