What does Hebrews 7:16 mean?
This passage in Hebrews explains how the priesthood of Jesus Christ is like that of Melchizedek, which makes it superior to the Levitical priesthood of the Old Testament. Levitical priests gained their position on the basis of their ancestry—only those from the tribe of Levi could serve in that role (Deuteronomy 18:1; Numbers 3:5–10). Melchizedek, on the other hand, was a "priest of God Most High" long before the birth of Levi or Aaron (Genesis 14:18). Abraham even paid tithes to this man (Hebrews 7:6–7), showing reverence for his position. The writer of Hebrews compares this to statements such as Psalm 110:4, where God promises to establish the priesthood of Melchizedek forever, and prior statements that the Messiah will be both priest and king (Hebrews 1:8–9; 5:5–6).Jesus, then, does not obtain His priesthood in the way that a Levitical priest would: through human ancestry. Instead, His position is secured through His "indestructible" life. This is from the Greek word akatalytou, literally meaning "indissoluble," or "unending." A point made earlier was that Melchizedek, metaphorically speaking, is presented with an "endless" life, symbolized by his lack of recorded genealogy (Hebrews 7:3, 8). This, again, is meant to prove that Jesus Christ and His priesthood are the true means of salvation for man, rather than the imperfect system of the Old Testament priesthood.
