Topical Lexicon
Summary of Biblical Usage

Strong’s Greek 1604 occurs once in the New Testament, Acts 21:26, where it describes the completion of a set number of days connected with a purification rite in the Jerusalem temple. The noun conveys the idea of bringing a prescribed period or obligation to its full and rightful end—nothing lacking, nothing truncated.

Narrative Setting in Acts 21

Paul, having arrived in Jerusalem, willingly participates in a temple ritual to demonstrate his respect for the Mosaic Law and to quell rumors that he teaches Jews to forsake their customs. Accompanied by four men under a vow, he “took the men, and the next day he purified himself along with them and went into the temple, giving notice of the completion of the days of purification” (Acts 21:26). The focus of the verse is a public declaration before God and witnesses that the period appointed by the Law had reached its ordained finish.

Historical Backdrop

1. Temple Vows and Purification
Numbers 6:1-21 outlines the Nazirite vow, which often included shaving the head and bringing offerings after “the days are fulfilled.”
• Extra-biblical sources (Josephus, Antiquities 19.294) confirm that first-century Jews marked the end of such vows with sacrifices and communal observance in the temple courts.
• Paul’s act aligns with the Jewish expectation that vows be fulfilled publicly and punctually.

2. Early Church Dynamics
• The Jerusalem church contained thousands of Jewish believers “zealous for the Law” (Acts 21:20).
• By joining the vow, Paul models cultural sensitivity (cf. 1 Corinthians 9:20) without compromising gospel truth.
• The single use of ἐκπλήρωσις highlights the tension—and resolution—between continuity with Old Testament practice and freedom in Christ.

Theological Significance

1. Completion as Integrity

Scripture consistently links fulfillment with covenant faithfulness. Whether finishing a vow, a season, or a prophecy, God’s people are exhorted to bring commitments to the point of ἐκπλήρωσις (Ecclesiastes 5:4-5; Deuteronomy 23:21).

2. Foreshadowing the Greater Fulfillment in Christ
• Jesus came “not to abolish the Law or the Prophets; I have not come to abolish them, but to fulfill them” (Matthew 5:17, verb πληρόω).
• Paul’s action underscores that earthly rituals, though temporary, point to the ultimate completion secured by Christ’s once-for-all sacrifice (Hebrews 10:12-14).

3. Witness Before Jew and Gentile

Fulfilling the vow silenced critics and preserved the unity of the church. ἐκπλήρωσις therefore functions missiologically, displaying tangible obedience that clears the way for gospel proclamation (Acts 21:27-28 shows the result when misunderstandings still arose).

Connections with Related Biblical Terms

• πληρόω (to fill, fulfill): Used of prophetic completion (Matthew 1:22), moral obedience (Romans 13:8), and eschatological consummation (Revelation 15:1).
• τέλειος (perfect, complete): Describes maturity brought to fruition in believers (James 1:4).

Together these words frame a biblical theology of fulfillment—from ceremonial law to personal sanctification to cosmic restoration.

Practical Ministry Applications

1. Faithful Stewardship of Commitments

Believers are encouraged to finish what they begin, whether in vows, projects, or ministries (2 Corinthians 8:11).

2. Cultural Sensitivity Without Compromise

Adapting to local customs, as Paul did, can remove needless offense and advance the gospel (Galatians 5:6).

3. Corporate Accountability

The temple setting reminds modern congregations that completion often requires community support and public testimony (Hebrews 10:24-25).

4. Hope of Ultimate Completion

The momentary ἐκπλήρωσις in Acts 21 anticipates the day when “He who began a good work in you will bring it to completion” (Philippians 1:6), strengthening perseverance.

Conclusion

Strong’s 1604 encapsulates the biblical call to bring every God-given task, season, and promise to its appointed end. In Acts 21 it reveals Paul’s integrity, protects church unity, and foreshadows the total fulfillment accomplished in Christ and awaited in His return.
