In addition, I looked up the word for 'spirit' as in evil spirit, the kind that would be cast out, like a demon.

That is this:

4 You will be brought down, and will speak out of the ground. Your speech will mumble out of the dust. Your voice will be as of one who has a familiar spirit, out of the ground, and your speech will whisper out of the dust.

*******************

'familiar spirit' is this:


178. 'owb (obe)

from the same as 'ab (apparently through the idea of prattling a father's name); properly, a mumble, i.e. a water skin (from its hollow sound); hence a necromancer (ventriloquist, as from a jar) bottle, familiar spirit.

see HEBREW 'ab
