Scholars often divide the Epistle to the Hebrews into two parts. The first, chapters 1-10, teach on the supremacy of Messiah (chapters 1-8) and the new covenant cut in Messiah’s blood (chapters 8-10). The second part, chapters 10-13, is exhortation on how we are to respond to the truths found in the first part.
Hebrews: ὑπέρ | huper
