This verse in the King James

King James wording
If I bear witness of myself, my witness is not true.

A voice cannot authenticate itself; testimony becomes established when another witness confirms it.

This verse meets the reader wherever a claim about identity or reality is being made: the self alone cannot make its testimony stand as established truth. Here, “not true” means the witness is insufficient on its own, not necessarily that the speaker is lying.

WHAT THIS UNDOES

The belief that personal certainty makes a claim self-validating.

μαρτυρῶ

martyrō

GROWS FROM

μαρτυρ-

to bear witness or testify

“bear witness” in this verse is martyrō. Greek keeps bearing witness and testimony in one word family, where English can make them feel like separate ideas. The verse shows that testimony spoken by the self alone cannot supply its own confirmation.

ALSO GROWS

martys: witness; one who testifies

μάρτυς

This names the person who bears witness, linking the act in this verse to the one who speaks as a witness.

martyria: testimony; witness

μαρτυρία

This names the testimony itself, the same word family that appears in John 8:17 when the testimony of two is called true.

ἀληθής

alēthēs

GROWS FROM

ἀληθ-

true, genuine, truthful

The word means true or genuine, while the conditional here focuses on whether a witness stands when it comes from the self alone. The claim is not necessarily a lie; it lacks confirmation beyond the speaker.

ALSO GROWS

alētheia: truth

ἀλήθεια

This noun belongs to the same word family and names the truth that testimony is meant to establish.

alēthinos: genuine; real

ἀληθινός

This related form echoes the distinction between testimony that merely asserts itself and testimony established as genuine.

Testimony becomes established through confirmation from more than one witness.

One witness shall not rise up against a man for any crookedness, or for any falling short, in it he misses the mark; upon the mouth of two witnesses, or upon the mouth of three witnesses, the word shall stand.
Deuteronomy 19:15 · SDVThe matter is established through the testimony of multiple witnesses rather than the claim of one alone.
But if he does not hear you, take along with you one or two more, so that upon the mouth of two or three witnesses every word may stand.
Matthew 18:16 · SDVA word gains standing when other witnesses confirm it.
This is the third time I am coming to you. In the mouth of two or three witnesses shall every word stand.
2 Corinthians 13:1 · SDVThe same pattern makes corroboration the ground on which a word is established.
And in your instruction it stands written, that the witness of two people is true.
John 8:17 · SDV

John 8:17 uses ⁨μαρτυρία⁩ (martyria), meaning testimony, from the same word family as “bear witness” here. It makes the hidden condition plain: testimony becomes established through a witness beyond the self.
