King David’s final years were marked by a deep, inescapable chill. This severe cold was not merely a natural symptom of old age, but rather the result of a profound spiritual anxiety. A lingering fear had taken hold of him ever since he witnessed the destroying angel, an emotional tremor rooted in the remnants of his past failing with Bathsheba [אהבת יהונתן]. Because the King’s physical strength was completely depleted, his doctors understood that only the natural warmth of another human being could restore his body heat [מלבי״ם].
The royal servants and physicians devised a solution that blended physical healing with spiritual repair. They recommended finding a young virgin, as her body would naturally radiate more heat than an older woman [רש״י, רד״ק, צאינה וראינה]. The servants deliberately avoided bringing any of David's current wives or concubines to his bed. They feared that the presence of his wives might arouse him to physical intimacy, which would only further exhaust his severely weakened body [מלבי״ם]. Furthermore, David was legally forbidden from marrying this new young woman, as he already had eighteen wives, the absolute maximum permitted for a king [צאינה וראינה].
On a deeper level, bringing a beautiful young woman into his bed without engaging in any physical intimacy provided the ultimate spiritual correction for his earlier sin. True repentance is achieved when a person faces the exact same circumstances of temptation but refrains from acting, making this arrangement a complete and final repair for the King [אהבת יהונתן].
To prevent damaging gossip about the elderly king taking a young woman into his bed, the servants established an official position for her. She was to be constantly ready and available to serve him [מצודת דוד, ביאור שטיינזלץ]. Many commentators explain that she was given a formal title akin to a household manager or an overseer of the royal treasures and food. This respectable administrative cover allowed her to remain in his private quarters and lie in his embrace without causing public scandal [רלב״ג, מלבי״ם, אהבת יהונתן, ביאור שטיינזלץ]. However, other scholars argue that it would be entirely illogical to appoint a young girl as the royal treasurer. Instead, they suggest her title was not administrative at all. Rather, it simply described the physical act of providing warmth [רש״י, מצודת ציון], or referred to her general usefulness as someone bringing healing, help, and relief from the bitter cold [רד״ק].
This intimate medical arrangement carried heavy political consequences. Because it was highly immodest for the King to lie in bed with a young woman in the presence of others, he went into strict isolation. His regular servants, as well as his wives, including Bathsheba, were barred from his room. This total separation from the royal court allowed Adonijah to quietly plot his rebellion, fully aware that the King was entirely disconnected from outside events. It was only through the bold intervention of Nathan the Prophet that this wall of isolation was finally breached, bringing the critical news of the uprising directly to David [מלבי״ם].
