Matthew Poole and continuators on 2 Corinthians 10:6

6 And having in readiness to revenge all disobedience, when your obedience is fulfilled .

The Apostle certainly means by this, Excommunication; which was the Rod which he had before mentioned: asking them, if they would he should come unto them with a Rod; This Rod he here threatneth them with; telling them, that he had another Weapon of his warfare of a spiritual nature too, to be used against such as preferred themselves to be Believers, but walked disorderly; Only he at present spared them, because though a great part of them were obedient, yet there were some amongst them of whose Obedience he could not yet glory; but yet he hoped well, and therefore should wait, until by the use of all fair means (such as Exhortations, and Arguments) he had reduced as many of them, as he could unto Obedience. But that being done, God had intrusted him with another Weapon, with which he would, in the name and by the authority of God, revenge his glory upon the disobedience of others. Herein the Apostle hath set a Rule and a Pattern to all Churches, where are multitudes that walk disorderly; not to be too hasty in Excommunicating them, but to proceed gradually; first using all fair means, and waiting with all patience for the reducing them to their duty, who will by any gentle, and fair means be reduced; and then revenging the honour and glory of God only upon such as will not be reclaimed.
