2 Corinthians 7:14

For if in anything I have gloried to him on your behalf, I was not put to shame; but as we spake all things to you in truth, so our glorying also which I made before Titus was found to be truth. [Paul had evidently told Titus that he would find the Corinthians true and loyal, and ready to obey the apostle's letter. Had events proved otherwise, Paul would have been put to shame in the eyes of Titus. But as the apostle, despite the accusations of the Corinthians to the contrary (2 Corinthians 1:15-17), had always spoken truth to them, so he had always been truthful in speaking to Titus about them. Paul's affection for the Corinthians had not caused him to overstep the limits of perfect accuracy while boasting of them to Titus.]
