This scripture is not a blanket statement that implies we should not work. The scripture specifies that "the laborer in Zion" should not work for money, meaning you should not be paid when you are doing service for the Church. We don’t get paid when we minister to others. In some churches, however, ministers are paid—it is a job. The concern expressed in verse 31 is turning the holy service of the priesthood into a commercial activity. Another interpretation of this scripture might be a warning not to let your job become so all-consuming that you become obsessed with money. That would also be a problem.
