[Splendour]

I also found this bit of scripture that speaks more specifically about voodoo type practices:

Isaiah 8:11

A Boulder Blocking Your Way
11-15God spoke strongly to me, grabbed me with both hands and warned me not to go along with this people. He said:
"Don't be like this people,
always afraid somebody is plotting against them.
Don't fear what they fear.
Don't take on their worries.
If you're going to worry,
worry about The Holy. Fear God-of-the-Angel-Armies.
The Holy can be either a Hiding Place
or a Boulder blocking your way,
The Rock standing in the willful way
of both houses of Israel,
A barbed-wire Fence preventing trespass
to the citizens of Jerusalem.
Many of them are going to run into that Rock
and get their bones broken,
Get tangled up in that barbed wire
and not get free of it."

16-18Gather up the testimony,
preserve the teaching for my followers,
While I wait for God as long as he remains in hiding,
while I wait and hope for him.
I stand my ground and hope,
I and the children God gave me as signs to Israel,
Warning signs and hope signs from God-of-the-Angel-Armies,
who makes his home in Mount Zion.

19-22When people tell you, "Try out the fortunetellers.
Consult the spiritualists.
Why not tap into the spirit-world,
get in touch with the dead?"
Tell them, "No, we're going to study the Scriptures."
People who try the other ways get nowhere—a dead end!
Frustrated and famished,
they try one thing after another.
When nothing works out they get angry,
cursing first this god and then that one,
Looking this way and that,
up, down, and sideways—and seeing nothing,
A blank wall, an empty hole.
They end up in the dark with nothing.

Note that this sounds curiously like what we are suppose to be doing today.
