The Greek word mykáomai, represented by G3455, means to bellow or roar. Derived from a word meaning to "moo," it describes a deep, powerful sound. It is a highly specific term, appearing only 1 time in 1 unique verse in the entire Bible, making its single usage particularly significant.
The sole appearance of G3455 is in Revelation 10:3, during a dramatic apocalyptic vision. A mighty angel is described as having "cried with a loud voice, as when a lion roareth." This act of roaring is not merely a sound but a powerful proclamation that elicits a direct response from the heavens, as "seven thunders uttered their voices" immediately after. The verse pairs the action of roaring G3455 with crying out G2896 and a loud G3173 voice G5456, emphasizing the immense authority and power behind the angel's message.
Several related words provide context for the power and nature of this sound:
- G3023 léōn (a "lion"): This word is directly linked to G3455 in its only scriptural use Revelation 10:3. The lion is a symbol of both messianic authority, as with the "Lion of the tribe of Juda" Revelation 5:5, and of a fearsome adversary 1 Peter 5:8.
- G2896 krázō (to "croak" (as a raven) or scream, i.e. to call aloud): This word is used in parallel with G3455 in Revelation 10:3. It often describes an urgent or desperate cry, such as the souls under the altar calling for judgment Revelation 6:10 or believers calling to God as "Abba, Father" Romans 8:15.
- G1027 brontḗ (thunder): This is the direct result of the angel's roar in Revelation 10:3. Thunder is consistently associated with the awesome power and presence of God's throne in heaven (Revelation 4:5, Revelation 11:19).
The theological weight of G3455 is concentrated in its singular, powerful context.
- Divine Authority: The act of roaring like a lion G3023 is a display of ultimate power and authority. The sound G3455 is not one of simple speech but a divine bellow that commands the attention of creation and precedes a significant heavenly event.
- Initiating Revelation: The roar serves as a catalyst. It is the action that causes the seven thunders G1027 to utter G2980 their own voices Revelation 10:3-4. This positions the roar as the trigger for a divine message, one so profound it had to be sealed.
- Apocalyptic Proclamation: The use of G3455 instead of a more common word for speaking, like G2980, signifies the unique and overwhelming nature of the angel's cry. It is a sound befitting the gravity of the end times, conveying a message with the force of a lion's roar.
In summary, G3455 is a rare verb that carries immense theological force in its single appearance. Used exclusively in Revelation 10:3, it describes a sound of supreme authority and power, likened to the roar of a lion. It functions as the trigger for a heavenly response from the seven thunders, underscoring its role as a key element in the unfolding of apocalyptic events. The word demonstrates how a specific, powerful term can define the tone and significance of a pivotal moment in scripture.
