When the wicked face justice and the world's order shifts, the fate of those who quietly maintained their faith through deep hardship is entirely transformed. Salvation brings a profound wave of happiness that heals past suffering and proves that their trust in God was never in vain.
These faithful individuals are recognized as righteous people who lived in a state of extreme lowliness and poverty [ביאור שטיינזלץ]. They showed immense humility and patience, having quietly accepted God's decrees and carried His burdens [רש"י]. Furthermore, they silently endured the arrogance of corrupt people who thrived at their expense [שד"ל]. Their intense neediness reflects a state of lacking everything, leaving them yearning and longing for relief [מצודת ציון]. They were, in essence, the poorest and most despised members of society [שד"ל].
Their happiness springs from witnessing the promises of comfort finally coming true. After enduring a long period where the wicked held power and caused them suffering, these righteous individuals see that their hope was justified. As corrupt leaders and dishonest judges meet their downfall, the faithful are granted rescue, relief, and honor [רד"ק, מצודת דוד, אבן עזרא]. This resulting happiness does not appear out of nowhere. Instead, it builds directly upon the deep faith and trust in God that they already possessed long before their troubles even began [רד"ק, מצודת דוד].
The primary approach among commentators is that these descriptions of humility and neediness are simply two ways of referring to the exact same group of righteous people [רד"ק, מצודת דוד]. However, a different perspective suggests that these descriptions actually highlight two distinct groups experiencing God's revelation in different ways [מלבי"ם]. The humble represent the righteous who always maintained their belief in God by recognizing His constant, natural guidance in the world. For them, this new happiness is simply an addition to a steady joy they already felt. In contrast, the needy represent the simple masses who struggled to see God in the everyday natural world and, as a result, had not yet experienced this joy. Their reaction will be a sudden, overwhelming burst of new enthusiasm, sparked by witnessing obvious miracles and wonders that completely defy the laws of nature.
