HELPS Word-studies

1798 enýpnion (from 1722 /en, "in the sphere of" and 5258 /hýpnos, "sleep") – properly, in sleep; a dream while asleep (used only in Ac 2:17).

1798 /enýpnion ("a dream") is an ideal time for the Lord to communicate in a way we easily block in the busyness of life. The Christian therefore should go to sleep prayerfully, open to communing with God all through the night to receive strength and illumination from Him.

Topical Lexicon
Overview

Strong’s Greek 1798, ἐνύπνιον, points to a divinely-given dream. It occurs once in the Greek New Testament, in Acts 2:17, where Peter quotes Joel’s prophecy concerning the outpouring of the Spirit. Although rare in the New Testament, the term gathers up a rich Old Testament theology of nocturnal revelation and situates it within the age of the Gospel.

Old Testament Foundations of Revelatory Dreams

Genesis 20:3; Genesis 31:11; Genesis 37:5-11 – God communicates guidance and destiny through dreams to patriarchs and prophets.
Numbers 12:6 – “Hear My words: If there is a prophet among you, I, the LORD, will make Myself known to him in a vision; I will speak to him in a dream.” Dreams are thus placed alongside visions as a legitimate prophetic medium.
1 Kings 3:5 – Solomon receives wisdom in a dream at Gibeon.
Daniel 2 and Daniel 4 – Nations and kings are warned and instructed through prophetic dreams.

These passages teach that the Sovereign LORD chooses the timing, recipients, and content of dreams, and that such revelations never stand in isolation from His covenant purposes.

Acts 2:17: Fulfilment in the Last Days

Peter’s Pentecost sermon identifies the descent of the Spirit as the turning point anticipated by Joel. Quoting from the Septuagint he declares:

“‘In the last days, God says, I will pour out My Spirit on all people; your sons and daughters will prophesy, your young men will see visions, your old men will dream dreams.’” (Acts 2:17)

Key observations:

1. The plural “dream dreams” broadens the experience from singular prophets to multitudes (“all people”).
2. Generational breadth—“old men”—illustrates that no stage of life is excluded from Spirit-empowered ministry.
3. The promise accompanies prophecy and visions, implying complementary modes of revelation rather than independent, competing ones.
4. The context of Pentecost establishes Christ’s exaltation as the ground for the gift; dreams are not an autonomous phenomenon but a by-product of the risen Lord’s gift of the Spirit.

Dreams in Apostolic Ministry after Pentecost

Although ἐνύπνιον itself does not recur, the wider narrative records God’s nocturnal guidance:
Acts 16:9 – Paul’s Macedonian vision opens Europe to the Gospel.
Acts 18:9 – The Lord encourages Paul in Corinth “in a vision of the night.”
Acts 27:23-24 – An angel assures Paul of safety during the storm.

These passages illustrate the ongoing reality of supernatural direction while simultaneously showing that such experiences are subordinate to the apostolic message already grounded in Scripture.

Historical Reflection

Early Church writers (e.g., Justin Martyr, Irenaeus) cite Joel 2 as evidence of the Spirit’s continuing activity, yet consistently measure all dreams by apostolic doctrine. The patristic consensus warns against dreams that contradict the faith once for all delivered.

Theological Significance

1. Continuity: Dreams link the eras of promise and fulfilment, demonstrating that the God of Abraham, Moses, and Joel is the same God who empowers the Church.
2. Eschatological Horizon: The “last days” began at Pentecost and will culminate at Christ’s return; dreams testify to that inaugurated reality.
3. Sufficiency of Scripture: While God may employ dreams, He never bypasses His written Word; Scripture is the definitive standard for testing every purported revelation (2 Timothy 3:16-17; 1 Thessalonians 5:20-21).

Pastoral and Practical Considerations

• Discernment: Believers are to “test the spirits” (1 John 4:1). Any dream that contravenes scriptural teaching must be rejected.
• Humility: God’s normal means of guidance remain Scripture, prayer, and wise counsel; dreams, if given, serve as confirmations, not replacements.
• Mission: Dreams often accompany frontier evangelism, especially where the written Word is scarce, echoing Acts 10:3-6 and Acts 16:9.
• Comfort: Many testimonies recount how the Lord uses dreams to reassure suffering saints, reflecting Job 33:15-18.

Summary

ἐνύπνιον encapsulates the biblical theme of God speaking through dreams, reaches its climactic New Testament usage in Acts 2:17, and reminds the Church that the same Spirit who inspired Scripture continues to work sovereignly, yet always in harmony with the apostolic truth once delivered to the saints.
