Proverbs warns that whoever leads the upright astray will fall 'into his own pit'—a vivid expression of poetic justice. The pit represents both a hunting trap and metaphorically any destructive scheme. The possessive 'his own' emphasizes the ironic reversal: the schemer's trap becomes his own doom. This wisdom saying reflects a moral principle found throughout biblical literature—evil boomerangs back on the evildoer. The pit one digs becomes the pit one occupies.
