What does the Bible say about where Scripture comes from?

The Scriptures are divinely inspired as affirmed in Acts 1:15, where Peter mentions that 'this Scripture must needs have been fulfilled which the Holy Ghost spake.' This highlights that the Scriptures originate from God Himself, and as 2 Timothy 3:16 tells us, 'All Scripture is profitable for doctrine, for reproof, for correction, and for instruction in righteousness.' The Holy Spirit spoke through the prophets, ensuring that the writings were without error, thus providing a trustworthy foundation for the faith.
