Nehemiah 1-3

Nehemiah was a cheerleader for rebuilding the wall of Jerusalem. One of the families he motivated was Shallum son of Hallohesh (3:12). His family joined him in the work. But the passage is somewhat confusing because it states that his daughters worked with him. Was Shallum a hard driving man who forced his daughters to toil on the wall? Or was Nehemiah such an effective motivator that the daughters of Shallum desired to participate in the effort? If Shallum had no sons then it seems likely that the daughters sought to participate in the work with their father.
