Thayer's Greek Lexicon
STRONGS NT 3574: νυχθήμερον

νυχθήμερον, νυχθημερου, τό (νύξ and ἡμέρα), a night and a day, the space of twenty-four hours: 2 Corinthians 11:25. (Alex. Aphr.; Geoponica) Cf. Sturz, De dial. Mac. etc., p. 186; (Sophocles Lexicon, under the word; cf. Winer's Grammar, 25).

Topical Lexicon
Concept and Scriptural Context

The word denotes a single, complete cycle of darkness and daylight—a full span of twenty-four hours. Scripture often speaks of “night” and “day” separately to emphasize continual or unbroken activity (for example, Luke 2:37; 1 Thessalonians 3:10). Here, however, the two are fused into a single term, underscoring the unity of the period rather than its parts. This holistic perspective reflects the biblical view that God governs every moment, whether in darkness or in light (Psalm 139:12).

Occurrence in the New Testament

The compound appears once, in 2 Corinthians 11:25: “Three times I was beaten with rods, once I was stoned, three times I was shipwrecked; I spent a night and a day in the open sea”. The rarity of the term draws attention to the specific incident Paul recalls in his catalog of sufferings, highlighting both the severity and the duration of the ordeal.

Old Testament and Intertestamental Background

Although the precise compound is absent from the Hebrew Scriptures, the idea of an inseparable twenty-four-hour cycle runs through the creation narrative: “And there was evening, and there was morning—the first day” (Genesis 1:5). Later Jewish writings used similar compound expressions to describe periods of uninterrupted fasting, prayer, or danger. The usage in 2 Corinthians therefore rests on a conceptual foundation that was already familiar to Paul’s readers.

Paul’s Apostolic Hardship

Paul’s “night and day in the open sea” probably refers to drifting on wreckage before rescue (cf. Acts 27, another maritime crisis occurring later). The vivid recollection functions pastorally and apologetically:
• It authenticates Paul’s apostolic ministry by evidencing costly endurance (2 Corinthians 6:4-5; Galatians 6:17).
• It rebukes opponents who questioned his authority, showing that genuine service embraces suffering rather than prestige.
• It comforts believers experiencing trials, demonstrating that even the harshest elements cannot thwart God’s purpose.

Theological Implications

1. Providence over Time. A continuous twenty-four-hour exposure to the sea proclaims the sustaining hand of God, echoing Psalm 121:4, “He who watches over Israel will neither slumber nor sleep.”
2. Resurrection Hope. The phrase invites comparison with Jonah’s three days and three nights and with Jesus’ prediction of His own burial (Matthew 12:40). Paul’s survival points forward to the greater deliverance secured in Christ’s resurrection, which guarantees safety through every “night and day.”
3. Perseverance of the Saints. The compound accentuates duration; Paul endures the whole cycle without relief. By grace, believers are kept “until the day of Jesus Christ” (Philippians 1:6).

Practical and Pastoral Applications

• Encouragement in Extended Trials. Seasons that feel unending find precedent in Paul’s ordeal; God’s faithfulness spans the entire cycle.
• Vigilance in Ministry. Just as Paul remained afloat until deliverance, churches are called to steadfast watchfulness “night and day” (Acts 20:31) for the flock’s welfare.
• Balanced Rhythm of Life. The unity of night and day reminds disciples to consecrate both rest and labor, embodying Romans 14:8, “Whether we live or die, we belong to the Lord.”

Christological Reflection

Jesus Himself embraced the full scope of human experience—light and darkness, life and death—to redeem every hour. Paul’s peril at sea mirrors, in miniature, the Savior’s descent into the storm for our salvation (Mark 4:35-41). Just as Christ’s command calmed the waves, His sovereign care sustained His apostle through the twenty-four-hour trial.

Doctrinal Connections

• Sovereignty: God ordains the extent and outcome of each trial (Job 1:12).
• Suffering and Glory: Momentary affliction works “an eternal weight of glory” (2 Corinthians 4:17).
• Mission: Hardship validates the gospel messenger and advances the message (Philippians 1:12-14).

Worship and Spiritual Formation

Meditating on the term invites believers to dedicate every portion of the day to praise and trust. Practices might include:

– Morning thanksgiving for sustaining grace.

– Evening examination, recalling God’s presence through the day’s events.

– Intercessory prayer that spans “night and day,” reinforcing unceasing dependence (1 Timothy 5:5).

Summary

In its lone New Testament appearance, the compound for “night-and-day span” crystallizes Paul’s testimony of endurance and God’s overarching care. The term gathers together themes of providence, perseverance, and gospel authenticity, encouraging believers to entrust every hour—whether marked by darkness or light—to the Lord who reigns over the full cycle of time.
