The record of those returning to Zion shifts to highlight a group with a highly unique social standing. Though tasked with simple, unrespected manual labor, these individuals possessed a deep and enduring bond with the Temple and its daily operations. Their attachment to the nation was so profound that they willingly chose to leave exile, return to the Land of Israel, and resume their modest duties [שטיינזלץ].
The primary approach among commentators is that this specific group, known as the Nethinim, were actually the descendants of the ancient Gibeonites. Their title stems from a historical decision made by Joshua, who assigned them to serve as woodchoppers and water drawers for the community and the needs of the Temple. This service also provided them with their livelihood [רש״י, מצודת דוד, אבן עזרא]. Before this assignment, they were known simply as Gibeonites. However, from the moment they were dedicated to the Temple's upkeep, their identity shifted, and they became known as the Nethinim, meaning those who were given over to service.
While other biblical records mention that King David and his officers assigned the Nethinim to assist the Levites, this does not represent a new decree. Rather, David was merely upholding and reaffirming the original arrangement established generations earlier by Joshua [אבן עזרא]. The specific names recorded in this account, such as the descendants of Ziha, Hasupha, and Tabbaoth, represent the distinct family lines of these dedicated workers who made the journey back to the land [שטיינזלץ].
