Avraham our forefather taught us the special quality of hospitality. Through food, drink and bed he welcomed in visitors into his home. There was one more detail to Avraham's hospitality that was so critical: he would escort his guests. Why was this so necessary? Ultimately he had given them what they needed, so why did he need to see them out too? There is a specific virtue behind the gesture of escorting one's guests that is the key to authentic hospitality.
