3:6-15 Those who have received the gospel, are to live according to the gospel. Such as could work, and would not, were not to be maintained in idleness. Christianity is not to countenance slothfulness, which would consume what is meant to encourage the industrious, and to support the sick and afflicted. Industry in our callings as men, is a duty required by our calling as Christians. But some expected to be maintained in idleness, and indulged a curious and conceited temper. They meddled with the concerns of others, and did much harm. It is a great error and abuse of religion, to make it a cloak for idleness or any other sin. The servant who waits for the coming of his Lord aright, must be working as his Lord has commanded. If we are idle, the devil and a corrupt heart will soon find us somewhat to do. The mind of man is a busy thing; if it is not employed in doing good, it will be doing evil. It is an excellent, but rare union, to be active in our own business, yet quiet as to other people's. If any refused to labour with quietness, they were to note him with censure, and to separate from his company, yet they were to seek his good by loving admonitions. The Lords is with you while you are with him. Hold on your way, and hold on to the end. We must never give over, or tire in our work. It will be time enough to rest when we come to heaven.

6. we command you—Hereby he puts to a particular test their obedience in general to his commands, which obedience he had recognized in 2Th 3:4.

withdraw—literally, "to furl the sails"; as we say, to steer clear of (compare 2Th 3:14). Some had given up labor as though the Lord's day was immediately coming. He had enjoined mild censure of such in 1Th 5:14, "Warn … the unruly"; but now that the mischief had become more confirmed, he enjoins stricter discipline, namely, withdrawal from their company (compare 1Co 5:11; 2Jo 10, 11): not a formal sentence of excommunication, such as was subsequently passed on more heinous offenders (as in 1Co 5:5; 1Ti 1:20). He says "brother," that is, professing Christian; for in the case of unprofessing heathen, believers needed not be so strict (1Co 5:10-13).

disorderly—Paul plainly would not have sanctioned the order of Mendicant Friars, who reduce such a "disorderly" and lazy life to a system. Call it not an order, but a burden to the community (Bengel, alluding to the Greek, 2Th 3:8, for "be chargeable," literally, "be a burden").

the tradition—the oral instruction which he had given to them when present (2Th 3:10), and subsequently committed to writing (1Th 4:11, 12).

which he received of us—Some oldest manuscripts read, "ye received"; others, "they received." The English Version reading has no very old authority.
