2 Corinthians 12:16-19 NIV

[16] Be that as it may, I have not been a burden to you. Yet, crafty fellow that I am, I caught you by trickery! [17] Did I exploit you through any of the men I sent to you? [18] I urged Titus to go to you and I sent our brother with him. Titus did not exploit you, did he? Did we not walk in the same footsteps by the same Spirit? [19] Have you been thinking all along that we have been defending ourselves to you? We have been speaking in the sight of God as those in Christ; and everything we do, dear friends, is for your strengthening.
