In these verses observe,

I.The apostle refuses to justify himself, or to act by such rules as the false apostles did, Co2 10:12. He plainly intimates that they took a wrong method to commend themselves, in measuring themselves by themselves, and comparing themselves among themselves, which was not wise. They were pleased, and did pride themselves, in their own attainments, and never considered those who far exceeded them in gifts and graces, in power and authority; and this made them haughty and insolent. Note, If we would compare ourselves with others who excel us, this would be a good method to keep us humble; we should be pleased and thankful for what we have of gifts or graces, but never pride ourselves therein, as if there were none to be compared with us or that did excel us. The apostle would not be of the number of such vain men: let us resolve that we will not make ourselves of that number.

II.He fixes a better rule for his conduct, namely, not to boast of things without his measure, which was the measure God had distributed to him, Co2 10:13. His meaning is, either that he would not boast of more gifts or graces, or power and authority, than God had really bestowed on him; or, rather, that he would not act beyond his commission as to persons or things, nor go beyond the line prescribed to him, which he plainly intimates the false apostles did, while they boasted of other men's labors. The apostle's resolution was to keep within his own province, and that compass of ground which God had marked out for him. His commission as an apostle was to preach the gospel every where, especially among the Gentiles, and he was not confined to one place; yet he observed the directions of Providence, and the Holy Spirit, as to the particular places whither he went or where he did abide.

III.He acted according to this rule: We stretch not ourselves beyond our measure, Co2 10:14. And, particularly, he acted according to this rule in preaching at Corinth, and in the exercise of his apostolical authority there; for he came thither by divine direction, and there he converted many to Christianity; and, therefore, in boasting of them as his charge, he acted not contrary to his rule, he boasted not of other men's labours, Co2 10:15.

IV.He declares his success in observing this rule. His hope was that their faith was increased, and that others beyond them, even in the remoter parts of Achaia, would embrace the gospel also; and in all this he exceeded not his commission, nor acted in another man's line.

V.He seems to check himself in this matter, as if he had spoken too much in his own praise. The unjust accusations and reflections of his enemies had made it needful he should justify himself; and the wrong methods they took gave him good occasion to mention the better rule he had observed: yet he is afraid of boasting, or taking any praise to himself, and therefore he mentions two things which ought to be regarded: - 1. He that glorieth should glory in the Lord, Co2 10:17. If we are able to fix good rules for our conduct, or act by them, or have any good success in so doing, the praise and glory of all are owing unto God. Ministers in particular must be careful not to glory in their performances, but must give God the glory of their work, and the success thereof. 2. Not he that commendeth himself is approved, but he whom the Lord commendeth, Co2 10:18. Of all flattery, self-flattery is the worst, and self-applause is seldom any better than self-flattery and self-deceit. At the best, self-commendation is no praise, and it is oftentimes as foolish and vain as it is proud; therefore, instead of praising or commending ourselves, we should strive to approve ourselves to God, and his approbation will be our best commendation.

We dare not make ourselves, etc. - As if he had said: I dare neither associate with, nor compare myself to, those who are full of self-commendation. Some think this to be an ironical speech.

But they, measuring themselves by themselves - They are not sent of God; they are not inspired by his Spirit; therefore they have no rule to think or act by. They are also full of pride and self-conceit; they look within themselves for accomplishments which their self-love will soon find out; for to it real and fictitious are the same. As they dare not compare themselves with the true apostles of Christ, they compare themselves with each other; and, as they have no perfect standard, they can have no excellence; nor can they ever attain true wisdom, which is not to be had from looking at what we are but to what we should be; and if without a directory, what we should be will never appear, and consequently our ignorance must continue. This was the case with these self-conceited false apostles; but ου συνιουσιν, are not wise, Mr. Wakefield contends, is an elegant Graecism signifying they are not aware that they are measuring themselves by themselves, etc.

For we stretch not ourselves beyond our measure,.... They did not go beyond the bounds set them by the purpose and providence of God, by going to Corinth; nor did they boast of things without their measure, when they spoke of their labours, and of the success of their ministrations among them; nor did they assume and arrogate to themselves what did not belong to them, when they claimed an authority over them, and a right of exercising their apostolical office among them:

as though we reached not unto you; by right, or according to the will of God, and the measuring line and bounds he drew and fixed for them:

for we are come as far as to you also in preaching the Gospel of Christ. The case is clear, it is a plain matter of fact, that they were not only come to other places, where they had preached the Gospel, and planted churches, but as far as to Corinth also, where they came "in, by, or with the Gospel of Christ": not their own, or what was of their own invention, but Christ's; of which he is the author, minister, and subject; they did not come without something with them; they came with the good news and glad tidings of salvation by Christ; they came preaching the Gospel, which was owned for the conversion of many souls, and for the raising a very considerable church; all which was a full proof that they were of right, and not by usurpation, come to them; that they had not thrusted themselves in, where they had no business, and consequently still retained a power over them.

"We do not presume (irony) to judge ourselves among, or in comparison with, some of them that commend themselves." The charge falsely brought against him of commending himself (Co2 3:1; Co2 5:12), really holds good of the false teachers. The phrase, "judge ourselves of the number," is drawn from the testing of athletes and senators, the "approved" being set down on the roll [WAHL].

measuring themselves by themselves--"among themselves": to correspond to the previous verb, "judge ourselves among them." Instead of measuring themselves by the public standard, they measure themselves by one made by themselves: they do not compare themselves with others who excel them, but with those like themselves: hence their high self-esteem. The one-eyed is easily king among the blind.

are not wise--with all their boasted "wisdom" (Co1 1:19-26), they are anything but "wise."
