Who was also chosen of the churches. — The word, as in Acts 14:23, implies a definite appointment, in this case, obviously, by popular election — on the part of the Macedonian churches. This falls in, it need hardly be said, with the facts of the case as indicated by the use of the first person plural in Acts 20:5, and through the rest of the book.
With this grace. — The word is used, as in 2 Corinthians 8:4; 2 Corinthians 8:6-7, as we familiarly use the word “charity,” for the liberality which was the result of the grace.
To the glory of the same Lord. — Better, if we keep the Received text, of the Lord Himself; but the better MSS. give, of the Lord, only. There is no need of inserting the word “declaration of”; in relation to the glory of the Lord and to your readiness gives a perfectly intelligible sense.
