2 Corinthians 11:6

But though I be rude in speech, yet not in knowledge; but we have been throughly made manifest among you in all things.

But though I am unskilled in speech, yet I am not unskilled in knowledge. No, in every way we have been revealed to you in all things.

But though `I be' rude in speech, yet `am I' not in knowledge; nay, in every way have we made `this' manifest unto you in all things.

and even if unlearned in word -- yet not in knowledge, but in every thing we were made manifest in all things to you.

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.
