Job’s declaration of innocence reaches its peak as he presents the exceptionally high moral standard he set for himself. He claims his intense suffering is entirely unjustified because he maintained absolute purity, controlling not only his actions but his very thoughts and sense of sight. To achieve this purity, Job made a firm commitment to restrict his vision. The primary approach among commentators is that he deliberately avoided looking at anything forbidden, such as a married woman, or anything else that might awaken improper desire [רש"י, מצודת דוד, תקות אנוש]. Going even further, he restricted his gaze from completely permissible worldly matters if he had no practical need for them [אבן עזרא, אלשיך].
His extraordinary piety is especially clear in his refusal to gaze at an unmarried woman. This avoidance does not refer to a casual glance, but to a deep, prolonged look [מצודת ציון]. While it is fundamentally permitted to look at a single woman to determine if she is a suitable match for marriage for oneself or one's son, Job took on a stricter standard. He avoided even this, allowing only the briefest look necessary for a basic introduction [מצודת דוד, אלשיך, ביאור שטיינזלץ].
Commentators offer several reasons for this extreme caution. Job worried that if he examined a single woman and she later married someone else, he might find himself still thinking about her [רש"י]. Others emphasize that staring at a woman merely to evaluate her beauty is a sign of foolishness and wickedness, not wisdom [רמב"ן]. By keeping his distance, Job ensured that his physical desires could not take control and lead him toward sin [תקות אנוש]. His boundaries were so absolute that he even avoided looking at the garments she wore [חומת אנך].
A slightly different perspective connects this strictness to Job's habit of playing music to entertain brides and grooms at their weddings. According to this view, Job declares that even when he looked at a bride, he did so exclusively to fulfill the commandment of bringing joy to the newly married couple, completely free from any personal desire [מלבי"ם].
Ultimately, Job established all of these personal boundaries because of his deep awareness of God’s constant supervision. He understood that God watches every path a person takes, and that whoever fails to guard their eyes will eventually face divine judgment and punishment [אבן עזרא, תקות אנוש].
