The ultimate reward granted to the king transcends temporary, earthly success, elevating him to an eternal state of holiness and divine closeness. God not only surrounds the king with continuous blessings [ביאור שטיינזלץ], but transforms him into the very essence of an eternal blessing [אלשיך]. The primary approach among commentators is that the king's name becomes a lasting standard for future generations. Even after his passing, people will bless one another with the hope that they might achieve his level of greatness [רד״ק, מצודת דוד]. This enduring blessing extends to his descendants [רד״ק, אבן עזרא], with some viewing it as a channel through which all nations will ultimately be blessed [מאירי]. Historically, this reflects the prophetic promise delivered to King David, ensuring that his royal dynasty would endure forever through God's unending kindness [מלבי״ם].
Accompanying this eternal legacy is an experience of profound happiness. This joy is amplified to an extraordinary degree, emphasizing the sheer magnitude of the emotion [רד״ק]. Yet, this is not an ordinary, fleeting feeling; it represents a supreme and unique spiritual joy [מלבי״ם באור המילות]. In the physical world, moments of great happiness must often be tempered with caution, lest a person become careless and stumble into sin. However, this future spiritual joy will be entirely complete, pure, and completely liberated from any fear of negative inclinations [אלשיך].
The true source of this overwhelming joy is not rooted in material wealth or military might, but in the intimate experience of existing directly before God [מאירי, ביאור שטיינזלץ]. The king's ultimate success stems from the reality that God turns toward him, shines His presence upon him, and grants him direct providence [רד״ק]. It is this very experience of God's presence that produces absolute joy [מצודת דוד]. Commentators offer different perspectives on the nature of this divine closeness. It can be understood as King David sitting before God with absolute, unwavering trust in His kindness [מלבי״ם]. Alternatively, it describes the ultimate spiritual reward experienced in the Garden of Eden, echoing an early Rabbinic tradition that applies this entire concept to the Messianic king, who will one day achieve an unparalleled closeness to God [רש״י].
