Anubis is the god of death (so I don't think quite think Jacob would be living inside of it) Sobek-Ra is the god of life and according to the Wiki doesn't take part in making good, but instead pushes people towards doing good or righting a wrong (lunchbox for Kate?)
The Sayid thing throws a wrench into all of it, did he save his life or make him suffer? (they both probably could have gone past the car if he didn't stop them) Fantastic fucking episode.
..and not that it means anything but the ending where the "LOST" logo came out from the white light was pretty awesome.
Edit: According to the biblical references, Jacob had 12 sons, the last one was named Benjamin.

How the fuck did they manage to work all that in?
