This verse in the King James

King James wording
(For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou art a priest for ever after the order of Melchisedec:)

This priesthood rests on a divine oath that will not be taken back.

This verse presents a priesthood that stands now because God’s appointment is backed by an oath. Its permanence does not depend on the succession of priests made without one; the appointed priest remains through the age, and God does not withdraw the word.

WHAT THIS UNDOES

The belief that every priestly office must end with its human holder is undone here: this appointment rests on a sworn word that is not withdrawn.

μεταμεληθήσεται

metamelēthēsetai

GROWS FROM

μεταμελ-

metamel-

to regret or change one’s mind

“take it back” in this verse is metamelēthēsetai. The Greek word means changing one’s mind or regretting a decision. The verse says this appointment is not subject to that reversal.

ALSO GROWS

metamelomai: regret; change one’s mind

μεταμέλομαι

This is the verb family behind the word used here, making the sense of reversal explicit.

ametamelētos: without regret; irrevocable

ἀμεταμέλητος

Romans 11:29 uses this related form for God’s gifts and calling, linking them with the unwithdrawn appointment here.

ὁρκωμοσίας

horkōmosias

GROWS FROM

ὅρκος

horkos

an oath; a solemn sworn pledge

The verse pairs the oath with the Lord’s act of swearing, making the spoken commitment the stated ground of the appointment. The contrast is clear: those priests are made without an oath, while this one is appointed with one.

ALSO GROWS

horkos: oath

ὅρκος

This is the core oath-word contained in the term for oath-taking used in the surrounding passage.

exorkizō: adjure; bind by an oath

ἐξορκίζω

This related verb shows the oath-family’s force as a solemn appeal that binds the speaker to a declaration.

αἰῶνα

aiōna

GROWS FROM

αἰών

aiōn

an age; a span of time

“for the ages” in this verse is aiōna. The phrase rendered for ever contains ⁨αἰῶνα⁩ (aiōna), the Greek word for age. The age-language gives the sworn appointment a duration that stretches forward through the age.

ALSO GROWS

aiōn: age; era; span of time

αἰών

This is the noun used in the phrase describing how long the priesthood stands.

aiōnios: of an age; age-lasting

αἰώνιος

This related adjective carries the same age-language into descriptions of what endures.

God’s commitments are portrayed as sworn or steadfast speech whose fulfillment is not subject to reversal.

And he said, "By myself I have sworn, declares the LORD, because you have done this thing, and have not held back your son, your only son.
Genesis 22:16 · SDVGod grounds the promise in an oath sworn by himself, marking the blessing as a stated divine commitment.
God is not a man, that he should lie, nor a son of man, that he should relent. Has he said, and will he not do it? Has he spoken, and will he not make it stand?
Numbers 23:19 · SDVGod’s refusal to lie or change his mind is joined to the certainty that what he speaks will be done.
For the favors and the calling of God are not taken back.
Romans 11:29 · SDVGod’s gifts and calling are described as free from regret or reversal, echoing the word-family used for the priestly appointment.
For the favors and the calling of God are not taken back.
Romans 11:29 · SDV

Hebrews uses ⁨μεταμεληθήσεται⁩ (metamelēthēsetai, “will change his mind”), while Romans uses ⁨ἀμεταμέλητα⁩ (ametamelēta, “without regret”); both belong to the same Greek word-family. Romans attaches that same quality to God’s gifts and calling, placing the enduring priestly appointment within a wider pattern of commitments God does not withdraw.
