Help!

I am doing a project for school and I am in need of some help.

I am looking for a verse and I can’t remember where I’ve read it and I need it for the project. The verse has something to do with this: When you sin against a person, you are not only sinning against them, you are sinning against God (because man was made in Gods image). If you think you might know, please please let me know before Tuesday!!

Ps: It is not Psalm 51 or in James (unless I missed it).
