Jeremiah’s warning against trusting in man

Jeremiah’s warning against trusting in man sets human reliance against trust in the Lord, and the novel returns to that opposition at moments of helplessness, betrayal, and threatened sacrifice. Its force is not merely proverbial: it supplies a scriptural vocabulary for lives exposed to other people’s violence, while the surrounding biblical scenes test what it means to refuse help or entrust oneself to another.

The Warning and Its Promise

The passage gives the rule both a curse and a blessing. It begins, “Cursed is the man, says Jeremiah, that trusteth in man,” and describes the person who makes “flesh his arm” as a heath in the desert, inhabiting “a salt land and not inhabited.” Against that barren image stands the person whose hope is in the Lord: “a tree planted by the waters,” whose leaves remain green even when heat comes and drought persists. The contrast is between exposed, sterile dependence and a sustaining source that outlasts adverse conditions.

The warning also turns inward. Alongside the promise of flourishing, the passage declares that “the heart is deceitful above all things, and it is desperately sick.” Its distrust is therefore not only a judgment on unreliable people around the sufferer; it questions the heart that decides whom to trust. The passage offers no easy assurance that human judgment can identify a safe source of help.

Job and the Refusal of Help

The text places the problem of trust beside Job’s ruin. Having lost everything, Job lies in a cabbage patch near a dog’s kennel, keeping just beyond the watchdog’s reach. The animal barks, strains at its chain, and snaps whenever he tries to rise. The passage makes the desolation concrete: the palace, gardens, fields, watchdog, and goats once belonged to Job, yet he no longer recognizes them as his.

The address to Job insists on the possibility of help even as it names his resistance: “it’s up to you, Job, you just don’t want it.” That insistence complicates a simple reading of the warning as a command to withdraw from all human reliance. Job’s plight is narrated through the loss of everything he possessed, but the voice addressing him treats refusal itself as part of the predicament. The question is not only whether others can be trusted; it is also whether the sufferer can accept aid.

Human Trust Under Pressure

The warning returns in abbreviated form immediately before the attack on Franz Biberkopf in the car. The Jeremiah passage names the deceitful heart and the person who trusts in man; the action then makes betrayal bodily and immediate. Reinhold secretly signals to the other man, puts a hand on the door handle beside Franz Biberkopf, and, as the car speeds along, seizes him and forces him toward the open door. The scriptural language thus precedes a scene in which apparent companionship becomes danger, giving the warning a concrete human context rather than leaving it as detached commentary.

A nearby image of water sharpens the contrast. The promised tree draws life from waters, but the text also evokes black waters lying silent beneath a storm-torn forest, untouched by the wind above and filled with rot. The images do not simply repeat one another: water can signify a sustaining source, while the black pool is still and dreadful. The passage’s biblical promise of endurance therefore sits within a larger landscape where apparent calm does not guarantee safety.

Sacrifice, Obedience, and Preservation

During sleep associated with Tegel Prison, Franz Biberkopf sees a father lead his son through a long journey into the mountains toward an altar. The son fears the knife and the father admits his own fear, yet the command to sacrifice presses them toward an act neither can treat as ordinary. The scene turns on the son’s eventual willingness and the father’s readiness; at the decisive moment, the Lord calls them to stop, and both fall on their faces. They are told they will live.

This episode makes trust more difficult than a general injunction either to rely on people or to reject them. The father and son are bound by a relationship in which each must consent, while the divine voice finally interrupts the killing. The scene does not erase the danger of human dependence that Jeremiah names; instead, it gives the narrative a distinct image of obedience halted before sacrifice is completed.

Later, Death’s song also shifts the biblical imagery of loss toward preservation. Death says, “I am not just a mower, I am not just a sower, here I have to be because my task is to preserve,” and ends each stanza with “O yes!” Against the warning’s image of barrenness, the claim that Death’s task is to preserve leaves open a different relation between destruction and continuance. Across Job’s deprivation, Franz Biberkopf’s betrayal, and the spared son, Jeremiah’s warning becomes part of a recurring inquiry into where help can be found—and what, in the end, can still be kept alive.
