Job reflects on a deeply rooted commitment to kindness and caring for the vulnerable in society. Mercy and charity are not portrayed as occasional good deeds, but as the very core of his identity, woven into his existence from his earliest days.
The primary approach among commentators is that the focus here is on the traits of charity, honesty, and compassion toward the poor. In a striking image, the virtue of kindness itself is seen as having raised and educated Job, acting as a guiding father figure. From the time he was born, he embraced and actively practiced this way of life [רש״י, רמב״ן, ביאור שטיינזלץ, מצודת ציון]. This description is an intentional exaggeration meant to show how completely devoted he was to doing good, making it seem as though he and the trait of charity were inseparably bound together [מצודת דוד].
Taking a more direct approach to the subjects of his care, another perspective suggests that Job actively raised the fatherless. An orphan grew up alongside him as if Job were his own father, while Job also guided and supported the widow through her struggles [אבן עזרא, רלב״ג].
A more personal interpretation frames this as a reflection on Job's own life story. In this view, God is the one who stepped in as a father to raise an orphaned Job. Experiencing this divine care, Job learned to watch over and provide for his own widowed mother from his youth. Recognizing the kindness God showed Him, Job feels a deep duty to pay it forward by caring for other orphans and widows. He trusts that by continuing this cycle of compassion, God will continue to shower him with goodness and treat him with that same unending mercy [מלבי״ם, אלשיך].
