And we have confidence in the Lord touching you, that ye both do and will do the things which we command you.

And we have confidence in the Lord touching you, that ye both do and will do the things which we command.

But we trust in the Lord as to you, that the things which we enjoin, ye both do and will do.

And we have confidence in the Lord concerning you, that ye both do and will do the things which we command you.

And we have confidence in the Lord in regard to you that you are doing, and will do, what we command.

And we have faith in the Lord about you, that you are doing and will do the things about which we give you orders.

And we have confidence about you in the Lord, that you are doing, and will continue to do, just as we have instructed.

Yes, and the confidence that our union with the Lord enables us to place in you leads us to believe that you are doing, and will do, what we direct you.

We have confidence. By this preface he prepares the way for proceeding to give the instruction, which we shall find him immediately afterwards subjoining. For the confidence which he says he has respecting them, made them much more ready to obey than if he had required obedience from them in a way of doubt or distrust. He says, however, that this hope, which he cherished in reference to them, was founded upon the Lord, inasmuch as it is his to bind their hearts to obedience, and to keep them in it; or by this expression, (as appears to me more probable,) he meant to testify, that it is not his intention to enjoin anything but by the commandment of the Lord. Here, accordingly, he marks out limits for himself as to enjoining, and for them as to obeying -- that it should be only in the Lord. [1] All, therefore, that do not observe this limitation, do to no purpose resort to Paul's example, with the view of binding the Church and subjecting it to their laws. Perhaps he had this also in view, that the respect which was due to his Apostleship might remain unimpaired among the Thessalonians, however the wicked might attempt to deprive him of the honor that belonged to him; for the prayer which he immediately subjoins tends towards this object. For provided men's hearts continue to be directed towards love to God, and patient waiting for Christ, other things will be in a desirable state, and Paul declares that he desires nothing else. From this it is manifest, how very far he is from seeking dominion for himself peculiarly. For he is satisfied provided they persevere in love to God, and in the hope of Christ's coming. In following up with prayer his expression of confidence, [2] he admonishes us that we must not relax in eagerness of prayer on the ground that we cherish good hope. As, however, he states here in a summary manner the things that he knew to be most necessary for Christians, let every one make it his endeavor to make proficiency in these two things, in so far as he desires to make progress towards perfection. And, unquestionably, the love of God cannot reign in us unless brotherly love is also exercised. Waiting for Christ, on the other hand, teaches us to exercise contempt of the world, mortification of the flesh, and endurance of the cross. At the same time the expression might be explained as meaning, the patience of Christ -- that which Christ's doctrine begets in us; but I prefer to understand it as referring to the hope of ultimate redemption. For this is the only thing that sustains us in the warfare of the present life, that we wait for the Redeemer; and farther, this waiting requires patient endurance amidst the continual exercises of the cross.

Footnotes

1 - "Voyci donc les bournes qu'il limite, et pour soy et pour eux: pour soy, de ne commander rien que par le Seigneur: a eux, de ne rendre obeissance sinon au Seigneur;" -- "Mark then the limits which he prescribes both for himself and for them: for himself, not to command anything but by the Lord: for them, not to render obedience except to the Lord."

2 - "Quand apres auoir protesté de sa confiance, il ne laisse pas d'adiouster encore la priere auec la confiance;" -- "When after having declared his confidence, he omits not to add besides, prayer along with confidence."

And we have confidence in the Lord - Not primarily in you, for you have hearts like others, but in the Lord. It is remarkable that when Paul expresses the utmost confidence in Christians that they will live and act as becomes their profession, his reliance is not on anything in themselves, but wholly on the faithfulness of God. He must be a stranger to the human heart who puts much confidence in it even in its best state; see Philippians 1:6; Philippians 4:7; 2-Timothy 1:12; compare Jde 1:24; Revelation 3:10; Proverbs 28:26.

And we have confidence - We have no doubt of God's kindness towards you; he loves you, and will support you: and we can confide in you, that ye are now acting as we have desired you, and will continue so to do.

(3) And we have confidence in the Lord touching you, that ye both do and will do the things which we command you.
(3) The second admonition is, that they always follow the doctrine of the apostles as a rule for their life.

And we have confidence in the Lord touching you,.... The ground of confidence concerning them was not in themselves, in their grace, and strength, and wisdom, and conduct, and good behaviour; but in the Lord, in his grace and strength, and in the power of his might, without whom they could do nothing, but through him strengthening them, could do all things.
That ye both do, and will do the things which we command you; referring both to the commandments, which they had already given them by Christ, and they had showed, and continued to show a proper regard unto, see 1-Thessalonians 4:1 and also to what would be observed to them, as in 2-Thessalonians 3:6.

we have confidence in the Lord--as "faithful" (2-Thessalonians 3:3). Have confidence in no man when left to himself [BENGEL].
that ye both do--Some of the oldest manuscripts insert a clause, "that ye both have done" before, "and are doing, and will do." He means the majority by "ye," not all of them (compare 2-Thessalonians 3:11; 2-Thessalonians 1:3; 1-Thessalonians 3:6).

We trust in the Lord concerning you - Thus only should we trust in any man.
