Thayer's Greek Lexicon
STRONGS NT 3455: μυκάομαι

μυκάομαι, μυκωμαι; (from μύ or μύ, the sound which a cow utters (Latinmugio)), to low, bellow, properly, of horned cattle (Homer, Aeschylus, Euripides, Plato, others); to roar, of a lion, Revelation 10:3.

Topical Lexicon
Etymology and Background

The verb expresses the deep, guttural bellow of large animals, evoking a sound that is both commanding and unmistakable. In the Greco-Roman world such a noise signified power, alarm, or the arrival of a formidable presence, ideas that readily transfer to the biblical portrait of God’s awesome self-disclosure.

Usage in Scripture

Only appearance: Revelation 10:3—“and he cried out in a loud voice like the roar of a lion. And when he cried out, the seven thunders sounded their voices.”

Literary Role in Revelation

1. Intensifies the scene: The roaring voice distinguishes the mighty angel from the ordinary, aligning him with the heavenly host whose utterances shake creation (Revelation 4:5; Revelation 8:5).
2. Signals divine authority: The comparison to a lion connects with earlier lion imagery for Christ (Revelation 5:5), underscoring that the angel’s message carries Christ’s royal mandate.
3. Introduces sealed revelation: The roar precedes the seven thunders whose content is withheld (Revelation 10:4), reminding readers that God retains mysteries even while revealing much.

Theological Significance

• Voice of the Sovereign: Throughout Scripture a thunderous or roaring voice marks the LORD’s majesty (Jeremiah 25:30; Amos 1:2). The verb therefore associates the angel’s cry with divine speech.
• Assurance amid judgment: The bellow is fearful yet purposeful; it heralds the completion of “the mystery of God” (Revelation 10:7), reassuring believers that history moves toward God’s ordained climax.
• Revelation and restraint: The roar leads to thunder that is deliberately sealed. God’s word is simultaneously proclaimed and concealed, teaching reverence for what remains undisclosed (Deuteronomy 29:29).

Historical and Cultural Insights

Ancient hearers knew the unsettling force of a lion’s roar echoing across valleys or a bull’s bellow resounding in a marketplace. John employs that cultural memory to depict a heavenly sound that cannot be ignored—far exceeding earthly terrors and demanding response.

Practical Ministry Application

1. Preaching: Communicate Scripture with clarity and weight, mirroring the angel’s authoritative proclamation (2 Timothy 4:2).
2. Worship: Encourage reverent awe; God still speaks with power, though often through His written Word, compelling humble submission (Psalm 29:3-4).
3. Pastoral counseling: When believers face overwhelming events, remind them that the same sovereign voice directing end-time events also shepherds their lives (John 10:27-28).

Related Themes and Cross-References

• Lion imagery—Genesis 49:9-10; Hosea 11:10; Revelation 5:5.
• Thunder as divine voice—Exodus 19:16-19; 1 Samuel 7:10; John 12:28-29.
• Sealed prophecy—Daniel 12:4; Revelation 10:4.

Christological Reflections

Although a mighty angel speaks, the roar’s likeness to a lion echoes the Lion of the tribe of Judah. The scene therefore anticipates Christ’s imminent assertion of kingship when the seventh trumpet sounds (Revelation 11:15).

Eschatological Emphasis

The verb highlights the irreversible momentum of the end times. Once the roar is heard, heaven’s countdown advances; “there will be no more delay” (Revelation 10:6). The Church is thus called to vigilance and faithful witness.

Worship and Homiletical Insights

The passage invites proclamation that balances majesty and mystery: God has spoken decisively in Christ, yet retains sovereign secrecy. True worship acknowledges both, fostering confidence without presumption.

Summary

Strong’s Greek 3455 portrays a resonant, authoritative roar that, in its single New Testament occurrence, magnifies God’s supremacy, urges readiness for final fulfillment, and models the tone with which His servants should declare His unchanging Word.
