This verse in the King James

King James wording
My mouth shall speak the praise of the LORD: and let all flesh bless his holy name for ever and ever.

The verse gathers one speaking mouth and all flesh into a blessing of the LORD’s name, ⁨שֵׁם⁩ (shem), the nature made known.

Your voice belongs to a praise that reaches beyond you: all flesh is named in the blessing of the LORD’s set-apart nature. This blessing carries through the ages, joining the individual voice to a shared act of recognition.

WHAT THIS UNDOES

Praise is only private or belongs to one kind of person; the verse places all flesh within the blessing.

יְבָרֵךְ

yevarekh

GROWS FROM

ברך

Bless; the same root also names the knee.

“bless” in this verse is yevarekh. The root joins blessing to the body: ⁨בֶּרֶךְ⁩ (berekh, knee) and ⁨בְּרָכָה⁩ (berakhah, blessing) share its letters. Here all flesh blesses the LORD’s name, so the act of blessing belongs to embodied life, not only inward thought.

ALSO GROWS

berekh: Knee

בֶּרֶךְ

This branch gives the blessing a bodily resonance: all flesh is involved.

berakhah: Blessing

בְּרָכָה

This is the noun from the same root as the verse’s verb, tying the spoken act to blessing itself.

תְּהִלָּה

tehillah

GROWS FROM

הלל

Praise, celebrate, speak in honor of.

The word for praise grows from the same root as the praise-command that names the Psalms. English can make this sound like a single utterance; the root connects this mouth’s praise to a whole songbook of praise.

ALSO GROWS

hallel: Praise

הַלֵּל

This is the same root in the familiar call to praise, making the verse’s spoken praise part of a wider chorus.

tehillim: Praises; the Psalms

תְּהִלִּים

The word for the collection of Psalms shares the root, linking this single verse to the book’s larger practice of praise.

קָדְשׁוֹ

qodsho

GROWS FROM

קדש

Set apart, distinguished as belonging wholly to God.

“holy” in this verse is qodsho. The LORD’s name is described as set apart: ⁨שֵׁם⁩ (shem, name as nature) points to the nature made known, while ⁨קדש⁩ marks that nature as belonging wholly to God. The verse does not separate praise from what the name reveals.

ALSO GROWS

qadosh: Set apart

קָדוֹשׁ

This adjective carries the root’s sense into the description of the LORD’s name.

qodesh: Set-apartness; what is set apart

קֹדֶשׁ

This noun makes explicit the quality the verse attaches to the LORD’s name.

Praise expands from an individual voice to the recognition of God by all creation.

Let every thing that has breath praise the LORD. Praise the LORD.
Psalm 150:6 · SDVThe closing call of the Psalms widens praise to every breathing thing.
For it is written, "As I live, says the Lord, every knee shall bend to me, and every tongue shall speak out to God."
Romans 14:11 · SDVEvery knee and tongue join in acknowledging God, echoing this verse’s blessing by all flesh.
And every created thing in heaven, and on the earth, and under the earth, and in the sea, and all that is in them, I hear them saying, Blessing, and honor, and weight, and power, be to the one who sits upon the throne, and to the Lamb, into the ages of the ages.
Revelation 5:13 · SDVThe praise reaches every creature and every realm, voicing the universal blessing named here.
Let every thing that has breath praise the LORD. Praise the LORD.
Psalm 150:6 · SDV

The Hebrew for “praise” here, ⁨תְּהִלָּה⁩ (tehillah), and “praise” in Psalm 150:6 share the root ⁨הלל⁩ (halal). Psalm 145 gathers all flesh to bless the LORD’s name; Psalm 150 opens that chorus to every breathing thing.
