Thou Art a Priest Forever after the Order of Melchizedek
The divine oath appoints the royal figure as a priest forever after the order of Melchizedek. Hebrews repeatedly quotes and expounds this verse in relation to Jesus, especially in chapters 5–7, arguing for a priesthood grounded in divine oath rather than Levitical genealogy. This is explicit inspired Christological interpretation and a major King-Priest thread.
