The twilight of King David's life marks a critical transition of power. His extreme physical weakness is not merely a historical detail, but the catalyst for the events that follow. It explains why Adonijah felt emboldened to rebel and seize the throne, creating an urgent need to crown Solomon while his father was still alive [מלבי״ם, אלשיך, אברבנאל]. Furthermore, David's failing health sets the stage for the arrival of Abishag the Shunammite, who soon becomes a key figure in the political struggle against Adonijah [אברבנאל].
David is described with a dual expression of aging. One aspect highlights his outward appearance, such as white hair and wrinkles, which can sometimes appear prematurely. The other emphasizes his actual chronological age, confirming that he had indeed lived a long life, reaching the age of seventy after a forty-year reign [מצודת דוד, אברבנאל, רד״ק]. Yet, seventy is not an age that typically brings about a complete physical collapse. David aged prematurely, losing his natural body heat due to a combination of physical and emotional tolls. His life was defined by grueling wars that drained his strength [רד״ק, צאינה וראינה, שטינזלץ], alongside deep sadness and anxiety stemming from the family tragedies involving Amnon and Absalom. Additionally, he subjected himself to frequent fasting and self-denial as part of his repentance. His custom of staying awake past midnight to engage in Torah study and prayer further exhausted his physical form [אברבנאל, אהבת יהונתן].
As his health declined, his attendants tried to warm him with heavy layers of blankets and bedding, but to no avail [רד״ק, שטינזלץ]. Blankets do not generate warmth on their own; they simply trap and insulate the body's natural heat. Because David's internal body heat had completely faded, layers of fabric could not help him. This prompted his servants to seek a medical solution in the form of a natural, human source of warmth [מלבי״ם, רלב״ג, אברבנאל].
Beyond the physical and medical explanations, two primary traditions trace David's deep chill to past spiritual events. The first approach suggests a consequence based on his past actions: whoever disrespects clothing will ultimately find no benefit from it. Because David once secretly cut the corner of King Saul's robe in a cave, he was punished in his old age when clothing refused to provide him warmth. The second tradition links his condition to the sheer terror he experienced upon seeing the Angel of Death standing over Jerusalem with a drawn sword during the plague. That immense fear froze his blood, leaving his body permanently cold [רש״י, רד״ק, צאינה וראינה, אברבנאל].
