דברי הימים א, פרק כ״ז, פסוק ט״ו

King David established a highly systematic military structure by dividing his forces into monthly rotating shifts. Throughout the year, a dedicated guard of twenty-four thousand men was assigned to serve each month. The commanders appointed to lead these divisions were selected directly from David’s elite warriors. This specific arrangement suggests that the force functioned essentially as a reserve army [ביאור שטיינזלץ].

During the twelfth month of the year, the military division was placed under the command of Heldai the Netophathite. His family lineage is specifically noted to trace back to Othniel the son of Kenaz. There is a general consensus among commentators that highlighting this ancestry serves to connect Heldai directly to the very first judge of the Israelites, emphasizing his distinguished family background.
