Why did Paul refuse support from the Corinthians according to 2 Corinthians 11:12?
Paul refused support from the Corinthians to cut off occasion from those who desired occasion, so that in what they boasted, they might be found even as he was. He kept himself from being burdensome and took support from the poor Macedonian brethren instead.
Les explains that the Corinthian church had well-to-do people who could have supported Paul, yet he spared them. Paul reminded them that he was chargeable to no man; what he lacked, the brethren from Macedonia supplied. Paul kept himself from being burdensome and would continue doing so. Verse 11 gives his motive of love for them, and verse 12 gives the further reason: he would cut off occasion from those who desired occasion, so that wherein they glory, they may be found even as we. Les also notes Macedonia was Northern Greece and Achaia was the southern half of Greece.
But what I do, that I will do, that I may cut off occasion from them which desire occasion; that wherein they glory, they may be found even as we.
