King James wording
King James Version
A man void of understanding striketh hands, and becometh surety in the presence of his friend.THE KEY
The verse’s “void of understanding” is literally “lacking heart,” so the reckless handshake begins as an absence of inner weighing before it becomes a binding promise.
THE MEANING
When you guarantee a friend’s obligation without weighing its cost, the risk becomes yours. The Hebrew calls this “lacking heart” (חֲסַר־לֵב, ḥăsar-lēḇ), locating the failure in discernment before the hand ever strikes.
WHAT THIS UNDOES
It undoes the belief that a promise made for a friend carries no real cost: the pledge makes the guarantor responsible too.
THE ROOT
חֲסַר־לֵב
ḥăsar-lēḇ
GROWS FROM
חסר
ḥ-s-r
To lack, be deficient, or fall short.
The phrase literally means “lacking heart”: לֵב (lev, heart) names the inner center of thought and resolve. The warning is that a pledge can expose a failure to weigh its consequences before the commitment is made.
ALSO GROWS
maḥsôr: A state of lacking.
מַחְסוֹר
It echoes the verse’s diagnosis: something necessary for sound judgment is absent.
ḥesrôn: A shortcoming or deficiency.
חֶסְרוֹן
It makes the lack concrete: the missing thing is not information, but discernment about what the guarantee entails.
עֹרֵב
ʿōrēḇ
GROWS FROM
ערב
ʿ-r-b
To guarantee or stand surety for another.
“surety” in this verse is ʿōrēḇ. The Hebrew places the guarantor alongside the pledge itself, making the commitment explicit: the person takes responsibility for a guarantee. A friend’s presence does not keep that obligation from reaching the one who gives it.
ALSO GROWS
ʿāraḇ: To take responsibility for another’s obligation.
עָרַב
This verbal form shows that surety is an act of assuming liability, not just expressing support.
ʿărubbāh: A guarantee or pledged security.
עֲרֻבָּה
This is the pledged obligation beside the guarantor in the verse, revealing what the hand-clasp carries.
תּוֹקֵעַ
tōqēaʿ
GROWS FROM
תקע
t-q-ʿ
To thrust, drive in, or strike.
“strikes his palm” in this verse is tōqēaʿ. “Striketh hands” uses a verb from the root for thrusting or driving something in, giving the hand-clasp the force of an enacted commitment. The gesture is a public act of binding, not a casual touch.
ALSO GROWS
tāqaʿ: To thrust or set something firmly in place.
תָּקַע
This branch sharpens the sense of a hand striking to make a pledge that fixes responsibility.
teqiʿāh: A blast or signal made by sounding a trumpet.
תְּקִיעָה
It shows the root can also mark a forceful, outwardly heard act, fitting the pledge’s public character.
THE PATTERN
A binding promise to carry another’s risk is a commitment whose cost must be weighed before the hand is given.
My son, if you have entangled yourself for your companion, if you have struck your palms with a stranger.He who mingles himself with a stranger's pledge smarts for it, but the one who hates the striking of hands rests secure.For which of you, wanting to build a tower, does not first sit down and count the cost, whether he has enough to finish it?THE THREAD
My son, if you have entangled yourself for your companion, if you have struck your palms with a stranger.This verse repeats the same surety and hand-striking language, showing that the gesture itself enacts a guarantee. Its next verse calls the speaker snared by his own words, making clear how an unweighed pledge can bind the one who gives it.
