Topical Lexicon
Meaning and Nuance

Strong’s Greek 1603 (ἐκπληρόω) expresses the idea of bringing a promise or prophecy to total completion, leaving nothing outstanding. The prefixed preposition ἐκ strengthens the base verb, underscoring decisive, exhaustive fulfillment.

Biblical Usage Context

The sole New Testament occurrence stands in Paul’s synagogue sermon at Pisidian Antioch (Acts 13:33). Announcing the resurrection of Jesus as the climactic confirmation of messianic prophecy, Paul proclaims: “God has fulfilled for us, their children, by raising up Jesus, as it is written in the second Psalm: ‘You are My Son; today I have become Your Father.’”. Here, ἐκπεπλήρωκεν highlights that God’s redemptive plan, foretold in Scripture, has reached its intended conclusion in the risen Christ.

Old Testament Background

1. Psalm 2:7 (quoted in Acts 13:33) declares the enthronement of the Son.
2. 2 Samuel 7:12-14 promises David an everlasting dynasty.
3. Isaiah 55:3-4 offers “the sure mercies of David.”

By using ἐκπληρόω, Paul links these covenantal assurances to an accomplished reality. The verb stresses that the events surrounding Jesus do not merely correspond to prophetic words; they exhaustively complete them.

Divine Faithfulness Revealed in the Resurrection

The perfect tense—“has fulfilled”—anchors fulfillment in a past act with continuing results. The resurrection, therefore, is not an isolated wonder but the fixed guarantee that every promise bound to the Davidic Messiah is already active and irrevocable (Romans 1:4; 2 Timothy 2:8).

Authority of Scripture Affirmed

Paul’s argument assumes Scripture’s inerrancy: if God stated it, God completed it. The intensifying verb form guards against any notion of partial or incremental fulfillment. Every detail is shown to be trustworthy, reinforcing passages such as Joshua 23:14, “Not one word has failed,” and Matthew 5:18, “Until heaven and earth pass away, not the smallest letter… will by any means disappear.”

Christological Significance

1. Sonship: Psalm 2 finds its definitive embodiment in Jesus’ resurrection, declaring Him the eternally begotten Son (Hebrews 1:5).
2. Kingship: The completed promise establishes Jesus as the reigning King, seated at the right hand of God (Psalm 110:1; Acts 2:33-36).
3. Covenant Mediation: With the promises fully met, Christ mediates the “better covenant” (Hebrews 8:6), guaranteeing forgiveness and life to all who believe.

Implications for Preaching and Discipleship

• Assurance: Believers rest in a finished work; salvation is not contingent on human achievement (John 19:30).
• Evangelism: The verb undergirds gospel proclamation—God keeps His word, therefore the call to repentance stands on unshakable ground (Acts 17:30-31).
• Hope: Future promises (1 Thessalonians 4:16-17; Revelation 21:1-4) are as certain as those already fulfilled.

Related Themes and Terms

• Fulfillment: πληρόω (Strong’s 4137) – ordinary “to fulfill.”
• Promise: ἐπαγγελία (Strong’s 1860) – “promise.”
• Covenant: διαθήκη (Strong’s 1242) – “covenant.”
