2 Corinthians 1:1

1 Paul, an apostle of Christ Jesus by the will of God, and Timothy our brother, To the church of God in Corinth, together with all his holy people throughout Achaia:

2 Corinthians 9:2

2 For I know your eagerness to help, and I have been boasting about it to the Macedonians, telling them that since last year you in Achaia were ready to give; and your enthusiasm has stirred most of them to action.

2 Corinthians 11:10

10 As surely as the truth of Christ is in me, nobody in the regions of Achaia will stop this boasting of mine.
