דברי הימים א, פרק כ״ז, פסוק ל״א

Managing a kingdom's vast wealth required specific expertise, and the appointment of individuals to oversee these resources was a deliberate process based on practical experience. The choice of Jaziz the Hagrite to oversee the flocks was a carefully considered decision tied directly to his background and specialized skills. The Hagrites were nomadic Arabs who dwelled in tents out in the open fields. Coming from this environment, Jaziz possessed a deep, natural mastery of raising and tending to sheep and goats [רש״י, ביאור שטיינזלץ].

All the individuals assigned to oversee these different domains are collectively recognized as the officials in charge of the royal property. The assets they managed encompassed every type of wealth belonging to the crown, ranging from silver and gold to agricultural fields, livestock, and all other movable goods. These selected men were the official administrators trusted to manage this entire portfolio of wealth on behalf of King David [מצודת דוד].
