Knowing, that as However there might be some of the Corinthians that were drawn away for the time by the calumnies of the false Apostles, so as to entertain less honorable views of Paul, on seeing him shamefully handled before the world, he, nevertheless, associates them with himself both in fellowship of afflictions, and in hope of consolation. [1] Thus he corrects their perverse and malignant view, without subjecting them to an open rebuke.

1 - The Corinthians were koinonoi partakers of, or in communion with him in his afflictions. What is more humble and lowly (ti tapeinophronesteron) than Paul in this expression? saith Chrysostom -- they who had not in the least measure shared with him in sufferings, yet he maketh them copartners with him. They are, as Salmeron expresseth it, Copartners in the gain and in the loss with Paul. They venture (as it were) in the ship together." -- Burgesse. -- Ed.

And our hope of you is steadfast - We have a firm and unshaken hope in regard to you; we have a confident expectation that you will be saved. We believe that you will be enabled so to bear trial as to show that you are sustained by the Christian hope; and so as to advance your own piety, and confirm your prospect of heaven.
As ye are partakers of the sufferings - It is evident from this, that the Corinthians had been subjected to trials similar to those which the apostle had endured. It is not known to what afflictions they were then subjected; but it is not improbable that they were exposed to some kind of persecution and opposition. Such trials were common in all the early churches; and they served to unite all the friends of the Redeemer in common bonds, and to make them feel that they were one. They had united sorrows; and they had united joys; and they felt they were tending to the same heaven of glory. United sorrows and united consolations tend more than anything else to bind people together. We always have a "brotherly" feeling for one who suffers as we do; or who has the same kind of joy which we have.

And our hope of you is steadfast - We have no doubt of your continuing in the truth; because we see that you have such a full, experimental knowledge of it, that no sufferings or persecutions can turn you aside. And we are sure that, as ye suffer, so shall ye rejoice.

For our hope of you is steadfast,.... We have long ago entertained hopes of you, that the work of God is begun upon your souls, and will be carried on, and that you will hold on in the profession of your faith unto the end, and not be moved by the afflictions you see in us, or endure in yourselves; and so will pass on cheerfully in your Christian race, in the midst of all your troubles, and rejoice in hope of the glory of God, you may expect to be possessed of; and this hope, for or concerning you, continues with us firm and immovable.
Knowing, which may refer either to the Corinthians; so the Arabic version, "be ye knowing", or "know ye"; you may, or should know; this you may assure yourselves of: or to the apostle and other ministers; so the Syriac version, "we know", we are persuaded of the truth of this,
that as you are partakers of the sufferings; that is, of Christ, and the same which we also suffer for him:
so shall ye be; or rather, "so you are also of the consolation"; for the apostle seems to respect not future happiness and glory, in which, as there will be no afflictions and troubles, so no comfort under them, but present consolation, which the saints enjoy here as a pledge and earnest of that fulness of joy which they shall have with Christ for evermore.

so shall ye be--rather, "So are ye." He means, there is a community of consolation, as of suffering, between me and you.

And our hope concerning you - Grounded on your patience in suffering for Christ's sake, is steadfast.
