True greatness in leadership is not measured by vast conquests or rule over many nations, but by how the weakest members of society are treated. The ultimate power of the ideal king, the Messiah, is revealed through his deep humility and his dedication to protecting the defenseless.
Commentators explore the relationship between the king's global influence and his care for the vulnerable. One approach suggests that his dedication to justice is the exact reason all nations will love and serve him, as they witness his commitment to those who have no support [רד״ק]. Alternatively, his widespread global dominance is seen as a direct reward for his strict practice of justice and his efforts to save the oppressed from their abusers [מצודת דוד, מלבי״ם].
While the primary approach among commentators understands the victims as everyday people living in poverty, a unique perspective views this as a political metaphor. In this light, the vulnerable subject actually represents a weaker king whom the Messiah takes under his wing, protecting him from a more powerful ruler [אבן עזרא].
When stepping in to help the weak, the king addresses different levels of need, both within and outside his borders [ביאור שטיינזלץ]. He rescues the person who has absolutely nothing and cries out bitterly to be saved from a stronger oppressor [מאירי, ביאור שטיינזלץ]. The king does not wait only for the dignified, quiet individuals who are too ashamed to protest the injustice done to them; he actively saves even the most ignored person screaming for help in the streets [אלשיך]. At the same time, he looks after the ordinary poor, ensuring his assistance is not limited only to those who have hit rock bottom [אלשיך].
The reality that these victims have no one else to help them reveals the king's unique way of governing. Instead of simply appointing local judges or sending officials to handle the problem, the king takes personal responsibility. Because the vulnerable person stands completely alone, the king steps in directly and saves him, without relying on his servants [אלשיך, מלבי״ם].
