The leadership of the Messianic King introduces an era where absolute justice and extraordinary spiritual power completely replace the need for weapons and military force. He stands as a shield for the vulnerable while casting dread upon those who commit evil. When evaluating the claims of the destitute, his judgment rests entirely on prophecy, divine providence, and the laws of the Torah. This spiritual foundation ensures he is never swayed by false arguments or the common human tendency to favor the wealthy and powerful [אבן עזרא, מלבי״ם, רד״ק, אברבנאל]. Instead, he judges with perfect fairness, actively caring for the poor and securing their salvation [ביאור שטיינזלץ].
His relationship with the humble takes two distinct forms according to commentators. On one hand, he directly guides the modest and good people along a straight path. Because he understands their readiness to accept moral growth, his correction is delivered with soft and gentle words [רש״י, אבן עזרא, מלבי״ם, ביאור שטיינזלץ]. On the other hand, his guidance serves to defend the lowly against their oppressors. He fiercely rebukes the strong and wealthy on behalf of the weak, extracting justice from the hands of the corrupt to ensure they can no longer exploit others [רד״ק, מצודת דוד, מצודת ציון, אברבנאל, שד״ל].
The sheer might of the King is most evident in his ability to rule without swords, soldiers, or executioners. His words alone serve as his weapon [ביאור שטיינזלץ, אברבנאל]. When his speech strikes the land, he is primarily targeting the wicked [רש״י, רד״ק, מצודת דוד], though some suggest his authority commands such awe that all inhabitants of the earth fear him and naturally refrain from wrongdoing [שד״ל].
The lethal power of his speech is understood in several ways. Some view the description of his breath destroying the wicked as a poetic repetition to emphasize his authority [מצודת דוד]. Others interpret it as a literal, open miracle, where his mere curse brings actual death to rebellious nations or individual sinners through divine messengers, echoing the miracles of the early prophets [רד״ק, אברבנאל]. A subtle distinction is noted regarding his power: while he uses his full, primary speech to strike the earth at large, the faintest breath remaining on his lips is enough to eliminate a single wicked person [מלבי״ם, מצודת ציון]. Conversely, this destruction can be understood metaphorically. Rather than issuing a standard physical death sentence, which any mortal ruler can do, the King's profound wisdom and hatred of violence create an atmosphere of absolute authority. When this wise ruler, who knows the hidden secrets of the heart, simply opens his mouth to speak, the heart of the wicked dies within them and turns to stone from overwhelming terror [שד״ל].
