'Ashamed' in the Bible

For if I have been doing some boasting about you to him, I have never been ashamed of it. Moreover, since everything we told you was true, our boasting to Titus has also proved to be true.

So if I boast a little too much about our authority, which the Lord gave us to build you up and not to tear you down, I will not be ashamed of it.

I am ashamed to admit it, but we have been too weak for that. Whatever anyone else dares to claim I am talking like a fool I can claim it, too.
