The Hebrew word neker means misfortune, calamity, or that which is strange and unfamiliar. It derives from the root nakar (H5234), meaning to recognize or to treat as foreign. The word carries the sense of adversity that comes as something unexpected or alien — a disruption of the normal order of life that is hard to comprehend or accept.
In the Old Testament, neker describes the kind of calamity that befalls the wicked or that disrupts the lives of the faithful. The concept connects to the broader biblical theme of suffering and adversity — how God's people navigate seasons of misfortune while trusting in His sovereignty. Job's experience exemplifies how calamity can seem utterly foreign and inexplicable, yet faith holds firm in the conviction that God remains in control even when circumstances seem strange and hostile.
