'Ashamed' in the Bible

But God chose what is nonsense in the world to make the wise feel ashamed. God chose what is weak in the world to make the strong feel ashamed.

I'm not writing this to make you feel ashamed, but to warn you as my dear children.

I say this to make you feel ashamed. Has it come to this, that there is not one person among you who is wise enough to settle disagreements between brothers?
