There is an ancient tradition of supplication between someone in need and their host, called Hiketeia. It was a very important ritual, and was one of the first things I learnt about in my Classics course. And a great explanation of it came from the one and only Wonder Woman
You know the other great thing about this story? Wonder Woman beats up Batman. Oh yeah, you heard me, Wonder Woman is the best.
