This chapter examines passages in Hebrews where the Spirit is portrayed as the speaker of Scripture quotations (Heb 3:7–4:11; 10:11–18). Due to previous skepticism about the Spirit’s role in Hebrews, this chapter also argues that the Spirit is a speaker in the same way as the Father and Son and that the author uses his speech to develop a thoroughly distinct divine character. In Hebrews 3-4, potentially the longest pneumatological discourse in the NT, the Spirit encourages the addressees to avoid the error of the wilderness generation and press on towards rest. In Hebrews 10, the Spirit “testifies” to the benefits of the new covenant - especially forgiveness. In contrast to the Father and Son, the Spirit’s conversation partner is “us.”
