In Hebrews 3:7, the author writes, “Therefore, as the Holy Spirit says,” and then he quotes from Psalm 95. Remarkably, this word of Scripture, written a thousand years prior, can be introduced with the words “the Holy Spirit says.” Scripture is not a dead letter. God not only has spoken in the Scriptures, but he continues to speak through the Scriptures. That’s the assumption behind Hebrews 3:7.
