King James wording
King James Version
When thou shalt hearken to the voice of the LORD thy God, to keep all his commandments which I command thee this day, to do that which is right in the eyes of the LORD thy God.THE KEY
Here, hearing is already a movement: the voice enters keeping, and keeping takes the shape of what is straight before God.
THE MEANING
The LORD’s voice is heard, held, and carried into what you do. “Right” carries the image of what is straight in the LORD’s sight, so listening and action belong to one relationship. The verse speaks of hearing that reaches your choices now.
WHAT THIS UNDOES
It undoes the belief that listening to God can remain inward while leaving your conduct untouched.
THE ROOT
תִּשְׁמַע
tishmaʿ
GROWS FROM
שׁמע
hear, listen; in this setting, hear and respond
“Hearken” can sound like receiving a sound, but שׁמע (shamaʿ, hear and respond) carries listening toward response. The verse binds hearing to keeping and doing, so the voice is more than information received.
ALSO GROWS
shemaʿ: Hear!
שְׁמַע
The imperative form uses the same root, making the call to hear in Deuteronomy 6:4 part of this same language of listening.
shemuʿah: Report, news; something heard
שְׁמוּעָה
This branch shows the root can name what reaches someone through hearing, while this verse carries hearing onward into action.
לִשְׁמֹר
lishmor
GROWS FROM
שמר
guard, watch over, keep
“Keep” can sound like simply retaining a rule, while שמר (shamar, guard and watch) carries the sense of attending to what is entrusted. The commandment is held like something watched over, linking listening with ongoing care.
ALSO GROWS
shomer: Keeper, guardian, one who watches
שֹׁמֵר
The guardian branch makes “keep his commandments” sound like active watchfulness, not passive storage.
mishmeret: Charge, watch, custody
מִשְׁמֶרֶת
This branch names an entrusted watch, illuminating the attentive quality carried by keeping.
הַיָּשָׁר
hayyāšār
GROWS FROM
ישר
be straight, level, upright
“Right” can sound like an abstract verdict, while ישר (yashar, straight and upright) holds the image of what is straight. The verse places that straightness in the LORD’s sight, giving the action a relational measure.
ALSO GROWS
yashar: Straight, upright
יָשָׁר
This form makes the concrete sense beneath “right” visible: what is aligned or straight.
yesharim: Upright ones
יְשָׁרִים
The plural form applies the same straightness to people, extending the root’s image beyond a single action.
THE PATTERN
A voice is truly heard when its hearing carries into action.
And Samuel said, Does the LORD delight in rising offerings and slaughtered offerings as much as in hearing and responding to the voice of the LORD? Behold, hearing and responding is better than a slaughtered offering; to prick the ear is better than the fat of rams.My sheep hear and respond to my voice, and I perceive them, and they follow me.But be makers of the word, and not hearers only, miscounting yourselves.THE THREAD
Hear and respond, O Israel. The LORD our God is one LORD.The opening word “Hear” is שְׁמַע (shemaʿ, hear and respond), from the same root as “hearken” here. Deuteronomy 13:18 opens that hearing into keeping and doing, showing how the voice continues through action.
