מלכים א, פרק ט״ו, פסוק ה׳

The enduring survival of the Davidic dynasty rests entirely on King David's absolute loyalty to the will of God. This unwavering dedication became the standard for all future kings of Judah. God supported these later rulers specifically because of David's uprightness, granting them power as long as they clung to God's path, while punishing them when they abandoned it [אברבנאל, ביאור שטיינזלץ, מצודת דוד]. The historical record notes only a single exception to David's lifelong devotion. Paradoxically, isolating this one severe failure serves as a powerful testimony to his overall righteousness. It proves that in every other action throughout his life, he behaved properly and never strayed from the correct path [רלב״ג].

Because the account specifically restricts David's wrongdoing to the matter of Uriah the Hittite, commentators deduce that his actions involving Bathsheba were not actually considered a sin [אברבנאל, מצודת דוד]. This is explained by the military practice of the time: soldiers departing for David's wars would write conditional bills of divorce for their wives, meaning Bathsheba was technically an unmarried woman when David took her [מצודת דוד]. Additionally, there is a perspective that she was fundamentally destined to be with David from the very beginning [אברבנאל].

Since the relationship with Bathsheba was not the core transgression, the failure lies strictly in the specific circumstances surrounding Uriah [חומת אנך]. One approach explains that David condemned Uriah as a rebel against the crown for refusing a direct royal order to return to his home. David's true failure here was his lack of deeper investigation into his soldier's motives. Uriah had actually refused to go home out of a profound reverence for God, feeling it was highly inappropriate to find comfort at home while the Ark of the Covenant remained out on the active battlefield. A different perspective suggests the sin is rooted in the exact manner of Uriah's death. Uriah fell by an Ammonite sword, which was engraved with an idol. By orchestrating a situation where Uriah was killed by this specific weapon, David indirectly lent power and validation to the enemy's idolatrous practices [חומת אנך].
