And having in a readiness to revenge all disobedience - I am ready, through this mighty armor of God, to punish those opposers of the doctrine of Christ, and the disobedience which has been produced by them.
When your obedience is fulfilled - When you have in the fullest manner, discountenanced those men, and separated yourselves from their communion. The apostle was not in haste to pull up the tares, lest he should pull up the wheat also.
All the terms in these two verses are military. Allusion is made to a strongly fortified city, where the enemy had made his last stand; entrenching himself about the walls; strengthening all his redoubts and ramparts; raising castles, towers, and various engines of defense and offense upon the walls; and neglecting nothing that might tend to render his strong hold impregnable. The army of God comes against the place and attacks it; the strong holds οχυροματα, all the fortified places, are carried. The imaginations, λογισμοι, engines, and whatever the imagination or skill of man could raise, are speedily taken and destroyed. Every high thing, παν ὑψωμα, all the castles and towers are sapped, thrown down and demolished; the walls are battered into breaches; and the besieging army, carrying every thing at the point of the sword, enter the city, storm and take the citadel. Every where defeated, the conquered submit, and are brought into captivity, αιχμαλωτιζοντες, are led away captives; and thus the whole government is destroyed.
It is easy to apply these things, as far as may be consistent with the apostle's design. The general sense I have given in the preceding notes.
And having in a readiness - I am ready to punish all disobedience, notwithstanding all that is said to the contrary; see the notes on 2 Corinthians 10:1-2. Clothed as I am with this power; aiming to subdue all things to Christ, though the weapons of my warfare are not carnal, and though I am modest or timid 2 Corinthians 10:1 when I am with you, I am prepared to take any measures of severity required by my apostolic office, in order that I may inflict deserved punishment on those who have violated the laws of Christ. The design of this is, to meet the objection of his enemies, that he would not dare to execute his threatenings.
When your obedience is fulfilled - Doddridge renders this: “now your obedience is fulfilled, and the sounder part of your church restored to due order and submission.” The idea seems to be, that Paul was ready to inflict discipline when the church had showed a readiness to obey his laws, and to do its own duty - delicately intimating that the reason why it was not done was the lack of entire promptness in the church itself, and that it could not be done on any offender as long as the church itself was not prepared to sustain him. The church was to discountenance the enemies of the Redeemer; to show an entire readiness to sustain the apostle, and to unite with him in the effort to maintain the discipline of Christ‘s house.
