1 Thessalonians 4:12

that ye may walk becomingly toward them that are without, and may have need of nothing. [Instead of spending their time in restless gadding about or idle meddling with other people's affairs, Paul expected them to heed his warning, and earn their own living. These Thessalonians were mostly of the laboring class. If they were idle, they would quickly be reduced to dependence or beggary, and the unbelieving world without (Colossians 4:5) would quickly say of the new religion that it made men idle and worthless. Paul therefore counsels them to that industry that would make them independent, self-respecting and respected.]
