(22) And we have sent with them our brother.--Who this second unnamed brother was is again simply matter of conjecture. Of the names connected with St. Paul at this period, that of Tychicus seems to have the greatest balance of probabilities in its favour. He went up with St. Paul to Jerusalem on this very business (Acts 20:4), and the tone in which the Apostle speaks of him in Ephesians 6:21, Colossians 4:7, exactly agrees with his language here. In 2Timothy 4:12, Titus 3:12, we have further evidence of his being one of the most trusted of the couriers, or "messengers," of the Apostolic Church. The name of Clement has, however, I think, some claim to consideration. St. Paul refers to him as an active fellow-worker (Philippians 4:3). He was connected with the Philippians. Assuming his identity with Clement of Rome, this gives him a point of contact with the Church of Corinth, to which Clement addressed his Epistle. On the other hand, the distinction drawn in 2Corinthians 9:4 between these brethren and the Macedonians may seem to exclude Clement, as it has been thought to exclude Aristarchus and Sopater and Secundus. The word translated "diligent" ("earnest" in 2Corinthians 8:16) is used by St. Paul only in this passage. It implies what we might almost call the "business-like" side of the Christian type of character, and is therefore employed with special fitness here.

Verse 22. - Our brother. It is impossible to conjecture with any certainty who was the brother thus warmly eulogized. Clement, Epaenetus, Apollos, Luke, Zenas, Sosthenes, Trophimus, and Tychicus have all been suggested. Stanley conjectures that the two who accompanied Titus were the Ephesians Tychicus and Trophimus (Acts 20:4; Acts 21:9; 2 Timothy 4:12; Ephesians 6:21; Titus 3:12; Colossians 4:7).

8:16-24 The apostle commends the brethren sent to collect their charity, that it might be known who they were, and how safely they might be trusted. It is the duty of all Christians to act prudently; to hinder, as far as we can, all unjust suspicions. It is needful, in the first place, to act uprightly in the sight of God, but things honest in the sight of men should also be attended to. A clear character, as well as a pure conscience, is requisite for usefulness. They brought glory to Christ as instruments, and had obtained honour from Christ to be counted faithful, and employed in his service. The good opinion others have of us, should be an argument with us to do well.And we have sent with him our brother,.... This is a third person sent about this business. The apostle, in this, conformed to the customs of his nation; at least if he did not purposely do it, it agrees with the Jewish canons, which require three persons for the distribution of alms.

"The alms dish, (they say (x)) is by three; nor do they appoint "overseers" of it "less than three".''

Again, they say (y),

"the poor's chest is collected by two, "but distributed by three"; it is collected by two, because they do not appoint governors over a congregation less than two, and it is distributed by three, even as pecuniary judgments; but the alms dish is collected by three, and distributed by three; for the collection and distribution are alike:''

who this brother was, sent by the apostle with Titus and the other person, is as uncertain as the former. Some think it was Luke, others Apollos, others Timothy, others Sosthenes, others Epaenetus, others Silas, others Zenas the lawyer; a brother he was, and a very considerable character is given of him:

whom we have oftentimes proved diligent in many things; he was a very diligent and industrious man, and so fit for this service; he had been tried and proved, and was found to be so, not only once or twice, but oftentimes; and that not in a few instances, but in many; and in nothing did he ever show more diligence than in this matter:

but now much more diligent; than ever he had been in anything before:

upon the great confidence which I have in you; what doubled and increased this brother's diligence, and made him so eager for, and forward to this work, was, his observing the great confidence the apostle expressed of the very great readiness and liberality of the Corinthians; and which tacitly carries in it an argument exciting them thereunto: or this last clause may be read, "which he hath in you"; and so regards the confidence this brother had in them, which made him so ready to engage with, and join the other messengers.
