2 Corinthians 7:12

But that your earnest care for us might be made manifest (all eineken tou panerwqhnai thn spoudhn umwn thn uper hmwn). So the correct text, not "our care for you." Easy to interchange Greek umwn (your) and hmwn (our). Usual construction with preposition eneken and genitive of articular infinitive with accusative of general reference.
