'Underworld' in the Bible

They will say to you, "Seek oracles at the pits used to conjure up underworld spirits, from the magicians who chirp and mutter incantations. Should people not seek oracles from their gods, by asking the dead about the destiny of the living?"

The Egyptians will panic, and I will confuse their strategy. They will seek guidance from the idols and from the spirits of the dead, from the pits used to conjure up underworld spirits, and from the magicians.

You will fall; while lying on the ground you will speak; from the dust where you lie, your words will be heard. Your voice will sound like a spirit speaking from the underworld; from the dust you will chirp as if muttering an incantation.
