Moreover, brethren, we do you to wit of the grace of God bestowed on the churches of Macedonia;
We do you to wit - Greek, 'BUT we make known to you:' while "I have confidence in you" (2 Corinthians 7:16) I acquaint you with the Macedonians' liberality, which ye ought to imitate.
The grace of God bestowed on (literally, in: in the case of) the churches of Macedonia. Their liberality was not of themselves, but of God's grace bestowed on them, whereby they became instruments of "grace" to others (2 Corinthians 8:6; 2 Corinthians 8:19). The importance given to the collection arose from Paul's engagement (Galatians 2:10), and chiefly from his hope to conciliate the Judaizing Christians at Jerusalem to himself and to Gentile believers by an act of love on the part of the latter toward their Jewish brethren.
