κυρόω, κύρω: 1 aorist infinitive κυρῶσαι; perfect passive participle κεκυρωμενος; (κῦρος the head, that which is supreme, power, influence, authority); from Aeschylus and Herodotus down; to make valid; to confirm publicly or solemnly, to ratify: διαθήκην, passive Galatians 3:15; ἀγάπην εἰς τινα, to make a public decision that love be shown to a transgressor by granting him pardon, 2 Corinthians 2:8. (Compare: προκυρόω.)

Topical Lexicon
Core Idea of 2964 in Scripture

The verb translated “ratify,” “confirm,” or “reaffirm” (appearing at Galatians 3:15 and 2 Corinthians 2:8) conveys the formal, authoritative establishment of something so that it may no longer be questioned or altered. In everyday Greek usage of the first century, the term was used in legal contexts for validating contracts, wills, and official decrees. Scripture harnesses that everyday legal force to illuminate covenant theology and practical church life.

Occurrences and Immediate Contexts

Galatians 3:15 – Paul appeals to the permanence of a legally ratified covenant to prove that the promise to Abraham cannot be nullified by the later Mosaic Law: “Even a human covenant, once it is ratified, no one can annul or add to it”.
2 Corinthians 2:8 – After urging the Corinthian believers to forgive and restore a repentant offender, Paul writes, “Therefore I urge you to reaffirm your love for him”.

Though few in number, these verses place the verb at strategic theological and pastoral crossroads: one addresses the unbreakable divine promise, the other the practical healing of church relationships.

Legal and Cultural Background

In Greco-Roman society, a covenant or last will, once sealed and witnessed, carried binding authority. Alterations after ratification were prohibited. Paul leverages that shared legal intuition to argue from the lesser to the greater: if human agreements are irrevocable once confirmed, God’s covenant—sworn by Himself—stands all the more immovable (Hebrews 6:13-18 offers parallel reasoning).

Theological Significance

1. Certainty of God’s Redemptive Plan

Galatians 3:15 undergirds Paul’s entire argument that justification is by faith, rooted in the earlier promise to Abraham and ultimately fulfilled in Christ. The Law, coming 430 years later, did not—and could not—modify the gospel promise. The term therefore becomes a verbal anchor for the doctrine of salvation by grace through faith.

2. Assurance for Believers

Because God’s covenant is “ratified,” the believer’s hope rests on divine initiative rather than human performance. This notion resonates with passages that describe the believer as “sealed” (Ephesians 1:13) and Christ as “the guarantee of a better covenant” (Hebrews 7:22).

3. Integrity of Church Discipline and Restoration

In 2 Corinthians 2:8 the same authoritative tone is redirected toward the community: having exercised corrective discipline, the church must now act with equal decisiveness to confirm its love, lest Satan gain an advantage (2 Corinthians 2:11). The verb elevates that act of restoration to a formal, public commitment, demonstrating that love is as binding as discipline.

Related Old Testament Echoes

• Ratified covenants sealed with blood (Exodus 24:8).
• God “confirms” (Hebrew qûm) His covenant with Noah (Genesis 9:9) and Abraham (Genesis 17:7).

The Greek term in Galatians 3:15 echoes these Hebrew roots, stressing continuity between the Testaments.

Christological Fulfillment

Jesus identifies His blood as “the blood of the covenant” (Matthew 26:28), an unmistakable act of ratification. His resurrection further “declares” (Romans 1:4) the covenant’s validity, making Him both Mediator and surety. Thus the legal imagery embodied in 2964 ultimately points to Christ’s finished work.

Ministerial Application

1. Covenant-Centered Preaching

Galatians 3:15 encourages pastors to proclaim the steadfastness of God’s promise, countering modern doubts about the reliability of Scripture or the exclusivity of the gospel.

2. Balanced Church Discipline

2 Corinthians 2:8 models a two-step process: clear correction followed by equally clear reaffirmation. Churches that practice discipline without restoration risk breeding despair; those that skip discipline risk moral laxity. The verb demands both.

3. Marriage and Vow Renewal

Christian marriage, reflecting Christ’s covenant with the church (Ephesians 5:31-32), can rightly draw upon this concept: vows are not casual but ratified commitments; periodic recommitment ceremonies mirror the “reaffirming love” Paul commands.

4. Sacramental Assurance

Baptism and the Lord’s Supper visibly “confirm” the gospel promise to the congregation, reinforcing faith by sign and seal (Romans 4:11). Each observance proclaims that the covenant, once established, stands unaltered.

Pastoral Reflections

• When doubts assail, remind believers that God’s covenant is already “ratified”; feelings may fluctuate, but the legal standing granted by Christ’s blood does not.
• After discipline, let the congregation’s reaffirmation be as public and wholehearted as the rebuke, fulfilling the apostolic model.
• Teach that Christian liberty rests not in laxity but in the unshakeable security of a confirmed promise; obedience flows from gratitude, not uncertainty.

Doctrinal Summary

Strong’s Greek 2964 serves the New Testament in two complementary ways: guarding the integrity of the gospel promise (Galatians) and guiding the integrity of gospel relationships (2 Corinthians). Both applications rest on a single truth: when God or His people formally establish a matter in accordance with His word, that matter is to be regarded as settled.
