require (something) of (someone or something)
To have a necessity or requisite provided by someone or something. Typically used when the required thing is vague or unspecified ("from" is more often used after "require" when the thing is specified). There are a few things we require of you before we can begin processing your information. We're still a little unclear as to what is required of us in this arrangement.
