King James wording
King James Version
Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.THE KEY
The verse calls unbelief a direction of the heart: distrust does not stay inside but becomes a standing-away from the living God.
THE MEANING
The warning speaks into the reader’s present inner life: distrust can settle into the heart and take shape as withdrawal from the living God. Here unbelief is more than a private idea; it is a relationship losing its orientation toward life.
WHAT THIS UNDOES
It undoes the belief that unbelief is only a private opinion with no consequence for relationship: this verse gives it a direction, away from the living God.
THE ROOT
ἀπιστίας
apistias
GROWS FROM
πειθ- / πιστ- (peith- / pist-)
Persuade, bring into trust; the πιστ- word family carries the sense of trust and reliability.
“not leaning your full weight” in this verse is apistias. The word joins a negation to the word family for trust: it names the absence of reliance, the refusal to lean your full weight on God. The verse links that inward distrust to an outward movement away from the living God.
ALSO GROWS
peithō: Persuade; trust or be persuaded.
πείθω
It points beneath unbelief to the question of what the heart trusts enough to rely on.
pistis: Trust, reliance, confidence.
πίστις
This is the positive form of the same word family, making the verse’s “unbelief” a failure of trust rather than merely a lack of information.
pistos: Trustworthy, reliable.
πιστός
The family also describes what can be relied on, bringing the question of trust into view.
ἀποστῆναι
apostēnai
GROWS FROM
ἀπό + ἵστημι (apo + histēmi)
Stand away; withdraw or take a position apart.
The word for departing carries the image of standing away. The verse presents distrust as a movement of relationship: the heart’s mistrust takes shape as withdrawal from the living God.
ALSO GROWS
aphistēmi: Withdraw, depart, stand away.
ἀφίστημι
This verb family makes the separation in “departing from” concrete as an act of withdrawal.
apostasis: Departure, withdrawal, rebellion.
ἀπόστασις
The related noun preserves the same movement away, showing how standing apart can become a settled departure.
THE PATTERN
A heart’s trust sets its direction: distrust toward God becomes withdrawal, while trust keeps a person turned toward him.
For they did not lean their weight on God, and did not lean their full weight on his deliverance.Thus says the LORD, Cursed is the man who leans his full weight upon man, and sets flesh as his arm, and whose heart turns aside from the LORD.But we are not of those who shrink back into perishing, but of those who lean their full weight into the gathering of a living soul.THE THREAD
But we are not of those who shrink back into perishing, but of those who lean their full weight into the gathering of a living soul.The word rendered “unbelief” in Hebrews 3:12, ἀπιστία (apistia, lack of trust), shares the πιστ- (pist-) word family with πιστεύω (pisteuō, trust or believe) in this verse. Hebrews 10:39 makes the movement visible by setting “draw back” against “believe.”
