דברי הימים ב, פרק ו׳, פסוק ט׳

The building of the Temple represents a profound generational shift, establishing a clear division of roles between father and son. Although King David deeply desired to construct the holy building and prepared all the necessary materials for it, he was strictly prohibited from erecting the structure himself [מצודת דוד].

When reflecting on this history, King Solomon carefully frames the narrative. He chooses not to mention the explicit reason for his father's disqualification—the fact that David was a man of war. Instead, the focus is directed toward the future. Because Solomon is a man of rest and peace, he is the one uniquely destined to complete the grand vision that his father so passionately sought to realize [ביאור שטיינזלץ].

To emphasize the direct lineage required for this sacred task, the narrative notes that the chosen son will emerge directly from David. It respectfully refers to the waist area as a gentle euphemism for reproduction, highlighting the physical continuity between the king who dreamed of the Temple and the son who would actually build it [מצודת ציון].
