What does Hebrews 1:9 mean?
This verse continues a quotation of Psalm 45:6–7, which is mentioned to show that the Messiah is invested with an everlasting throne and godly authority. Hebrews 1:7 gave a contrasting reference to angels as servants, with shifting characteristics. This Old Testament reference, begun in verse 8, is meant to prove that Jesus Christ is clearly not an angel or some other created being.Psalm 45:7, quoted here in Hebrews 1:9, again emphasizes the moral status of this king. This pair of verses (with Psalm 45:6, quoted in Hebrews 1:8) also frames a prophecy about the nature of David's lineage. The Messiah is the ultimate fulfillment of this promise: that David's line would never end and his throne would be established forever. As is often the case with the Old Testament, there are multiple layers of meaning involved. While the Psalm most directly applies to the wedding of an earthly king, Hebrews shows how it also gives application for understanding the Promised One, Jesus.
