This verse in the King James

King James wording
And so terrible was the sight, that Moses said, I exceedingly fear and quake:)

The Greek ties the sight’s terror to Moses’ fear with the same root, then gives his trembling a separate word of its own.

When an encounter exceeds what the reader can contain, fear can reach both the inner life and the body as trembling. The text leaves that terror visible without explaining it away.

WHAT THIS UNDOES

The holy must always feel safe and comforting; here the sight is terrible enough to leave Moses afraid and trembling.

φοβερόν

phoberon

GROWS FROM

φοβ-

phob-

Fear, dread, or being struck with alarm.

“awesome” in this verse is phoberon. The word rendered “terrible” shares its phob- root with the word for Moses’ fear, ⁨ἔκφοβος⁩ (ékphobos). The sight’s terror and Moses’ fear belong to one word family; a second root then names his trembling.

ALSO GROWS

ékphobos: Fear-struck; terrified.

ἔκφοβος

This is the word used for Moses’ response, joining his fear directly to the sight’s terror.

phobos: Fear; dread.

φόβος

This noun shows the wider family beneath both “terrible” and “exceedingly fear.”

ἔντρομος

entromos

GROWS FROM

τρομ-

trom-

Trembling or bodily shaking.

The word rendered “quake” comes from a different Greek root than fear. The verse lets alarm and bodily trembling remain distinct, while showing how closely they meet in Moses’ response.

ALSO GROWS

tromos: Trembling; shaking.

τρόμος

This noun names the trembling that the adjective ⁨ἔντρομος⁩ describes in Moses.

tremō: To tremble; to shake with fear.

τρέμω

This verb shows the root as an embodied action rather than an inward feeling alone.

An overwhelming encounter is registered in the body, as fear becomes trembling rather than remaining an idea.

And on the third day, in the morning, there were thunders and flashes, and a heavy cloud upon the mount, and the sound of the ram's horn was very strong, so that all the people who were in the camp trembled.
Exodus 19:16 · SDVThe mount’s thunder, fire, and trumpet culminate in the people’s bodily trembling, echoing Moses’ response here.
And I was with you in weakness, and in fear, and in much trembling.
1 Corinthians 2:3 · SDVFear and much trembling appear together again, naming alarm and its bodily expression as joined realities.
Therefore, my beloved, as you have always heard and responded, not as in my presence only, but now much more in my absence, work out your own deliverance with fear and trembling.
Philippians 2:12 · SDV

Philippians 2:12 places fear, ⁨φόβος⁩ (phobos), beside trembling, ⁨τρόμος⁩ (tromos), the same two Greek word families opened here. The pairing shows that “fear and quake” gathers two distinct dimensions, alarm and bodily shaking, rather than repeating one sensation.
