2 Corinthians 8:18-21

Verse 18

The brother, whose praise is in the Gospel - Who this brother was we cannot tell; some suppose it was St. Luke, who wrote a gospel, and who was the companion of St. Paul in several of his travels; others think it was Silas; others, Barnabas; others, Mark; and others, Apollos. Neither ancients nor moderns agree in either; but Luke, John, and Mark, seem to have the most probable opinions in their favor. Whoever the person was he was sufficiently known to the Corinthians, as we learn by what the apostle says of him in this place.
Verse 19

Chosen of the Churches to travel with us - Χειροτονηθεις· Appointed by a show of hands; from χειρ the hand, and τεινω, to extend. This appointment, by the suffrage of the Churches, seems to refer more to St. Luke than any one else; unless we suppose he refers to the transaction, Act 15:40, Act 15:41, and then it would appear that Silas is the person intended.

With this grace - Liberal contribution. See on 2Cor 8:1 (note).

Your ready mind - Your willingness to relieve them. But, instead of ὑμων, your, ἡμων, our, is the reading of almost all the best MSS. and all the versions. This is, doubtless, the reading.
Verse 20

Avoiding this, that no man should blame us - Taking this prudent caution to have witnesses of our conduct, and such as were chosen by the Churches themselves, that we might not be suspected of having either embezzled or misapplied their bounty, See the note on 1Cor 16:4.
Verse 21

Providing for honest things - Taking care to act so as not only to be clear in the sight of God, but also to be clear in the sight of all men; avoiding even the appearance of evil. I wish the reader to refer to the excellent note on 1Cor 16:4 (note), which I have extracted from Dr. Paley.
