This verse in the Selah Decoded Version

The Hebrew ties “the word” and “spoken” to one root, so the question is whether the utterance truly comes from the source it claims.

The question is alive in the reader’s own heart: when a word claims the LORD as its source, how is that source known? The Hebrew connects “word” and “spoken,” while “know” asks for perception of the utterance’s source. The verse gives this question a place without treating the claim itself as proof.

WHAT THIS UNDOES

A message does not become the LORD’s word merely because someone attributes it to him.

הַדָּבָר

haddāḇār

GROWS FROM

ד־ב־ר

To speak; as a noun, davar can mean word, matter, or affair.

English presents “word” and “spoken” as separate ideas, but both come from ⁨ד־ב־ר⁩: the noun and the act of speaking carry one root. The question concerns the source of the utterance itself, whether this word belongs to the LORD’s speech.

ALSO GROWS

dāḇār: Word, matter, or affair.

דָּבָר

This is the word whose source the verse asks how to recognize.

dibbēr: He spoke.

דִּבֵּר

This form of the same root appears in “which the LORD hath not spoken.”

נֵדַע

nēdaʿ

GROWS FROM

י־ד־ע

To know, perceive, or recognize.

“know” in this verse is nēdaʿ. Yada can name knowing and perceiving, while daʿat names knowledge. Here the question is how to recognize the source of a claimed utterance, not merely how to hear its claim.

ALSO GROWS

yādaʿ: To know or perceive.

יָדַע

This is the root behind “How shall we know,” the verse’s question of recognition.

daʿat: Knowledge or understanding.

דַּעַת

This related form shows the same root carrying the idea of what is known or understood.

A claim that bears divine authority is discerned through testing and its observable fruit.

When a prophet speaketh in the name of the LORD, if the thing follow not, nor come to pass, that is the thing which the LORD hath not spoken, but the prophet hath spoken it presumptuously: thou shalt not be afraid of him.
Deuteronomy 18:22 · KJVThe claim is tested by whether what was spoken comes to pass.
Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
1 John 4:1 · KJVThe verse calls for testing claims of spiritual source rather than accepting them at face value.
Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
Matthew 7:16 · KJVRecognition comes through what a source brings forth.
When a prophet speaketh in the name of the LORD, if the thing follow not, nor come to pass, that is the thing which the LORD hath not spoken, but the prophet hath spoken it presumptuously: thou shalt not be afraid of him.
Deuteronomy 18:22 · KJV

The noun “word” and the verb “spoken” in verse 21 both grow from ⁨ד־ב־ר⁩; verse 22 repeats that root as it names the test. It makes the question concrete: the source of the claimed word is discerned by whether what was spoken comes to pass.
