brethren--This exhortation to "warm (Greek, 'admonish,' as in Th1 5:12) the unruly (those 'disorderly' persons, Th2 3:6, Th2 3:11, who would not work, and yet expected to be maintained, literally, said of soldiers who will not remain in their ranks, compare Th1 4:11; also those insubordinate as to Church discipline, in relation to those 'over' the Church, Th1 5:12), comfort the feeble-minded (the faint-hearted, who are ready to sink 'without hope' in afflictions, Th1 4:13, and temptations)," applies to all clergy and laity alike, though primarily the duty of the clergy (who are meant in Th1 5:12)." support--literally, "lay fast hold on so as to support." the weak--spiritually. Paul practiced what he preached (Co1 9:22). be patient toward all men--There is no believer who needs not the exercise of patience "toward" him; there is none to whom a believer ought not to show it; many show it more to strangers than to their own families, more to the great than to the humble; but we ought to show it "toward all men" [BENGEL]. Compare "the long-suffering of our Lord" (Co2 10:1; Pe2 3:15).
