'Revelation' in the Bible

For I did not get it from man, and I was not given teaching in it, but it came to me through revelation of Jesus Christ.

To give the revelation of his Son in me, so that I might give the news of him to the Gentiles; then I did not take the opinion of flesh and blood,

And I went up by revelation; and I put before them the good news which I was preaching among the Gentiles, but privately before those who were of good name, so that the work which I was or had been doing might not be without effect.

But before faith came, we were kept in prison under the law, waiting for the revelation of the faith which was to come.
