(10) As the truth of Christ is in me . .--The formula is almost, though not quite, of the nature of an oath. He speaks here, as in Romans 9:1, in the consciousness that the truth of Christ (the objective sense of the truth revealed in Christ seems almost merged in the subjective sense of the truthfulness that was of the essence of His nature) dwells in him, and that therefore he cannot but speak "the truth, the whole truth, and nothing but the truth."

No man shall stop me of this boasting.--Literally, This boast shall not be stopped for me. The verb for "stop" means primarily to "hedge round," or "fence." In the New Testament, as in Romans 3:19, it is always used of "stopping the mouth." Here, with something like a personification, he says that his boast shall not have its mouth thus sealed.

In the region of Achaia.--The word (klima) is peculiar to St. Paul among the writers of the New Testament (Romans 15:23; Galatians 1:21). Like our word "climate," which is derived from it, it was originally a term of science, and had passed gradually into colloquial usage. He names the province and not the city--probably to include Cenchreae. There is no evidence of his having preached in any other locality south of the Isthmus of Corinth.

Verse 10. - As the truth of Christ is in me. The strength of St. Paul's feelings on the subject has already been expressed in 1 Corinthians 9:15. We have a similar appeal in Romans 9:1. The "as" is not in the original, but evidently the words are meant for a solemn asseveration - "The truth of Christ is in me, that," etc. No man shall stop me of this boasting; literally, this shall not be stopped as concerns me. The verb means literally, "shall be fenced," and with that tendency to over elaboration which is frequent in commentators, some suppose that St. Paul referred to the projected wall across the isthmus of Corinth, etc. But the same word is used for simply stopping the mouth in Romans 3:19; Hebrews 11:33. In the regions of Achaia. He would not apply the rule to Corinth only, but seems to have felt the need for the utmost circumspection, and for cutting off every handle for suspicion or slander among these subtle, loquacious, intellectual Greeks. He could act more freely among the more frank and generous Macedonians.

11:5-15 It is far better to be plain in speech, yet walking openly and consistently with the gospel, than to be admired by thousands, and be lifted up in pride, so as to disgrace the gospel by evil tempers and unholy lives. The apostle would not give room for any to accuse him of worldly designs in preaching the gospel, that others who opposed him at Corinth, might not in this respect gain advantage against him. Hypocrisy may be looked for, especially when we consider the great power which Satan, who rules in the hearts of the children of disobedience, has upon the minds of many. And as there are temptations to evil conduct, so there is equal danger on the other side. It serves Satan's purposes as well, to set up good works against the atonement of Christ, and salvation by faith and grace. But the end will discover those who are deceitful workers; their work will end in ruin. Satan will allow his ministers to preach either the law or the gospel separately; but the law as established by faith in Christ's righteousness and atonement, and the partaking of his Spirit, is the test of every false system.As the truth of Christ is in me,.... To show the firmness of his resolution, and how determined he was to abide by it, he joins an oath to it; for these words are the form of an oath; and it is as if he should say, as sure as Christ is truth, who is in me; or as that the truth of grace, or the truth of the Gospel of Christ is in my heart and mouth, so sure will I constantly persevere in this determination; or let the truth of Christ never be thought to be in me, if I do not:

no man shall stop me of this boasting in the regions of Achaia; or this boasting shall not be stopped in me; of preaching the Gospel freely at Corinth, and that he had not been chargeable and burdensome to them; nor would he be for time to come, neither there, nor in any part of Achaia, of which Corinth was the metropolis; See Gill on 2 Corinthians 9:2. No man should stop his mouth from boasting of this, by putting anything into his hands, for he was determined not to receive anything from any person in these climates; not but that he reserved a liberty in himself to receive from other persons and churches, for his comfortable subsistence, and so much the limitation of his resolution to these parts implies; for if he had not intended to have received a supply from any persons whatever, the restriction to the regions of Achaia would have been unnecessary; and he should rather have said, that no man should stop him of this boasting in any part of the world. The Vulgate Latin version reads, "this boasting shall not be broken"; and to the same sense the Syriac version, "this boasting shall not be abolished".
