What Does Deuteronomy 31:21 Mean in the King James?

And it shall come to pass, when many evils and troubles are befallen them, that this song shall testify against them as a witness; for it shall not be forgotten out of the mouths of their seed: for I know their imagination which they go about, even now, before I have brought them into the land which I sware.

This verse in the Selah Decoded Version

The song stays in their mouths because an inner pattern can be forgotten by the people who live it.

A formed inclination is already known before the promised arrival, and the song continues to testify when trouble comes. What is carried in the mouth outlives the moment and gives the hidden pattern a voice.

WHAT THIS UNDOES

It undoes the belief that hardship creates the inner pattern or that the inward pattern remains unseen: it is already known, and the song gives it a public witness.

יֵצֶר

yetzer

GROWS FROM

י־צ־ר

y-ts-r

to form, fashion, or shape

“imagination” in this verse is yetzer. Yetzer names what is formed within: an inclination, design, or bent of thought. The verse says this formation is already known before arrival in the land, so the song’s witness brings an existing pattern into speech rather than creating it.

ALSO GROWS

yatsar: to form or fashion

יָצַר

The same verbal seed makes the imagination a formed inclination, not merely a passing thought.

yotser: potter; one who forms

יוֹצֵר

The potter’s image makes the formative sense visible: an inclination has shape and direction.

עֵד

ed

GROWS FROM

עוּד

ʿ-w-d

to bear witness or testify

A witness gives testimony that stands against denial. Here the song itself occupies that role and remains embodied in the next generation’s speech.

ALSO GROWS

edut: testimony or witness

עֵדוּת

This branch names the testimony the song preserves beyond the moment of trouble.

he'id: to testify or bear witness

הֵעִיד

The verb shows the song acting as a speaker that testifies against the people.

A witness preserves truth beyond the will of those it confronts.

Now therefore write ye this song for you, and teach it the children of Israel: put it in their mouths, that this song may be a witness for me against the children of Israel.
Deuteronomy 31:19 · KJVThe song is placed in the people’s mouths so its testimony remains present among them.
And Joshua said unto all the people, Behold, this stone shall be a witness unto us; for it hath heard all the words of the LORD which he spake unto us: it shall be therefore a witness unto you, lest ye deny your God.
Joshua 24:27 · KJVThe stone stands as a witness that keeps the people’s spoken commitment before them.
Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another;)
Romans 2:15 · KJVConscience bears witness within, making the inward record speak.
And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
Genesis 6:5 · KJV

Both verses use ⁨יֵצֶר⁩ (yetzer), the formed inclination or design. Genesis names it as an inward pattern; Deuteronomy says that pattern is already known and sets a remembered song beside it as witness.
