2. Thessalonicher 3:3

From evil - Απο του πονηρου may be translated, from the devil or from the evil one. They had disorderly men, wicked men, and the evil one or the devil, to contend with; God alone could support and give them the victory; he had promised to do it, and he might ever be confided in as being invariably faithful.

faithful--alluding to "faith" (Th2 3:2) : though many will not believe, the Lord (other very old manuscripts read "God") is still to be believed in as faithful to His promises (Th1 5:24; Ti2 2:13). Faith on the part of man answers to faithfulness on the part of God. stablish you--as he had prayed (Th2 2:17). Though it was on himself that wicked men were making their onset, he turns away from asking the Thessalonians' prayers for HIS deliverance (Th2 3:2 : so unselfish was he, even in religion), to express his assurance of THEIR establishment in the faith, and preservation from evil. This assurance thus exactly answers to his prayer for them (Th2 2:17), "Our Lord . . . stablish you in every good word and work." He has before his mind the Lord's Prayer, "Lead us not into temptation, but deliver us from evil"; where, as here, the translation may be, "from the evil one"; the great hinderer of "every good word and work." Compare Mat 13:19, "the wicked one."

But the Lord is faithful,.... Or "God" as the Vulgate Latin and Ethiopic versions read, as do also the Alexandrian and Claromontane copies. This is said for the comfort of the saints, lest they should be discouraged upon hearing that all professors of faith in Christ had it not, who might be ready to take it to themselves, and fear, that either they had it not, or if they had, that they might lose it, and fall from it. Wherefore the apostle observes to them the comfortable attribute of God's faithfulness, which he will not suffer to fail. He has promised many things, and he is faithful that has promised, who also will do them, nor will any good thing he has promised ever fail. Who shall stablish you: in the doctrines of the Gospel, so as not to be moved away from them, or be finally and totally seduced by those unreasonable and wicked men; and also in the grace of faith, which though it may be weakened, and there may be a falling from a degree of the steadfastness of it, as to its act and exercise, yet it shall never finally and totally fail, he who is the author will be the finisher of it; and likewise in the profession both of the doctrine and grace of faith, which true believers shall hold fast unto the end; for God will not suffer the righteous to be moved, or to depart from him; he has promised them perseverance, and he is faithful to give it to them. And keep you from evil: from the evil of sin; not from the being and commission of it entirely, which is not to be expected in this life; but from the dominion of it, at least from its reigning unto death, and from the damning power of it: and also from that evil one Satan; from his snares and temptations, so as to be entangled and overcome by them; for God is faithful, who will not suffer his to be tempted beyond the…

In the close of the foregoing chapter, the apostle had prayed earnestly for the Thessalonians, and now he desires their prayers, encouraging them to trust in God, to which he subjoins another petition for them (Th2 3:1-5). He then proceeds to give them commands and directions for correcting some things he was informed were amiss among them (Th2 3:6-15) and concludes with benedictions and prayers (Th2 3:16-18).

3:3 The sufferings the Thessalonians faced were caused by the evil one (or by evil; see 2:9; cp. 1:4-6; 1 Thes 1:6; 2:14).
