And that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you;
Study to be quiet, х philotimeisthai (G5389)] - 'make it your ambition to be quiet, and to do your own business.' In contrast to the world's ambition 'to make a great stir,' and the restlessness of fanatical 'busybodies' (2 Thessalonians 3:11-12).
Work with your own hands. B C Delta G f g, Vulgate, omit "own" [idiais]. A 'Aleph (') have it. The Thessalonian converts were, it seems, chiefly of the working classes. Their expectation of Christ's immediate coming led some enthusiasts to neglect their daily work, and be dependent on others (end of 1 Thessalonians 4:12). The expectation was right so far as that the Church should be always looking for Him; but they were wrong in making it a ground for neglecting daily work. The evil, as it subsequently became worse, is more strongly reproved (2 Thessalonians 3:6-12).
