(2 Peter 1:21 NIV) For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit.

(Jude 1:3 NIV) Dear friends, although I was very eager to write to you about the salvation we share, I felt I had to write and urge you to contend for the faith that was once for all entrusted to the saints.

The first verse is a more direct example of how the Holy Spirit inspired scripture. The second one is a less known example.
