Garden Eden
The Biblical garden Eden spells out the term “hidden luxury”: The garden is gn, which is derived from an “enclosure”, which also means “protecting” & “hiding” (English garden may also be derived from guarding). The name עדן ˁdn ˁeden is a word that means “luxury”. The garden Eden may thus be a spooky pun to explain how the spook rulers needed to hide their loot from their looted subjects. (And “hidden delights” may be a secondary pun about sexuality, as with the Tree of Knowledge.)
