2 Corinthians 11:6
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
But though I be rude in speech, yet not in knowledge; but we have been throughly made manifest among you in all things.
Although I am not a polished speaker, I am certainly not lacking in knowledge. We have made this clear to you in every way possible.
