'Malachi' - meaning? PLEASE read this. (solved)

I´ve read this FAQ and the one from "Children of the corn" and I know that it´s a character in that movie and the novel.

BUT that´s not what I´m asking.

I recall I dialogue from this Western "Silverado", where Danny Glover´s character Mal Johnson comes home and his father tells him, he was chasen off his own land, he´d had his farm occupied by the bad guys and then he says:

"Malachai ... I live in the wilderness like a wildcat..."

(sorry I retranslated this by memory from the german DVD, but that old man definitely says "Malachi/Malachai").

So, since it was without any connection to "Children..." in THIS movie, there actually must be another, earlier meaning than that out of "Children...".
There must be another meaning, which I wasn´t able to find out by research, english wiki etc. When I go to wiki or just google, there´s just the hint to "Children...".

Is that an older term for a dismissed animal (e.g. a "wildcat") or a mythological creature like a "Wendigo" or another term for "maverick", "Desparado" "Loner" or what????

Please can someone explain me the meaning of this term?

Thank you.
