This verse in the King James

King James wording
I, even I, am he that comforteth you: who art thou, that thou shouldest be afraid of a man that shall die, and of the son of man which shall be made as grass;

The question “who art thou?” places your identity in the care of the One comforting you, while the person you fear remains mortal.

You are being comforted by God where fear fixes on another person’s power. The person before you is mortal, and the son of Adam is as brief as grass; the verse holds that vulnerability in view while asking who you are in the presence of your Comforter.

WHAT THIS UNDOES

It undoes the belief that a human threat becomes ultimate simply because it feels immediate.

אֱנוֹשׁ

ʾĕnōš

GROWS FROM

אנש

ʾ-n-š

Frailty, weakness, or sickness.

“frail one who will die” in this verse is ʾĕnōš. English “man” can sound like a neutral category; ⁨אֱנוֹשׁ⁩ (enosh), a mortal human, foregrounds frailty. The verse points your fear toward someone already bounded by death.

ALSO GROWS

ʾĕnōš: A human being; a mortal.

אֱנוֹשׁ

This is the word for the person you fear: the verse names their mortality within the question.

ʾānūš: Sick or incurable.

אָנֻשׁ

This related form carries the root’s sense of frailty; it makes the human limit in the verse more visible.

בֶּן־אָדָם

ben-ʾādām

GROWS FROM

אדם

ʾ-d-m

Humanity associated with the ground or soil.

“son of man” in this verse is ben-ʾādām. The Hebrew phrase names the son of Adam, the ground-being. Beside the image of grass, that ground connection makes human vulnerability part of the verse’s picture.

ALSO GROWS

ʾādām: A human being; an earthling.

אָדָם

The phrase identifies the one feared as a son of Adam, a member of ground-bound humanity.

ʾădāmāh: Ground or soil.

אֲדָמָה

The word related to Adam recalls humanity’s connection to the ground, alongside the verse’s image of grass.

מְנַחֶמְכֶם

menaḥemkhem

GROWS FROM

נחם

n-ḥ-m

To console or comfort; in other forms, to relent or feel regret.

“comforteth you” in this verse is menaḥemkhem. The verse presents consolation as something God is doing for you now. This root can also describe relenting, so its word-family carries the sense of a responsive change of posture.

ALSO GROWS

neḥāmāh: Consolation or comfort.

נֶחָמָה

This noun names the consolation that the verb says God is giving you.

niḥam: Relented, felt regret, or was comforted.

נִחַם

The same root can name a changed response; here, comfort is an active response to the person under pressure.

God’s presence relocates fear by placing mortal threats beside a sustaining presence.

Comfort, comfort my people, says your God.
Isaiah 40:1 · SDVThe same Hebrew root ⁨נחם⁩ (naḥam, comfort or console) speaks consolation directly to the person addressed.
The LORD is at my side; I do not fear. What can humankind do to me?
Psalm 118:6 · SDVThe psalm places human threat beside the LORD’s presence, as Isaiah does.
So that we may boldly say, The LORD is my helper, and I will not fear. What will a human do to me?
Hebrews 13:6 · SDVThe verse voices the same reordering of fear through the presence of the Lord.
Comfort, comfort my people, says your God.
Isaiah 40:1 · SDV

Both verses use ⁨נחם⁩ (naḥam, comfort or console): here God is comforting you, and there consolation is spoken directly to God’s people. The shared root opens “comforteth you” as an active address, not an abstract reassurance.
