John Wesley on 2 Corinthians 2:13

I had no rest in my spirit - From an earnest desire to know how my letter had been received. Because I did not find Titus - In his return from you. So I went forth into Macedonia - Where being much nearer, I might more easily be informed concerning you. The apostle resumes the thread of his discourse, 2Cor 7:2, interposing an admirable digression concerning what he had done and suffered elsewhere, the profit of which he by this means derives to the Corinthians also; and as a prelude to his apology against the false apostles.
