A crushing disconnect exists between a life lived with moral purpose and a reality filled with sudden tragedy. Job expresses the painful gap between his righteous actions and the disaster that has overtaken him. Having shown deep compassion for others and shared the sadness of the poor and needy, he naturally expected to find goodness and mercy during his own time of distress [ביאור שטיינזלץ]. Instead, a bitter punishment fell upon him, treating him as though he were a sinner receiving exactly what his actions deserved [רש״י, מצודת דוד].
As Job reflects on his situation, he describes his anticipation using two distinct concepts of expectation: a general hope and a confident wait [מצודת ציון]. There is a fundamental difference between the two. A person hopes for something that is not guaranteed, but they wait for something that is entirely certain. Job deliberately speaks of waiting when it comes to the arrival of light, because the coming of light is understood to be an absolute and predetermined event [מלבי״ם].
This confident wait for light is not merely a poetic thought, but a reliance on a spiritual promise. There is an assurance that whoever comforts the poor and shares in their sadness will have their light shine through the darkness. Because Job had wept for those facing hard times and grieved for the needy, he waited with absolute certainty for that promised light to arrive. Tragically, his reality was turned upside down. Not only did the promised light fail to shine in his personal darkness, but even the light he previously possessed vanished entirely, replaced only by deep gloom [אלשיך].
