Question/Favor… please read!

Okay, so I am writing a thesis, and the topic is hospitality.  More on that to come, I am sure, in the next few months, but for now, I am asking my friends and acquaintances the following question:

When you think of the word hospitality and the bible, what scripture comes to mind?  

And the follow up question is the following:

In terms of practicing hospitality, or practicing radical hospitality, what is the Scriptural support that you find for such practices?  Where does Scripture address the call to practice radical community?


If you have time and interest, please let me know what you think.  I appreciate it in advance.
