Verse 11. How great diligence it wrought in you - Shown in all the following particulars. Yea, clearing of yourselves - Some had been more, some less, faulty; whence arose these various affections. Hence their apologizing and indignation, with respect to themselves; their fear and desire, with respect to the apostle; their zeal and revenge, with respect to the offender, yea, and themselves also. Clearing of yourselves - From either sharing in, or approving of, his sin. Indignation - That ye had not immediately corrected the offender. Fear - Of God's displeasure, or lest I should come with a rod. Vehement desire - To see me again. Zeal - For the glory of God, and the soul of that sinner. Yea, revenge - Ye took a kind of holy revenge upon yourselves, being scarce able to forgive yourselves. In all things ye - As a church. Have approved yourselves to be pure - That is, free from blame, since ye received my letter.
Verse 12. It was not only, or chiefly, for the sake of the incestuous person, or of his father; but to show my care over you.
