GEN900 Jewish tradition derives several still-binding principles of hospitality and good manners from Abraham’s behavior:   Receive your guests warmly and enthusiastically.   … By displaying such enthusiasm, Abraham made his guests feel welcome.  Think first of what your guests most need. [water, food, rest, etc.]   …  Deliver more than you promise. … The Talmud Baba Metzia 87a infers from Abraham’s behavior that one of the “distinguishing characteristics of righteous people” is that “they say little but do a lot.”   [See, also, Avot 1:15 – AJL] In addition, by telling guests that you are preparing only a little, they’ll feel less self-conscious about accepting the invitation.  Personally attend to your guest’s needs.  Abraham had a large staff Genesis 14:14, but he waited on his guests himself Genesis 18:8. We learn from this that even if you have maids and other employees, make sure to do some of the work for your guests with your own hands.   TELVOL 2:44-45
