That ye would confirm your love toward him - You do love him, notwithstanding the reproach he has brought on the Gospel; and notwithstanding your love to him, ye were obliged to cut him off for the credit of the Gospel. Now that he has repented, I beseech you to confirm, κυρωσαι, to ratify, by a public act of the Church, your love to him; give him the fullest proof that you do love him; by forgiving him and restoring him to his place in the Church.
Wherefore I beseech you that ye would confirm your love toward him - The word rendered here as “confirm” ( κυρῶσαι kurōsai) occurs in the New Testament only here and in Galatians 3:15. It means to give authority, to establish as valid, to confirm; and here means that they should give strong expressions and assurances of their love to him; that they should pursue such a course as would leave no room for doubt in regard to it. Tyndale has well rendered it: “Wherefore I exhort you that love may halve strength over him.” Paul referred, doubtless, here to some public act of the church by which the sentence of excommunication might be removed, and by which the offender might have a public assurance of their favor.
