This verse in the King James

King James wording
But the prophet, which shall presume to speak a word in my name, which I have not commanded him to speak, or that shall speak in the name of other gods, even that prophet shall die.

To speak in God’s name is to claim God’s nature, and the verse makes that claim answerable to whether God actually commanded the word.

Speaking ⁨בִּשְׁמִי⁩ (bishmi, “in my name/nature”) claims to represent God’s own nature; borrowing that name does not make a self-appointed word God’s. The verse states the consequence without softening it: the presumptuous prophet, and the one speaking in the names of other gods, shall die. Its boundary remains sharp wherever divine authority is invoked: the source matters, and false attribution carries judgment.

WHAT THIS UNDOES

A divine-sounding claim is not self-authenticating: invoking God’s name does not turn an uncommanded word into God’s word.

יָזִיד

yazid

GROWS FROM

זוד

z-w-d

To boil or seethe; in this form, to act presumptuously.

“who boils over” in this verse is yazid. The same three consonants name boiling stew and presumptuous action. That echo lets “presumption” carry the image of a word boiling up from its speaker, set here against a word actually commanded by God.

ALSO GROWS

nazid: Boiled stew or pottage

נָזִיד

Genesis 25:29 uses this word for Jacob’s pottage; its shared root opens an unexpected link between the verse’s presumption and something boiling up.

zedim: Presumptuous or proud ones

זֵדִים

Psalm 19:13 uses this related form for “presumptuous sins,” showing the same root’s connection to self-assertion.

צִוִּיתִיו

tsivvitiv

GROWS FROM

צוה

ts-w-h

To command, charge, or direct.

⁨צִוִּיתִיו⁩ (tsivvitiv, “I commanded him”) names the commission the presumptuous word lacks. Beside ⁨שֵׁם⁩ (shem, “name/nature”), it makes the claim precise: the speaker invokes God’s nature, but the verse asks whether God directed the speech.

ALSO GROWS

mitsvah: Commandment or instruction

מִצְוָה

This familiar branch shows the same root in a noun for a command; the speech in this verse is measured against what God actually commands.

tsav: Command or charge

צַו

This shorter form carries the root’s direct sense of an issued charge, sharpening the contrast with a word that the speaker presumes on their own.

A voice claiming divine authority is accountable to its actual source; borrowing a name does not make a word commissioned.

I have not sent these prophets, yet they ran; I have not spoken to them, yet they prophesied.
Jeremiah 23:21 · SDVIt draws the same line between a prophet’s motion and God’s sending: they run and prophesy though God neither sent nor spoke.
They have seen emptiness and lying divination, saying, The LORD says; and the LORD has not sent them; and they have made others wait, that they might make the word stand.
Ezekiel 13:6 · SDVThe claim “The LORD saith” collapses when there was no sending, and the verse names the resulting speech as vain and deceptive.
Many will say to me on that day, Lord, Lord, did we not prophesy in your nature, and by it throw out demons, and in it do many works of strength?
Matthew 7:22 · SDVThe speakers point to works done in Jesus’ name; invoking that name alone does not establish that the speech and works carry his authority.
And Jacob boiled a stew, and Esau came from the field, and he was faint.
Genesis 25:29 · SDV

The Hebrew word for Jacob’s pottage, ⁨נָזִיד⁩ (nazid, “boiled stew”), shares the ⁨זוד⁩ (z-w-d) root with ⁨יָזִיד⁩ (yazid, “act presumptuously”) here. That shared root lets the ordinary pot throw light on “presumption”: a word can boil up from its speaker, while this verse distinguishes that from what God commands.
