This verse in the King James

King James wording
Lo, I will bring a nation upon you from far, O house of Israel, saith the LORD: it is a mighty nation, it is an ancient nation, a nation whose language thou knowest not, neither understandest what they say.

The threat is not only a nation coming from far away; its speech is a distance you cannot cross, because you cannot know its tongue or hear its words.

The LORD says he is bringing a nation against you, strong, old, and distant. You do not know its tongue, and its speech remains beyond your understanding. The verse holds the threat and the estrangement together: the approaching force is beyond your familiarity and comprehension.

תִשְׁמַע

tishma

GROWS FROM

שמע

Hear, listen.

The Hebrew verb means “hear” where the KJV says “understandest.” The verse moves from not knowing the tongue to not hearing what is spoken, revealing that the barrier reaches the act of receiving speech.

ALSO GROWS

shama: Hear, listen.

שָׁמַע

This is the root verb in the verse: the foreign speech cannot be heard as something the listener understands.

shemu'ah: A report or news, something heard.

שְׁמוּעָה

This branch shows how hearing carries what is reported; here, the words cannot arrive as intelligible news.

לְשֹׁנוֹ

leshono

GROWS FROM

לשן

Tongue; by extension, language.

The word translated “language” is literally “his tongue.” The unfamiliarity is not an abstract difference between peoples: the verse locates it in the tongue that carries speech.

ALSO GROWS

lashon: Tongue; language.

לָשׁוֹן

The word names both the physical tongue and the language it carries, tying bodily speech to shared understanding.

lashon hara: An evil tongue; slander.

לְשׁוֹן הָרָע

The phrase keeps the tongue visible as the instrument of speech; here, the barrier is that the tongue’s words cannot be understood.

תֵדַע

teda

GROWS FROM

ידע

Know, perceive.

“knowest” in this verse is teda. The word for knowing points to recognition by encounter, not simply possession of information. The nation’s tongue is outside the listener’s familiarity, so its speech has no shared ground from which to be received.

ALSO GROWS

da'at: Knowledge, knowing.

דַּעַת

This noun makes the gap explicit: the tongue is outside what the listener knows.

madda: Knowledge, understanding.

מַדָּע

The shared root links the verse’s failure to know a language with the broader absence of recognized understanding.

When people cannot know or hear one another’s language, speech becomes a barrier to shared meaning.

Come, let us go down, and there mix up their lip, so that they may not hear one another's lip and respond.
Genesis 11:7 · SDVConfounded language prevents people from understanding one another, turning speech into separation.
When this voice arose, the crowd came together and was poured into confusion, because each one heard them speaking in his own tongue.
Acts 2:6 · SDVEach person hears the speech in a language they know, showing how shared language opens access to what is said.
So if I do not perceive the strength of the voice, I will be a babbler to the one who speaks, and the one who speaks will be a babbler to me.
1 Corinthians 14:11 · SDVWithout understanding the voice, speaker and listener become strangers to each other.
The LORD shall lift up a nation against you from far, from the edge of the earth, as the eagle swoops; a nation whose tongue you shall not understand;
Deuteronomy 28:49 · SDV

Deuteronomy uses ⁨לָשׁוֹן⁩ (lashon, tongue or language) and ⁨שָׁמַע⁩ (shama, hear) in its warning about a nation coming from far. Jeremiah repeats that root pattern: the approaching nation is distant in place, and its speech is beyond the hearer.
