One thing that struck me as I was reading “A Very Old Man With Enormous Wings” was the complete lack of hospitality towards the angel. Hospitality was an important value for many ancient civilizations. In a time when people lived further apart, being turned away into the wilderness could be a death sentence. As a result guests were not supposed to be turned away and there was an expectation that the guest would be treated well. The bible actually explicitly states “Do not neglect to show hospitality to strangers, for by this some have entertained angels without knowing it” Hebrew 13:2.
This attitude was not unique to the Ancient Israelite’s. The Greeks also had similar expectations and potential rewards. The Ancient Greeks called hospitality Xenia. Xenia was a reciprocal relationship of mutual respect (perhaps even mutual recognition) between the host and guest. In many Greek myths Zeus, god of lightning and protector of travelers, would take the form of a traveler and depending on how he was treated would either punish or reward who did (or worse yet, didn’t) host him. The message was clear, you never knew which guest was Zeus so you better treat them right.
