2 Corinthians 13:10 - Matthew Poole's English Annotations on the Holy Bible

The apostle here lets them know with how much tenderness he dealt with them; and whereas they might have charged him with sharpness in his letters, he assures them, that he therefore had so wrote, that he might prevent sharper dealings with them when he should come to them, by their hearkening to the admonitions of his letter; for otherwise, he tells them, that after he came he must deal more sharply with them in the execution of that power with which Christ had intrusted him. Yet he further tells them, that that power was for their good, not for their harm; for their edification, not for their destruction: which is the same with what he had said, 2 Corinthians 10:8, and in the verse immediately preceding.
