Adam Clarke on 2 Corinthians 7:2

Receive us - Χωρησατε ἡμας. This address is variously understood. Receive us into your affections - love us as we love you. Receive us as your apostles and teachers; we have given you full proof that God hath both sent and owned us. Receive, comprehend, what we now say to you, and carefully mark it.

We have wronged no man - We have never acted contrary to the strictest justice.

We have corrupted no man - With any false doctrine or pernicious opinion.

We have defrauded no man - Of any part of his property. But what have your false teachers done? They have beguiled you from the simplicity of the truth, and thus corrupted your minds. 2Cor 11:3. They have brought you into bondage; they have taken of you; devoured you; exalted themselves against you, and ye have patiently suffered all this. 2Cor 11:20. It is plain that he refers here to the false apostle or teacher which they had among them.
