'Below' in the Bible

Sheol below is stirred up about you, ready to meet you when you arrive. It rouses the spirits of the dead for you, all the former leaders of the earth; it makes all the former kings of the nations rise from their thrones.

Look up at the sky! Look at the earth below! For the sky will dissipate like smoke, and the earth will wear out like clothes; its residents will die like gnats. But the deliverance I give is permanent; the vindication I provide will not disappear.
