True leadership requires a foundation far stronger than human capability. A leader's absolute trust in divine providence serves as the ultimate guarantee of their stability. The primary approach among commentators is that a king's genuine source of power does not come from personal bravery, military might, or the sheer number of citizens supporting him. Instead, his security relies on God alone [רד״ק, אבן עזרא, מאירי].
The king places his complete trust in divine kindness. God is recognized as the highest authority to emphasize His exclusive control over the world. He has the absolute ability to save whomever He chooses, entirely independent of physical or military force. Furthermore, all the good that God brings to His creations flows directly from His pure kindness [רד״ק]. Because the king maintains this unwavering trust, he is assured that he will never fall from his throne or lose his royal standing [רש״י, מצודת דוד, ביאור שטיינזלץ]. There is a delicate contrast at play: it is precisely by leaning on the One who is highest that the king is kept from falling down [אבן עזרא].
Beyond securing physical and political stability, this dual trust in God and His kindness provides the king with profound spiritual and moral resilience. Relying completely on divine grace ensures that even during periods of extraordinary success and overwhelming joy, the king will remain grounded. He will not lose his direction, stumble, or wander away from the proper path [אלשיך].
