At the culmination of his reflections, King David strikes a delicate balance between absolute trust in divine promises and a deep recognition of human dependence on the Creator. He expresses complete certainty that God will bring the good He started to its perfect conclusion. The primary approach among commentators is that this reflects a profound sense of security. Just as God began to bless David and keep His promises, He will carry that kindness through to ultimate salvation [רד״ק, מצודת דוד, המאירי]. God does not abandon His actions halfway, ensuring His name is never dishonored [מלבי״ם]. Another perspective views this thought as a personal plea, asking God to answer David's prayers and fulfill his deepest wishes entirely [רש״י, אבן עזרא, ביאור שטיינזלץ]. Alternatively, this completion is connected directly to the building of the Temple. Since David was prevented from constructing it himself, he prays that God will finish the monumental task through his son Solomon [חומת אנך].
Central to this trust is the acknowledgment that God's kindness is eternal and unchanging. This enduring benevolence does not depend on human actions; rather, it flows directly from God's very essence [מלבי״ם]. Some link this eternal kindness to the specific prophecy delivered by Nathan, which promised David that his royal dynasty would be established forever [אלשיך].
Rooted in this eternal kindness is a heartfelt plea for God not to abandon the work of His hands. The primary approach among commentators is that this refers to humanity, and specifically to David himself. He reminds God that He created, raised, and crowned him, asking Him not to let go, much like a father who never abandons his child [רד״ק, מצודת דוד, אבן עזרא, המאירי, מלבי״ם]. This concept naturally extends to all people, who constantly rely on divine support [ביאור שטיינזלץ]. Conversely, another approach interprets the work of God's hands as a reference to the Temple. Here, the prayer is that God will not forsake His chosen home, particularly the future Third Temple, which is destined to be built by God Himself and endure eternally [רש״י, חומת אנך]. Blending these ideas, a unified view presents a dual prayer for both humanity and the future Temple. As the two great works of God's hands, David prays that He will prepare and perfect them both together [אלשיך].
