'Appetite' in the Bible

Therefore Sheol's appetite has grown; it has opened its mouth beyond limit. Jerusalem's nobility and her multitudes will go there, along with her brawlers and whoever is reveling within her.

Meanwhile, the dogs have a mighty appetite they can never get enough. And as for them, they are the shepherds who lack understanding; they have all turned to their own way, each one to his gain, each and every one.
