'Appetite' in the Bible

Meanwhile, certain riff-raff among the people had an insatiable appetite for food. As a result, they wept and turned back, and the Israelis cried out, "If only somebody would feed us some meat!

But now our appetite is gone; there’s nothing to look at but this manna!”

That's why the place was named Kibroth-hattaavah, because they buried the people there who had an insatiable appetite for meat.
