"Support of" vs. "Support for"

"Show your support for the XYZ (Organization name) this season" or "Show your support of XYZ (Organization name) this year"?

I have seen support of and support for both being used. Is there a rule?

"Show your support of our clients" or "show your support for our clients"? (Support to be used in the context of making a donation)


Support of an organization means that it is the organization that is giving the support. Support for an organization means that the organization is receiving support.
