Did the Old Testament Prophets Know What They Were Saying?

"When reading Scripture, the tendency of many Christians is to think in terms of what this verse means to me. What the Bible means to a given individual, however, is completely irrelevant, for the true meaning of Scripture is found not in the subjective impression of the contemporary reader but rather in the specific intention of the original author. For this reason, we often speak of “authorial intent” as the goal of Bible interpretation.

But this only raises a further question: exactly whose intent are we seeking to ascertain? The intent of the human author or the intent of the divine author? Or is it possible that there is actually no tangible difference between the two? Herein lies one of the key issues in the field of hermeneutics today—the question of whether the human intention and divine intention of Scripture are one and the same.

A Closer Look at a Difficult Passage
Some interpreters point to 1 Peter 1:10 as evidence of a sharp distinction between of the human and divine intention of OT prophecy. In this passage, the apostle Peter writes:  (10) As to this salvation, the prophets who prophesied of the grace that would come to you made careful searches and inquiries, (11) seeking to know what person or time the Spirit of Christ within them was indicating as He predicted the sufferings of Christ and the glories to follow. (12) It was revealed to them that they were not serving themselves, but you, in these things which now have been announced to you through those who preached the gospel to you by the Holy Spirit sent from heaven—things into which angels long to look.

According to this view, 1 Peter 1:10-12 teaches that the OT prophets did not understand the meaning of their own prophecies. For this reason, it is said, the human and divine intent of Scripture cannot be regarded as one and the same.
