Is it possible to use the relative pronoun "which" to refer to people?

All of the grammar books I have consulted indicate that who(m)/that are the only relative pronouns to be used with people.

I thought that you could use "which" when you point out a specific person in a group. Is this not acceptable/ is there a situation where one could use "which" to refer to a person directly?

A quick google search for "the man which" revealed several bible passages with this combination, but nothing in the line of grammar explanations.

Purdue's Online Writing Lab provides this chart when talking about relative pronouns:

Note that people are referred to only by the relative pronouns who and that (the latter in informal English only), while things and concepts are referred to by which.

Another website for English language help, TutorPal.com, explains that the use of "which" to refer to people is one of the ways that the King James Bible's English differs from modern English:

Use of relative pronouns: In Middle English, the language of King James, we find “which” in many instances where we could expect “who.” For example, “Our father which art in heaven.”

So to answer your question, using which to refer to people used to be acceptable, but now it's not.
