STRONGS NT 1417: δύο

Topical Lexicon
Literal Enumeration in Daily Life

The term is regularly employed as an ordinary numeral. It tallies fishing boats (Luke 5:2), sparrows (Matthew 10:29), denarii (Luke 10:35), copper coins (Mark 12:42), fish and loaves (Matthew 14:17; John 6:9), stone water jars (John 2:6) and prisoners’ chains (Acts 12:6). Its frequency in mundane contexts testifies to the Gospel writers’ historical precision, while preparing the reader for richer theological layers bound to the number.

Witness and Legal Confirmation

“Every matter must be established by the testimony of two or three witnesses.” (Matthew 18:16; quotation of Deuteronomy 19:15). The pattern stands behind:
• Christ’s validation of the Baptist’s testimony plus His own works (John 5:31-36).
• The Temple police’s requirement of corroboration against Jesus (Matthew 26:60).
• Paul’s insistence on multiple witnesses for church discipline (1 Timothy 5:19) and for prophetic utterance (1 Corinthians 14:29).

The repetition underscores God’s justice: truth is verified, not assumed.

Companionship in Mission

Jesus “sent them two by two ahead of Him.” (Luke 10:1). The Twelve are likewise paired (Mark 6:7). Advantages emerge: encouragement, accountability, shared gifts, and an instant legal quorum when testifying. Acts continues the pattern: Peter and John (Acts 3:1), Paul and Silas (Acts 15:40), Barnabas and Mark (Acts 15:39). Authentic ministry flourishes in godly partnership.

Marriage and Covenant Unity

“ ‘The two will become one flesh.’ ” (Mark 10:8 citing Genesis 2:24). Marriage illustrates covenant faithfulness and prefigures Christ and the Church (Ephesians 5:31-32). The union of two into one safeguards the doctrine that God’s design for family is male and female fused in lifelong fidelity.

Jew and Gentile Reconciled

“He made the two one and has torn down the dividing wall of hostility.” (Ephesians 2:14-15). Through the cross, previously estranged peoples form a single new humanity. The numeral here conveys the miracle of unity without erasing personal distinction—an evangelistic apologetic to a fragmented world.

Service and Allegiance

“No one can serve two masters.” (Matthew 6:24; Luke 16:13). The saying confronts divided loyalty, pressing hearers toward wholehearted devotion to God over wealth. The pairing exposes the impossibility of spiritual neutrality.

Contrast, Choice, and Division

Parables pivot on two alternatives:
• Two sons—one polite yet disobedient, one defiant yet repentant (Matthew 21:28-32).
• Two builders—one on rock, one on sand (Matthew 7:24-27).
• Two men in a field, two women grinding; one taken, the other left (Matthew 24:40-41).

Scripture frames decisive moments as binary, urging readers toward wise and faithful responses.

Redemption at the Cross

“Two robbers were crucified with Him, one on His right and one on His left.” (Matthew 27:38). The scene models salvation and condemnation side-by-side: one criminal mocks, the other believes (Luke 23:39-43). Humanity’s ultimate choice is embodied in the pair.

Revelation’s End-Time Witness

“I will empower My two witnesses, and they will prophesy for 1,260 days.” (Revelation 11:3). The number grounds their testimony in Mosaic legality while recalling Elijah and Moses, representatives of prophetic and legal revelation. Their career confirms God’s unbroken witness even during tribulation.

Apocalyptic Pairs and Antitheses

Revelation multiplies dualities: two woes remaining (9:12), a beast with two horns (13:11), the lake of fire seizing the beast and false prophet (19:20). Such couplings dramatize the final clash between truth and deceit.

Representative Gospel Snapshots

• Two demoniacs liberated in Gadara (Matthew 8:28).
• Two blind men healed near Jericho (Matthew 20:30).
• Two disciples on the road to Emmaus (Luke 24:13).
• Two angels at the empty tomb (John 20:12; Acts 1:10).

Each episode reinforces that testimony is sufficient and complete.

Pastoral Caution and Comfort

Hebrews anchors hope in “two unchangeable things” (Hebrews 6:18)—God’s promise and oath—so that believers “may have strong encouragement.” Assurance rests not on human strength but on the immutable character of the Lord.

Conclusion

Throughout the New Testament the numeral 1417 transcends arithmetic. It signals verified truth, covenant unity, decisive choice, missionary practice, and eschatological certainty. Every occurrence, whether counting coins or heralding cosmic judgment, harmonizes with the biblical theme that in the mouth of two witnesses every word stands confirmed—and God has left Himself not without witness.
