I want to thank Jon Rinker for sending me a copy of his dissertation:
Jonathan A. Rinker. "Creation, Consummation, Perseverance and the Use of Psalm 102:25–27 in Hebrews 1:10–12." Ph.D. diss., Baptist Bible Seminary, 2017.
Jon is the Vice President for Development and Chair of Bible/Theology Deptment at Appalachian Bible College.
With his permission, I print the abstract:
"The heavy use of Old Testament quotation in Hebrews is spawned in Heb 1 as the author describes the glory of God’s revelation in his Son. This dissertation considers how the author of Hebrews uses one of those quotations, LXX Ps 101:26–28 in Hebrews 1:10–12, in order to show the significance of this quotation for his exposition and exhortation.
Chapter two explores the structure and message of Ps 102, which weaves lament for suffering and the unrealized Davidic promises, along with a hymn of praise that envisions these promises fulfilled in Zion’s restoration. Chapter three examines Ps 102:25–27 in its OT context. On the surface, this prayer acknowledges Yahweh as the eternal and changeless Creator. However, in light of the psalmist’s desperate suffering, his prayer demonstrates a persevering trust in Yahweh’s word, although still unfulfilled.
Chapter four turns to examine the literary and historical contexts of Hebrews, noting the serious threats to the faith of the recipients, and the author’s expository and hortatory aims in order to warn and comfort his congregation. Chapter five closely examines Heb 1:10–12 in the argument of 1:1–14 and its distant parallel in 12:25–29.
Chapter six examines the text form of the citation, noting its origin in the LXX, and the questions this raises about the author’s hermeneutical warrant. Next, this chapter provides a detailed exegesis of 1:10–12 in order to discern its meaning and significance in context. The conclusion here is that the psalm citation at Heb 1:10–12 makes a strong contribution to the author’s portrayal that Jesus has been appointed as the Davidic heir who rules in the world to come, fulfilling the promises for Israel’s restoration in Zion.
Chapter 7 broadens the scope to consider the quotation’s contribution of the argument of Hebrews. The conclusion here is that Heb 1:10–12 is foundational for both the author’s exposition on the Son, and his exhortation to the sons. Finally, chapter 8 summarizes this study, notes some of its unique contributions, and suggests opportunities for further study."
Anyone who wants a copy of the dissertation, let me know. He has granted me permission to distribute the dissertation.
