ISB ~ 2 Corinthians 2 v3

I wrote:Several times Paul refers to a previous letter of “anguish” and “tears” that he sent to reprimand the Corinthians (2 Cor 2:4, 9; 7:8, 12). This may have been 1 Corinthians but is more likely a personal letter that has not survived. Some think the substance of this correspondence is preserved in chaps. 10-13, although arguments for this view remain conjectural.
