'Caused' in the Bible

But if anyone has caused grief, he didn't cause me any grief. To some extent I don't want to emphasize this too much it has affected all of you.

If I made you sad with my letter, I do not regret it, although I did regret it then. I see that the letter caused you sorrow, though only for a while.

Who is weak without me being weak, too? Who is caused to stumble without me becoming indignant?
