Stranger

Hello all, I'm just going to hop in with my own question...

I've been trying to remember the origins of the phrase, 'Stranger in a Strange Land'.
It is the title of a popular sci-fi novel by R. Heinlein, but has also been used to describe people in many other instances (Dracula, for instance).
I seem to remember it being used in reference to Abraham, in Genesis, but I haven't been able to find it again.

Let me know if you have any suggestions (or if it's been used anywhere else)
